Category: Decentralised Finance (DeFi)

Decentralized Finance (DeFi) is a sector within the cryptocurrency and blockchain space which aims to provide a decentralized version of the products available in traditional finance- without central control and at a lower cost with potentially higher returns. These products include loans, interest-bearing deposits and borrowing services.

The advantages of decentralized finance are that it addresses the problems we have with the traditional banking system. For example, decentralized finance protocols are controlled by multiple people, and all participants are required to abide by the rules written into the smart contracts underlying the protocols.

  • Vortex DeFi ($VTX): One-stop Gateway to DeFi

    Vortex DeFi ($VTX): One-stop Gateway to DeFi

    Vortex DeFi ($VTX) aims to provide users a one-stop access to all leading decentralized finance (DeFi) platforms and protocols from a single web-based user interface.

    Decentralized Finance (DeFi) has evolved from a niche subcategory to the biggest catalyst driving the cryptocurrency and blockchain field today. It’s primarily focused on the Ethereum network, which has the majority of the DeFi share. There are, however, a large number of core DeFi protocols, combinators, and countless forks. All of this can become confusing fast.

    Fortunately, users don’t have to delve into the complex workings and nuances of these protocols, which can be overwhelming even for long-term users. Vortex DeFi is introduced to simplify the access and exposure to the sector. It has integrations with different protocols, which abstracts away the complexity in a simple and yet intuitive interface, to level the playing field and ensure greater participation.

    Background

    Vortex DeFi launched in Aug 2020 through a private investment round. It accrued interest and funding from X21 Digital, DuckDao, Moonrock Capital, Magnus Capital, Pluto Digital Assets PLC, Faculty Capital, A195 Capital, etc. A public sale will be held soon.

    It has a multicultural team, led by CEO Rahul Singh and strategic advisor Lester Lim. The other prominent team members are technical lead Arun Sunil and product lead Shaz. All team members have previous experiences in market-leading companies and blockchain projects.

    What is Vortex DeFi?

    Vortex DeFi is a web-based DeFi management system or a comprehensive DeFi aggregative solution platform, serving as a bridge between Ethereum and Polkadot. It combines the functionality and power of core protocols in a sleek dashboard to allow users of all categories to engage in yield farming. The core services provided are NFT asset management, lending and borrowing, insurance, and exchange.

    Vortex DeFi will also utilize the yEarn finance protocol to access and extract value from various lending protocols to enable automated profitable yield farming. The added advantage of cross-chain compatibility ensures that users don’t have to choose between two promising blockchains. Vortex DEFI also has several components, taking the guesswork and experimentation out of the process.

    Vortex DEFI – Components

    V-Swap

    Being the Uniswap or Bancor equivalent of Vortex, V-Swap will offer an automated digital assets exchange on the Ethereum and Polkadot blockchain. It’s likely to offer liquidity aggregation from multiple sources, so a peer to peer exchange of tokens can be performed without a direct counterparty or orderbook.

    V-Pay

    It will offer a fiat gateway for users, so they can acquire and sell crypto assets from FIAT, in their cards or bank accounts. This is required for onboarding new users, as well as ensuring that they have a way for realizing their returns.

    V-Yield

    A yield aggregator as the name goes, V-Yield will combine yield from different sources and optimize them according to the best return rate. It will spare users from the trouble of manually finding sources and having the need to rotate them.

    V-NFTs

    An asset management, V-NFTs will allow users to manage their asset collection and swap them for each other. Given that NFTs are an illiquid asset class and their infrastructure is scattered, it’s hugely important to develop a unified interface.

    V-Insure

    DeFi protocols are rife with exploits and smart contract risks. Therefore, to onboard new users and even to retain existing ones, it’s necessary to grant them peace of mind by ensuring the protection of their funds. V-Insure will seek to insure user funds by seeking out integrations with multiple DeFi insurance protocols.

    Vortex DEFI Native Token ($VTX)

    The native token of the platform is Vortex DeFi Token ($VTX), ERC-20 token, which will be used to incentivize users. It has four purposes:

    1. Liquidity pools (LP) rewards are distributed in VTX
    2. Usage for staking on the platform.
    3. Holding VTX tokens allows users to save on the platform fees
    4. The team has announced plans to regularly buy tokens and burn them every quarter to reduce supply and increase the value of existing tokens.

    All of these benefits and value accrual mechanisms will motivate users to hold tokens, in anticipation of rising demand and prices.

    $VTX Token Metrics

    The VTX token has a total supply of 100M $VTX and an initial circulating supply of $0.4M $VTX.

    Funding Rounds

    Private Sale (concluded): 32,500,000 VTX sold at 0.0276 USD per token.(25% TGE, 75% vesting over 120 days)

    Public Sale (on 28 February 2021): 2,500,000 VTX to be sold at 0.04 USD per token. No vesting period.*

    Advantages of Vortex DeFi

    The platform offers users the advantages of a unified DeFi management dashboard, the ability to fuse several protocols together offering a seamless experience with abstracted complexity, powerful lend and earn functionality, automated rotation of funds for optimized returns, non-custodial function, and insurance against loss of funds.

    Vortex DEFI Connected Protocols

    Vortex DeFi connected protocols (source: Introducing Vortex DeFi Beta & Access to the Vortex of DeFi‘ medium article)

    Vortex DEFI will have integrations with several key DEFI protocols, including but not limited to Maker DAO, Compound, Kava, Idle, Aave, Yearn, Uniswap, Nexus Mutual, Curve. This will allow for a powerful user experience, which is likely to improve penetration of decentralized finance.

    Vortex Vision

    The team hopes that Vortex will become the top one-stop solution for a user’s DeFi needs and allow them to simplify their experience. Vortex hopes to make financial applications accessible and simple for all users, regardless of their technical expertise. It will also allow saving on transaction fees (gas) by batching and combining transactions.

    Vortex can also enhance the decentralization level of DeFi protocols by ensuring broad participation and an increase in user activity. Furthermore, it will feature the DAAS (DeFi-As-A-Service) business model. Currently, the product is in development and more changes are expected as the platform launch draws near.

    Conclusion

    DEFI was founded on the principle of openness, equal opportunity, transparency, trustlessness, lack of centralized control, fast processing, and lego-like composability. It is generally presented as a superior alternative to the traditional financial system, which differs heavily from the principles of the crypto community and disallows these services to a large number of people.

    On the other hand, DeFi is accessible to almost everyone with an internet connection and a personal computing device or smartphone. However, primitive user interfaces and experiences of the existing DeFi protocols were a problem. Thankfully, Vortex will overlap the strong functionality of these protocols with an amazing and simple interface.

    Currently, there is a lack of dashboard-style platforms connected to multiple DEFI protocols, aggregating their services and offering a one-stop solution. All of this is about to change with the Vortex launch, which is likely to onboard a large number of new users as well as provide a novel interesting solution to the existing ones.

  • Unido ($UDO): Crypto Banking and DeFi for Enterprise

    Unido ($UDO): Crypto Banking and DeFi for Enterprise

    Unido ($UDO), powered by Polkadot, provides enterprises crypto-asset management solutions, that specialize in governance, security, and interoperability within the crypto banking sphere guaranteeing the satisfaction of all users.


    Background

    Powered by Web3 blockchain Polkadot, Unido was founded by Chris Weddle who has over 20 years of experience within the blockchain sector. The project was initiated in 2017 and is anchored by an experienced team of finance experts, software developers, and blockchain developers. They all come from well-known financial and development firms such as Goldman Sachs, Wipro, and Macquarie.

    Unido’s Founder: Chris Weddle (Source: Unido website)

    Through the Unido project, the team has successfully managed to solve security and accessibility challenges with its distinct and dynamic implementation of a blockchain-based management tool that facilitates the handling of crypto assets.

    What is Unido?

    Unido is a technology ecosystem that addresses the governance, security, and accessibility challenges of decentralized applications, and enables companies to manage crypto assets and capitalize on DeFi.

    Unido’s distinct protocol facilitates investment in DeFi by leveraging its efficient proprietary and multi-sig key signing technology. Furthermore, users have the unique capability to manage crypto banking operations in complete security.

    Under the decentralized platform, assets management enterprises and crypto native companies are ensured agility and efficiency for the custody of their respective digital assets. This creates a strong bridge for firms and organizations to interface with DeFi networks as they remain compliant with licensing and regulatory requirements.

    The platform’s algorithm works best by leveraging, as well as supplying clients with a great deal of crypto trading, payments, and banking solutions.

    Through Unido’s user-friendly protocol, participants essentially have access to three main features all responsible for the system’s special implementation of the blockchain, namely, Enterprise Crypto Banking Suite, DeFi Vault Access, and Governance/Security features.

    Enterprise Crypto Banking Suite

    A business banking portal, through which firms can manage day-to-day operations and capital expenditure. This feature empowers users with a multi-user wallet management protocol that creates, assigns, and manages clients’ wallets.

    Additionally, it is equipped with user governance tools providing access to rights and access requirements unique to the blockchain solution. Overall, this business banking portal is a simple and intuitive instrument with an interoperable, modular architecture that provides analytics on DeFi transactions, activities, and trends.

    DeFi Vault Access

    The vault access is a multi-signature enterprise wallet or DeFi vault used to store, manage, and invest digital assets in an efficient and safe manner.

    The team behind the wallet describes it as a secured and most importantly, a well-integrated bridge into several prominent DeFi investment solutions such as UniSwap, Yearn Finance, and Balancer. Additionally, the vault provides users with a complete overview of investment opportunities within the DeFi space, as well as potential returns and benefits within specific DeFi networks.

    Supported by a portfolio performance dashboard, this feature facilitates the management and investment of digital funds.

    Governance and Security

    Through this blockchain-based feature, the Unido enterprise platform (EP) provides users with an array of security and management instruments ensuring the safety of all funds within the platform.

    The Unido platform guarantees blockchain-based security and agnostic architecture, rendering it versatile and applicable to any given on-chain use cases. Powered by a key signing technology, Unido EP ensures flexible and trustworthy governance, which provides assets access only to permitted entities and parties.

    Unido Token ($UDO)

    The platform’s utility token, $UDO, is the fuel behind Unido’s efficient implementation as it is used to drive network access, ensure transaction security, governance, and network management. Overall, the token is built on a trustworthy smart contract algorithm guaranteeing the development and expansion of the Unido network in the future.

    Furthermore, the token facilitates access to the platform’s variety of products to all users, including institutions and developers. UDO has three main use cases, being network access licenses, consumption fees, and DAO Governance.

    $UDO Tokenomics

    Total Supply: 115,000,000 UDO

    Initial Market Cap: $487,813

    Seed/Private/Pre-Public Sale Fundraising: $1,400,000

    Seed Sale: $0.04, 0% TGE, 20% monthly unlock

    Private Sale: $0.05, 25% TGE, 25% monthly unlock

    Public Sale:: $0.06, full unlock

    Deflationary Economics:

    • Phase 1: From consumption fees, 60% burn, 20% to EDF, and 20% into reserve. Phase 1 when token supply is reduced by 20%.
    • Phase 2: After enterprise products take off, 50% of fees to be invested into EDF & 50% into reserve.

    UDO Use Cases

    Network Access License

    All applications and Unido EP features will only be available via a license purchasable with the UDO token. Once the license is bought, the tokens are removed from circulation and placed into a secured smart contract until the license eventually expires.

    Companies are provided with annual licenses for the Unido platform, where fees are determined by the volume of usage for the target clients and the number of users.

    Consumption Fees

    All fees and consumption charges within the Unido ecosystem and auxiliary platform will be based on the volume of usage within the platforms. Additionally, UDO will be used to authenticate each transaction within its parent platform.

    All operations from developers will either be charged under a subscription model, Freemium model, paid model, or In-App model, all depending on the user specifications and needs.

    DAO Governance

    In general, the DAO will oversee Unido’s Ecosystem Development Fund (EDF) and allow for the subsidizing of new applications implementation and development, which will contribute to the diversification of the platform.

    Unido Ecosystem (source: Unido one-pager)

    Conclusion

    Unido EP aims to be a leader within the blockchain space by spearheading the race toward mass adoption; especially within the traditional financial sector. The platform’s drive to provide secured banking management tools is a great boost for wide DLT acceptance.

    Overall the Polkadot-based platform is a dynamic implementation of decentralized technology, which guarantees total accessibility and security through key features lacking in most solutions of its genre on the market.

    Unido Enterprise Platform is ahead of the curve as it provides a sure connection with blockchain giants, ensuring its growth and development in the future. Unido will likely become a leader within the blockchain given the protocol’s current algorithm and products.

  • SushiSwap ($SUSHI) Explained

    SushiSwap ($SUSHI) Explained

    Before we begin

    We’ve been closely following the events involving SushiSwap and its founder “Chef Nomi”. This article will not be making any comments or conclusions on Chef Nomi’s actions or how SushiSwap is or should be run. This article is simply an explainer on what SushiSwap is and how to use the platform. As with all yield farming projects, SushiSwap involves a huge amount of risk. Anyone intending to participate in yield farming should do full research and consider carefully the risks involved beforehand.

    What is SushiSwap ($SUSHI)?

    SushiSwap is the newest decentralised finance (DeFi) liquidity pool platform. With SushiSwap, people can add their tokens into the liquidity pools and earn. In this article, we’ll have a look at the Sushi Swap platform and how to participate in the liquidity pool. Anyone can participate.

    Sounds interesting? Let’s dive into it.

    Summary

    • SushiSwap is a platform that allows anyone to provide liquidity. In return, the person gets rewarded with token(s) and SUSHI tokens. 
    • As of September 4, 2020, there are 1 billion dollars of locked liquidity.
    • Possibility of very high APY (up to 1,000%) on some liquidity pools. You can check the current yields on SushiBoard.

    Why is SushiSwap so popular?

    Sushi Swap markets itself as an “improved and community-friendly” Uniswap. Unlike a traditional exchange like Binance where they employ market makers, SushiSwap is a community-oriented platform where users provide liquidity. In return, they get rewarded. Indeed, the users are the market makers.

    SUSHI token

    SUSHI tokens are given as rewards for liquidity mining. The token allows its holders to participate in the governance of the platform and entitles them to a portion of the fees paid to the protocol by traders. For the governance of the platform, SUSHI holders can submit a SushiSwap Improvement Proposal (SIP) which token holders can vote on with their tokens.

    Of course, some people also speculate on the prices of SUSHI and the token can be traded on major exchanges such as Binance, FTX and OKEx exchanges.

    Advantages of SushiSwap

    There is no KYC (Know Your Customer) policy. This means anyone can trade and contribute to the liquidity pools. The platform is permissionless, meaning anyone can contribute millions of dollars without asking for permission. 

    Earn tokens from Sushi Swap. SUSHI is Sushi Swap’s native token. When you contribute to the liquidity pool, you earn sushi tokens. You can exchange SUSHI for ETH. 

    Sushi Swap model: 0.25% go directly to the active liquidity providers and 0.05% get converted back to SUSHI and is rewarded to sushi holders. 

    Sounds interesting? Let’s visit Sushi Swap’s home page.

    SushiSwap beginners guide 

    When you first arrive on Sushi Swap’s home page, you’ll see this:

    Click on “Unlock Wallet” or “See The Menu”, either way you will need to connect your ETH wallet in order to this platform. 

    Sushi Swap has the option to use MetaMask, WalletConnect or many other non-custodial wallets. Pick the one of your choice.

    Connect wallet
    Connect wallet

    Give permission for Meta Mask or Wallet Connect to connect to Sushi Swap. Once you’re connected, you’re ready to add your tokens into the liquidity pools. (hummingbirddental.ca)

    You’re presented with various liquidity pools (LPs). Each liquidity pool has a different annual percentage yield (APY).

    In this example, I’ll contribute to the ETH-USDT pool. I add my USDT into the liquidity pool. In return, I’ll get a percentage of USDT and SUSHI tokens. Think of Sushi Swap as a “community revenue share” model.

    To contribute to the liquidity pool, click “Approve USDT-ETH UNI-V2 LP” and give your Meta Mask permission to move your tokens into the liquidity pool. 

    Now what? You wait. The “SUSHI earned” box should populate with your earned SUSHI. You can withdraw your SUSHI token anytime by clicking on “Harvest”.

    2020 roundup and new roadmap!

    Many things have happened within the Sushiswap ecosystem in the last months: it is now time for a quick recap and to look at what the future will bring to this project!

    The number of all the partnerships finalized by the protocol is countless, but one of the most important ones, if not the most important, is certainly the merger with Yearn. The news also sparked controversies: Sushiswap was still considered a sort of “copycat” of Uniswap by some, and when Andre Cronje (Yearn’s father) wrote an article on how it is difficult to build in Defi and how conversely it is easy for anyone to just copy other people’s code, this wasn’t seen as really coherent. The collaboration was born to allow the two teams to cooperate on Deriswap.

    Nevertheless, Sushiswap has been evolving so much that, according to Mira Christanto (one of Messari’s data analysts) they have “put their past behind” and, not being backed by Venture Capitals, they can move faster than competitors. January has seen a real growth in Sushiswap’s TVL (now at $2.1 billion), mostly at the expense of Uniswap’s.

    Among the important milestones in 2020, we find Onsen, the new Sushiswap liquidity mining incentivization program which replaces the old Menu of the week. It brings communities together into the ecosystem and allows voted tokens to become accredited and participate in the mining program. The website also has a new layout of and a lite version.

    2021 Roadmap

    As the new year has already begun, it is also interesting to have a look at what Sushiswap is working on for 2021. The team released a long and detailed roadmap in early January. Notable upgrades are the following:

    • Mirin will be the new upgraded version of Sushiswap’s V3 protocol. It will include many new features like franchised pools, double yield, dynamic yield rebalancing, and many more as you can read here.
    • Bentobox (which should have launched in January) was born in the team’s mind as a new Lending Platform. While they were was working on its code though, it became something more. In simple terms, it will be a single vault that holds all tokens for any protocols and future extensions. It will support several oracles and it will also benefit all the $SUSHI holders.
    • Miso (Minimal Initial Sushi Offering) will be a sort of token launchpad, designed to drive new projects’ launches on the platform. It will include crowd sale options, IDOs (Initial Dex Offering), auctions, and more. We could think of it as something similar to Binance’s launchpad.
    • As Ethereum fees are and will keep growing in the next future until ETH2 will be a reality, most platforms are studying alternative solutions for their users such as Layer 2 possibilities. Unlike Uniswap, which is working on Optimistic Rollups, Sushiswap decided to move in sync with the greater Yearn ecosystem and thus will probably offer Zk-rollups options.

    Together with all these big news, Sushiswap is also planning to move to a new domain as the old one, in their view, is not enough to describe the diversity of the platform anymore. A transition to a fully decentralized governance structure is also planned by the end of 2021. Last but not least, Sushiswap has created a proposal page for people to express their ideas on what they would like to see on the platform. Everyone can be a chef is the place where you can voice your opinion if you like to suggest new ideas.

    FAQs

    Is it risky to provide liquidity to SushiSwap?

    The pool could get hacked if the code isn’t audited. There have been cases of hackers draining funds from smart contracts. It helps if the code is audited by a reputable firm. In the case of SushiSwap, it has been given a “security review” (not an audit) by Quantstamp. 10 issues were identified but they do not appear to be fatal. Subsequently, Peckshield had completed an audit on SushiSwap. They found no critical or high severity issues relating to business logistics but 2 high severity opsec issues that need to be fixed through extra care with deployment.

    What is the reward model of Sushi Swap?

    0.25% go directly to the active liquidity providers and 0.05% gets converted back to sushi and is distributed to active SUSHI holders.

  • Litentry ($LIT): Decentralized Cross-chain Identity Aggregator

    Litentry ($LIT): Decentralized Cross-chain Identity Aggregator

    Litentry ($LIT) is a decentralized cross-chain identity aggregator, built on Substrate, that features an identity matching and identity staking mechanism.

    In today’s world, personal data and identity are everything. Some companies in the conventional world make millions by selling user data. In the decentralized world, blockchain-based firms make losses.

    For example, one user can create multiple accounts to take advantage of free airdropped tokens. Also, platforms powering decentralized finance (DeFi) have no way of tracking users’ credit history, making them charge higher collateral when issuing loans.

    Fortunately, there’s a new way to keep track of identities in the distributed ecosystem securely. Powered by Litentry, we can see blockchain-focused platforms do more than just power token swaps. It’s now possible to scan through user’s deposit and withdrawal actions on Uniswap. Furthermore, a user’s activity can also be assessed on a community-governed blockchain.

    Since the platform is so diverse, below, we look at the major highlights.

    Background

    Litentry is developed by a team of blockchain professionals based in Germany. Its founder was among the early contributors of Parity, a decentralized network. Notably, the project engineering team’s background is rooted in Ethereum.

    The protocol is funded through a Web3 Foundation grant. On its Github page, the project lists eight team members with organization permission.

    What is Litentry?

    The project focuses on decentralized identity (DID), allowing user identities to be linked to multiple distributed protocols. Litentry acts as a DID aggregator where it collects, indexes, and distributes DIDs to blockchains.

    More importantly, it performs all these activities in a decentralized and verifiable way. Notably, built on the Substrate network, the platform works towards the greater goal of eradicating identity redundancy in the Web3-powered application ecosystem.

    The problem

    In the current internet world, third parties take control of storing user passwords and data pertaining to their online activity. Unfortunately, internet users are coerced into accepting unfavorable terms and conditions, consequently lessening the grip on their personal data.

    Litentry brings the change by returning the control of user data to the users by powering a user-focused internet using blockchain technology. As such, the revenue emanating from using users’ data gets the users to share in the profits. Before Litentry, these profits went to third parties managing the user data.

    Key Features of the Litentry platform

    Apart from using decentralized ledger technology (DLT), the platform has other critical features that help it bring the much-needed revolution to the blockchain sector. Key among them include:

    1. Identity management – The platform is all about identities, and their management sits at the protocol’s core. This feature powers anonymous and independent identities emanating from applications and or services used by the user.
    2. Distributed storage – After collecting the data, the protocol stores them in a decentralized manner to enhance access from all corners of the distributed world.
    3. Identity staking – This is a unique feature. Just like staking tokens and earning rewards, Litentry enables users to stake their identities and be rewarded.
    4. Decentralized contributors – Instead of creating multiple accounts to use different platforms or services, the project allows users to use one identity to interact with various services anonymously. Interestingly, the user doesn’t have to provide passwords or any other registration details.

    Litentry Architecture

    Litentry Architecture (Source: Litentry Doc)

    To bring all the above features to life, the protocol uses a layered architecture. On the top layer is the Litentry Runtime, which sits on Substrate. The Runtime layer is a Parachain of Polkadot and employs offline workers when generating identities.

    The second layer is the User Side. Here, users flex their muscles when it comes to data under their control. Note that user data that comes from applications are anonymous, stored in a decentralized way, and cryptographically-separated.

    On the Litentry Authenticator layer, we have the mobile data hub. The hub can be used to manage a user’s different identities. Additionally, the hub can be connected to various IoT devices that the user wants.

    Next is the Litentry SDK enabling developers to fire up their creative juices to create completely decentralized applications and/or services. In addition, the Litentry IPFS data center offers users a chance to check the data attached to their identities.

    The middleware layer comprises services such as off-chain catching and query servers. It is also made up of a client-side SDK library that helps connect front-end apps with decentralized networks.

    Litentry Tokenomics

    The incentive mechanism on the Litentry platform takes into account different participants such as an identity staker, validator, external storage, node, and data buyer.

    1. Identity staker — This is the person who has an identity record and has a stake in the identities pool.
    2. Identity validator — An identity staker becomes a validator of new blocks when their identity has been confirmed.
    3. Storage — Stores all data about an identity in a decentralized manner.
    4. Node — The node is a critical component of the Litentry platform. Its work is to perform functions such as invoking off-chain workers to validate identity correctness and connecting with external decentralized storages.
    5. Data buyer — This is any entity on the blockchain that requests identity validation.
    6. Data generator — These are entities generating data and can include applications, users, or services offering migration services.
    Litentry Tokenomic (Source: Litentry Lightpaper)

    Litentry Native Token (LIT)

    Litentry’s base asset is called LIT. The network uses the asset to reward identity stakers in the identities pool. Two types of rewards the stakers get are the block reward and the matching fee.

    Apart from stakers, validators are motivated to truthfully verify the correctness of data. On the other hand, data generators enjoy benefits from the Litentry Foundation in the form of grants.

    External storage operators earn a section of the fee paid by users interfacing with the service. Others who are incentivized using LIT tokens are nodes.

    Those who pay using LIT tokens include identity buyers. Observe that these entities only have access to the winning identity or identities during an identity matching process.

    Conclusion

    The identity problem is two-pronged; users can create multiple entities to defraud a company. On the other hand, malicious actors aggregate user data and sell it to the highest bidder without profiting the real data owners.

    Fortunately, Litentry uses a layered approach to comprehensively tackle the problem to the benefit of both identity owners and decentralized platforms. Here’s to another promising project with a unique approach to solving some of the most crucial problems that often go overlooked.

  • XFai ($XFIT): Can it resolve the liquidity and gas fee issues in DeFi?

    XFai ($XFIT): Can it resolve the liquidity and gas fee issues in DeFi?

    XFai is a decentralized oracle service provider that aims to address liquidity and gas issues in decentralised exchanges (DEXs) through a so-called DEX Liquidity Oracle which will revolutionise cryptocurrency trading whilst reducing gas fees.

    If you are a regular DEX trader, you might notice that there are times when you can’t complete trades. This happens often with small-cap tokens that do not have enough liquidity. In this case, traders have two options, either to wait it out until there’s enough liquidity or to increase price slippage tolerance. But either way, it can result in huge losses on the part of a small-cap token holder.

    XFai wants to address this problem by empowering DEXs with liquidity that can be supplied to small-cap tokens. This equalizes the playing field for every single trader, allowing them to execute their strategy without having to shoulder massive costs just because a DEX might not have enough liquidity on any particular trading pair.

    Check out our interview with XFai’s Chief Scientist, Taulant Ramabaja.

    Background

    The problem with many DEXs today is liquidity. While liquidity pools and profit-generating DeFi systems like yield farming have offered revolutionary solutions in the last year or so, DEXes still face this concern. This leaves many traders vulnerable to huge price slippages and losses. And if the issue persists, cryptocurrency traders might be discouraged and go back to trading mostly on centralized exchanges despite having less options.

    This is what XFai worked is trying to solve.

    XFai, which was co-founded by Geoffrey Khan, was developed in order to deal with the problems hounding DeFi markets today. It has gained a substantial amount of support, garnering investments from companies like AU21 Capital, LD Capital, and Roger Ver, one of the earliest adopters of blockchain technology and the CEO of Bitcoin.com. It is also worth mentioning that they were able to generate over $3.8 million within the first 12 hours of their private sale.

    What is XFai?

    XFai is a decentralized oracle service provider with the aim of addressing liquidity and gas issues in DEXs through a DEX Liquidity Oracle (DLO). This means that the protocol’s role is not only limited to supplying data to price feeds and engaging with smart contracts, but is also capable of actively providing and managing token liquidity in partner DEXs such as Uniswap.

    The primary goal of the project is to support small cap tokens and token holders by establishing a system that helps them earn better rewards. In other words, the project seeks to help them gain as much in incentives as they can, just like how a holder of a large cap token does.

    DEX Liquidity Oracle

    XFai’s DLO is powered by the XFai smart contract, which allows users to stake small cap tokens that can later be supplied to Uniswap pools according to corresponding price ranges and existing orders. The biggest trades facilitated on Uniswap exchanges will be provided with the liquidity collected from the DLO.

    This does not just benefit large volume trades for small cap tokens, but also those who supply liquidity on the same tokens. They receive rewards when they do so as well. The good thing about DLO is that it does not require liquidity providers to supply all the assets supported in a liquidity pool. They can choose to simply supply a single token in a pool, which also mitigates the risks of impermanent loss on their end.

    What supports this function further is its real-time price feed from centralized exchanges. Furthermore, the liquidity from the DLO is easily accessible to DEXs, addressing the issue on price slippage. This is exactly the goal of the XFai team, to support the current DEXs in the market and not to present itself as a competitor.

    How Does XFai Work?

    First, the user has to add tokens on the DLO liquidity vault/pool. The DLO is governed by a smart contract that also sends the tokens to partner DEXes when liquidity is needed. Note that users do not need to supply multiple assets at a time anymore, thereby reducing their exposure.

    Second, the DLO looks into the data from existing order books from other exchanges to determine existing prices and trading volume. Then, it comes up with a synthetic curve which they will use in order to pair DLO liquidity with partner DEXs.

    Then, there is a smart contract that governs how and when liquidity is supplied to a DEX using the synthetic curve. The goal of the contract is to ensure that enough liquidity is met by AMMs in order to avoid price slippage while allowing small cap token holders to supply liquidity without incurring impermanent loss.

    XFIT Token

    XFIT token is XFai’s native, utility token, which can be used as a medium of exchange, store of value, and means of payment for transaction fees. But more than that, it also has governance and reward functions. Liquidity farming is accessible in XFIT and all other DLO pairs.

    To start liquidity mining, holders can stake their tokens in select pools to earn proportional rewards. Each time the DLO profits from the trades conducted by its platform users, token holders earn additional XFIT. They can either redeem XFIT tokens to be later sold to the market, or they can decide to return their rewards back to liquidity pools in order to increase their stake position.

    In addition, XFIT token holders are also entitled to discounts on transaction fees if they use XFIT. They can also make direct swaps from XFIT to any other token in the protocol as long as they are supported by the DLO.

    XFai Liquidity Generation Event: How to stake XFIT

    The XFai liquidity generation event is a way to allow users to become involved with XFai’s XFIT token early, and stake them in the liquidity pool in order to earn increased, sustained yield throughout the launch period.

    To participate, users can go on the XFai website and click on “Farm”, then choose your preferred pool. Note that the APY is synced for all pools so they earn the same amount of APY as each other. Then click “Connect Wallet” to connect using MetaMask, once connected the dashboard will automatically calculate how much XFIT you can purchase with the amount in your wallet. Select the amount you want to stake and hit “Farm”.

    Whilst farming, you have the option to either Add to Farm, which allows you to increase your stake or Harvest, which allows you to claim your XIFT rewards.

    To claim your rewards, click “Harvest” and you would be presented with the option to Harvest XFIT or Harvest XFIT and unstake. Harvest XFIT allows you to claim the XFIT tokens gained into your wallet whilst keeping the staked amount in the liquidity pool to keep farming more XIFT rewards. On the other hand, Harvest XFIT and unstake means you can claim your XFIT rewards and unstake the staked amount (or any part of it) from the pool.

    The XFai LGE will be from 16th April to 7 May 2021.

    Conclusion

    Perhaps one of the largest factors that stop people from completely shifting their cryptocurrency trading activities to DEXs is the liquidity problem, apart from the fees. It is difficult to execute trades with low liquidity and even if they often do, sometimes, it takes multiple slippage tolerance adjustments before a trade gets to be completed.

    While this can look trivial for some people, this is something that can’t be neglected. If XFai takes off, the DeFi space might experience a better market situation. If traders do not have to be burdened by price slippages and if liquidity further improves through the same solutions the XFai team did, DEXs can be even more alluring to everyone, which would help speed up adoption.

  • Best Crypto Savings Accounts 2022

    Best Crypto Savings Accounts 2022

    Let’s be honest, traditional banking methods are starting to lose their value. Brick-and-mortar banks are paying disappointingly low rates on savings accounts these days. So if you want a higher return for lending out your money, it might just be the right time to explore alternative routes to engage your idle cash.

    More and more investors are exploring the advantages of cryptocurrency savings accounts. A crypto savings account allows you to enjoy the benefits of an old-school savings account but with the growth potential of cryptocurrencies.

    In this guide, we will explore some of the best crypto savings accounts for you to earn interest with your crypto assets.

    What is a Crypto Savings Account?

    The concept of crypto savings accounts are similar to traditional savings accounts. You put crypto assets into your crypto savings account, which are then lent on your behalf by a third party. The difference with a traditional account is that instead of dealing with fiat currency you will keep your funds in the cryptocurrency of your preference. 

    If you are looking for high returns but don’t want the risk of volatility in cryptos like Bitcoin or Ethereum, you can also choose to earn interest on stablecoins that offer high rates with more stability. Stablecoins are fixed to the value of the US dollar so you will not be exposed to cryptocurrency price fluctuations. 

    The best crypto savings accounts offer up to 12% interest on stablecoins and lets you earn 6% interest on popular assets like Bitcoin and Ethereum.

    What are the Best Crypto Savings Accounts for 2022?

    With so many players in the market, it may help to compare crypto interest rates side-by-side before deciding on where to put your money. That being said, high interests should not be the only consideration for choosing a crypto savings account. Some other factors to consider are supported coins, compound interest, loan-to-value rates, withdrawal restrictions, transaction fees and security. You should always choose a platform that best fits your needs.

    Let’s have a look at some of the best and most trusted crypto savings account providers for 2022.

  • Understanding Layer 2 & Scaling Solutions: Arbitrum, Boba, Optimism, Polygon, Ethereum 2.0

    Understanding Layer 2 & Scaling Solutions: Arbitrum, Boba, Optimism, Polygon, Ethereum 2.0

    One of the core problems with the Ethereum network today is scalability. As more and more decentralized apps (dApps) are built on the network, the number of users and transactions increases. This has slowed down the speed of transactions and driven up the cost of using the network, creating the need for scaling solutions.

    At its full capacity, the Ethereum network is only able to process 15 transactions per second. To put Ethereum’s scaling limits into perspective, consider that Visa handles around 1,700 transactions per second on average. Therefore, increasing the network capacity in terms of speed and throughput is fundamental to the meaningful and mass adoption of Ethereum.

    There are multiple solutions being researched, tested and implemented that take different approaches to achieve similar goals. Two solutions that we will explore in this article are known as sidechains and optimistic rollups.

    Check out our explainer video on layer 2 solutions such as Arbitrum, Boba, Optimism, and Ethereum 2.0

    Layer 2 solutions explained (Arbitrum, Boba, Optimism, Ethereum 2.0)

    What is Layer 2 and How Does it Work?

    The Ethereum main chain is known as Layer 1. Layer 1 applications and smart contracts interact directly with the native chain. Layer 2 refers to a series of different protocols that facilitate the creation of smart contracts and decentralized applications (dApps) on top of the core Ethereum blockchain.

    Operating on Layer 2 frees up Layer 1 by taking transactions off the main chain, offloading it to Layer 2, enabling them to interact, and then recording the remainder of the whole transactions back to Layer 1. Due to transactions being processed off-chain on Layer 2, Ethereum benefits from higher transaction processing capacity, faster confirmation times, and lower gas fees. 

    In fact, many believe that Layer 2 solutions will be how Ethereum wins over mainstream users. It is estimated that 2,000 – 4,000 transactions per second can be processed in Layer 2, which is already in line with Visa’s processing capabilities. By combining the scaling of Layer 1 with Ethereum 2.0 and Layer 2, Ethereum is set to obtain a powerful economic bandwidth.

    Sidechains: Polygon Network

    Sidechains are a Layer 2 solution utilizing separate blockchains that run in parallel to the Ethereum main chain but operate independently, hence increasing its scalability. 

    Polygon is the most popular sidechain that aims to scale Ethereum by building and connecting Ethereum-compatible blockchain networks. Polygon operates on its own consensus mechanism and also has its own native token known as $MATIC.

    Because sidechains run on a separate blockchain, they do not inherit the security of Layer 1. If a sidechain is hacked or compromised, the damage will be contained within that chain and will not affect the main chain. Conversely, should the main chain become compromised, the sidechain can still operate.

    Sidechains also provide room for a lot of flexibility, allowing developers to experiment with new features or software updates before pushing them onto the main chain.

    Rollups Explained: Optimistic Rollups & Zero Knowledge Rollups

    Rollups are another Layer 2 solution intended to solve Ethereum’s scalability and complement the network. Rollups interact with the main chain, therefore inheriting Layer 1’s security features as well as its secure consensus mechanism. The term ‘rollup’ refers to the way that the chain bundles many transactions to be submitted to the main chain.

    Because rollups use smart contracts that reside within Ethereum, they do not require a native token like Polygon, but instead use $ETH as their currency. Rollups seem to be the most sound scaling solution for Ethereum as it does not compromise the security and sovereignty of Layer 1.

    There are basically two types of rollups: Optimistic Rollups and Zero Knowledge Rollups (ZK Rollups). Both aim to scale Ethereum by processing transactions on Layer 2 before submitting the results back to Ethereum. However, the difference is in how they validate transactions. 

    In simple terms, Optimistic Rollups assume that transactions are valid — hence an optimistic outlook. However, it also allows what are called “watchers” to call out fraudulent transactions since blockchain is transparent and public. If a watcher proves instances of fraud, the transaction is reverted, the bad actor penalized, and the watcher rewarded to incentivize them.

    On the other hand, Zero Knowledge Rollups attempt to prove that transactions are valid. They do so by submitting validity proof to an Ethereum smart contract along with the bundled transactions.

    Optimistic Rollups are currently the more popular option, so let us look at some projects that have adopted this mechanism. These projects are Arbitrum, Boba, and Optimism.

    Optimistic Rollups: Arbitrum, Boba & Optimism

    Arbitrum, Boba and Optimism are 3 projects which have the same goals of scaling Ethereum and reducing gas fees. All of these Layer 2 projects are competing with one another to be the best network. Therefore, each project offers different features to stand out from the others.

    • Arbitrum describes itself as a Layer 2 solution designed to improve the capabilities of Ethereum smart contracts — boosting their speed and scalability while adding additional privacy features to boot. Arbitrum is, according to the team, around 90-95% cheaper than Ethereum. And with their Nitro being launched soon, they expect costs to be cut even further.
    • Optimism is an EVM-compatible Optimistic Rollup chain designed to be fast, simple, and secure. Optimism pledges to uphold the values of Ethereum by producing infrastructure that promotes the growth and sustainability of public goods.
    • Boba Network is a next-generation Layer 2 scaling solution that reduces gas fees, improves transaction throughput, and extends the capabilities of smart contracts, shrinking the Optimistic Rollup exit period from seven days to only a few minutes, while giving liquidity pools (LPs) incentivized yield farming opportunities.

    Arbitrum’s fraud proofs seek to find the particular point of disagreement over transaction history. In contrast, Optimism’s tech looks at fraud a bit more holistically. And this means that Arbitrum has a higher transaction capacity equating to higher performance.

    Optimistic Rollups have a time period in which users can dispute transactions and call fraud. Both Arbitrum and Optimism allow one week for that dispute period, which means that transactions in a bundle under suspicion can be held in limbo for one week before they are verified and released. This is where Boba comes in as a serious player. 

    Instead of having funds locked for several days, Boba’s solution brings the dispute period down to only a few minutes. It also provides incentivized yield farming opportunities, both serving as very attractive features in comparison to its competitors. 

    Will Ethereum 2.0 Make Layer 2 Solutions Irrelevant?

    Ethereum 2.0 is regarded as the long-term solution that can bring speed, efficiency, and scalability to the Ethereum network. The long awaited upgrade will move the network from a Proof-of-Work consensus to a Proof-of-Stake consensus, a much more energy efficient method of maintaining the network that uses validators instead of miners.

    Ethereum 2.0 is currently slowly being released in different phases and will ultimately speed up transactions as well as drastically reduce the cost of gas fees. That brings up the question: Will Ethereum 2.0 make all these Layer 2 solutions irrelevant?

    While there are many different opinions and discussions surrounding this topic, however, we think that all of these solutions can coexist and benefit the network as well as its economy.

    This is because despite the upgrade, Ethereum 2.0 may still not be able to handle the amount of transactions per second required for widespread adoption. The impressive capabilities of Layer 2 solutions could eradicate Ethereum’s scalability issues for good, allowing the network to improve other aspects and prevent congestion on the main chain.

    Final Thoughts: Why Are So Many Solutions Needed?

    There is no debate that Ethereum has a stronghold over developer mindshare. It is the first network that enabled developers to build truly unstoppable decentralized applications with global distribution from day one. But competition is coming fast, and as it stands today, Ethereum will not be able to handle the scale necessary for millions of users. If the network wants to retain the same level of decentralization, it will have to look for new ways to structure use around the main blockchain. 

    As such, there are currently several Layer 2 solutions that aim to resolve Ethereum’s scaling issues. There are also some hybrid solutions which seek to improve the network’s scalability by combining the technologies. But is there really a need for so many solutions?

    We say yes, because multiple solutions can help reduce the overall traffic on any one part of the network, and also prevent single points of failure. The whole is greater than the sum of its parts. Different solutions can exist and work in harmony, allowing for an exponential effect on future transaction speed and throughput. Furthermore, not all solutions require utilizing the Ethereum consensus algorithm directly, and alternatives can offer benefits that would otherwise be difficult to achieve.

    If Ethereum achieves its full potential of becoming a global trust layer, it is likely that these solutions and more will be required to scale the network in combination with Ethereum 2.0. In the future, the Ethereum ecosystem could see significant change as new projects assess the benefits and drawbacks of running on Layer 2. 

    If all of these solutions can come together in harmony, Ethereum will achieve a blockchain system that can match the speed and scale of programmatic advertising – one that can be used by industries with high data processing needs as well as users worldwide.

  • What are “Money Legos” in DeFi? Composability Explained

    What are “Money Legos” in DeFi? Composability Explained

    What is Composability in DeFi?

    Decentralized finance (DeFi) has revolutionized financial services, creating new possibilities unlike anything that exists in traditional banking. DeFi protocols allow you to transfer value, exchange tokens, take out loans, provide liquidity, earn yields and so much more. As the market expands, it is likely that even more innovations will surface.

    This is because of how smart contracts work. The open-source and permissionless nature of blockchains allows anyone to code their own contracts or even integrate a component of another protocol in their own application. As a result, the applications built on a smart-contract network can run interchangeably.

    This is known as “composability” — the interoperability of DeFi protocols resulting in efficient and creative financial services and products for users. It is the core basis of DeFi and is what helped the ecosystem grow so quickly.

    What are “Money Legos” in DeFi?

    To understand how composability works in DeFi, we can view components of DeFi protocols as Lego blocks, giving rise to the term “money legos.” Each building block has its own functionality such as borrowing, lending or staking assets, just to name a few. Developers can stack multiple protocols together like Aave, Compound, Yearn, Curve or Synthetix to create a new DeFi protocol, just as you would a Lego set.

    For developers, money legos save a lot of time and complications around building a new decentralized application (DApp). They do not need to start from scratch as they can simply integrate existing money legos into their own. What money blocks provide are solutions to more complex processes which require more steps than usual.

    Moreover, developers can build smart contracts that can operate the legos in any order, be it one before or after the other, or in parallel. For example, by joining the money legos together and then specifying the order of events through a smart contract, users could

    1. Put up collateral for a loan on Aave
    2. Stake half of the loaned amount on Curve
    3. Trade half of the loaned amount on Uniswap
    4. Pull out both amounts simultaneously and take profit
    5. Pay off the loan on Aave

    This is just one type of scenario. As you can see, there are infinite possibilities with money legos. It is up to your creativity how much use you can make of the combination of their functions to optimize your crypto. Furucombo is a great platform to experiment different possibilities of DeFi money legos.

    Why “Money Legos” Matter?

    “DeFi” is a buzzword that gets thrown around a lot. People often associate DeFi with low fees and yield farming, but do not exactly know how the underlying infrastructure works. Therefore, it is important to learn about money legos as they are the building blocks for programmable money, hence its name. While developers can compare and choose specific DeFi protocols to cut down on fees when building new applications, investors can better optimize and manage their crypto by having a better understanding of money legos.

    As savvy investors, we know that key performance indicators (KPI) of a healthy market and ecosystem are trading volume and activities. As such, money legos are powerful tools that can expand the potential possibilities of the ecosystem. They add to the utility of each existing protocol, while improving the blockchain’s network effect.

    In other words, each time a new protocol is created in the DeFi space, a new money lego is born that can also be used to offer more new services within the sector. These new protocols will offer faster and more efficient services, giving investors more ways to generate profit. For each new money lego, hundreds or thousands of new combinations become possible.

    However, as of now, composability mostly favors protocols of the same blockchain. For example, DeFi protocols on Ethereum can only interact with other protocols on Ethereum. Same goes for Solana or Cardano. Perhaps in the future, true multi-chain interoperability will allow protocols on one blockchain interact with a protocol on another blockchain. This means that crypto will become more accessible, further increasing their adoption.

    Risks of “Money Legos” Composability

    Since DeFi protocols can seamlessly integrate with each other, this means that the entire ecosystem hinges on each of its money legos. If one of the core money legos is compromised, it could lead to a chain reaction, potentially affecting other integrated applications.

    This is possible because of the interoperability between the DeFi protocols. For example, you can carry out complex strategies like borrowing Synthetix (SNX) from Aave, depositing SNX into Synthetix to mint sUSD, then swap sUSD for DAI on Curve. Now if any one of these protocols is attacked, then all of their liquidity pools will be severely affected.

    Moreover, certain protocols also have wrapped crypto tokens (e.g. WBTC, renBTC, wETH) that are pegged to the value of another crypto. This means that you not only have to trust the protocol you deposit your funds to but all the others it may be reliant upon.

    Key Takeaway

    It is important to understand money legos as they are the building blocks of the DeFi ecosystem. Money legos help developers create new protocols, offering faster and more efficient financial services for DeFi end-users. It also helps investors get the best trades and the best yields when it comes to earning from DeFi protocols. That is the whole concept behind the idea of composability. Seamless interoperability among components helps to build the best and most creative solutions.

  • Crypto war- The role of cryptocurrencies in the Russian-Ukraine conflict

    Crypto war- The role of cryptocurrencies in the Russian-Ukraine conflict

    Crypto: The Power of Memes

    On Feb 24, on the same date Anton Drexler founded what would become the Nazi Party, Russian President Vladimir Putin ordered a full-scale invasion of Ukraine. As Moscow’s bombs dropped on the country’s major cities, the nation’s Minister of Digital Transformation Alex Bornyakov fled its capital city of Kyiv.

    Check our our video discussing the implications of the invasion of Ukraine on cryptocurrency:

    Ukraine Invasion: Implications for cryptocurrency?

    Two days later, Bornyakov’s boss, Ukrainian vice premier Mykhalio Federov posted Bitcoin and Ethereum wallet addresses over Twitter, requesting crowdsourced crypto donations.

    “We start to accept donations in meme coin. Now even meme can support our army and save lives from Russian invaders,” said Fedorov on March 2.

    Doge Army

    According to data tracked by the blockchain analytics firm, Elliptic, the majority of donations to Ukraine have been paid in Ether and Bitcoin, but donors have also sent the PolkaDot cryptocurrency as well as stablecoins like Tether.

    “We’re watching history being made in real-time here,” says Braintrust Network co-founder Adam Jackson.

    According to Crypto for Ukraine, over US$100 million in cryptocurrencies have been donated to Ukraine. The number is currently growing. Of the donations, nearly 40% were in Ethereum, followed by 31.51% in Bitcoin.

    A report by Yahoo! Finance states that the split of funds starts at 69% going to military support, 19% for humanitarian aid, and 12% for general aid as of the time of the report on March 8.

    Bornyakov thinks that in times like the current crisis, response time is crucial.

    “The National Bank of Ukraine created a fiat fund, but with the time and speed of a regular banking system, it was impossible to finance important things for the army. Crypto plays a role to get this flexibility when we really needed to respond quickly to deliver the army with its required supply,” Bornyakov said.

    Cryptocurrencies offer much faster transaction times, but not all businesses accept them as payment, according to Bornyakov. Currently, the government converts the donated crypto assets into dollars or euros through Ukrainian exchange Kuna, which it has partnered with to also custody the funds. 

    This helps reduce the friction arising when crypto donation funds are used to acquire goods for the military in order to fight off Russian forces.

    Some firms do in fact accept crypto, but for those who do not, cryptocurrencies are sent via the exchange into the conventional banking system for payment.

    Ettore Rosetti, the digital, marketing and innovation lead advisor for NGO Save the Children said that the group is seeing millions of USD in pledges in crypto projects. The humanitarian group has accepted crypto contributions since 2014, but the range is more varied now, accounting for the expansion of the crypto world.

    “You’re crowd-sourcing a humanitarian effort in real-time,” said Jackson.

    “What’s fascinating about the emerging currency types are NFTs. We’re getting inquiries from artists wanting to create an NFT to benefit Save The Children’s response in Ukraine,” said Rosetti.

    Indeed, Crypto Punk NFTs worth USD200,000 form part of the contributions to Ukraine’s national crypto aid fund opened on Feb 26. And Russian protest punk band Pussy Riot’s co-founder ​​Nadya Tolokonnikova organised an auction fundraiser to sell an NFT of the Ukrainian flag for USD7mil.

    Amid the geopolitical and economic turmoil that has come about due to the Russia-Ukraine crisis, a sense of a real impact being made seems to stand out. Never in the history of the highly linked phenomena of war and economics have we seen the impact of ordinary citizens come about so quickly. 

    Days before the Russian invasion, Ukraine legalised cryptocurrency after 272 of its 450 parliament members voted for the move. Then, according to a Vox article by Emily Steward and Rebecca Heilweil, some Ukrainians also turned to crypto as an alternative to Ukrainian financial institutions, which had been limiting people’s access to bank accounts and foreign currency amid the crisis.

    Now, Ukraine ranks 4th in the world in crypto adoption, according to research firm Chain Analysis.

    In Putin’s Russia, Crypto Exchange You

    Meanwhile in Russia, a report on ABC11 states that as Visa and Mastercard suspended their services and sanctions on the economy began to take effect, many are turning to cryptocurrency as well.

    Ordinary Russians are now using crypto as a lifeline as their currency collapses under the brunt of geopolitical economic reprisal, according to Coinbase Global CEO Brian Armstrong.

    “Many of them likely oppose what their country is doing, and a ban would hurt them, too,” wrote Armstrong over Twitter just before midnight on March 3.

    “If the US government decides to impose a ban, we will, of course, follow those laws,” added Armstrong.

    Binance CEO Changpeng Zhao, the world’s largest crypto exchange, mirrored Armstrong’s sentiment but was more ambivalent with his stance on the conflict.

    “Should a coffee shop in Paris refuse to serve a Russian customer? Or take their wallet while they’re at it? The answer to that is no,” he wrote in a blog post. “We are not going to unilaterally freeze millions of innocent users’ accounts.”

    One issue driving the push towards crypto sanctions on Russian users is that nations are wary of the nation’s oligarchs and Putin’s real resource of power might use it to evade sanctions. As it stands, steps had already been taken by these oligarchs to secure their wealth amid threats from the US and its allies, particularly a US task force created for this specific purpose announced by US leader Joe Biden on Feb 27.

    On February 28, superyachts owned by Russian billionaires linked to President Vladimir Putin were on the move as the United States and its allies prepared further sanctions on their property following the invasion of Ukraine.

    However, US Treasury deputy secretary counselor Todd Conklin has suggested crypto can’t be used to fully circumvent the sting of sanctions, given its practical limitations.

    “Crypto is traceable, transparent. If someone is sending Putin Bitcoin from outside of Russia to evade US sanctions, then chances are they had to buy that bitcoin at an exchange and that exchange has their name,” added Jackson.

    “While technically it could be used to avoid sanctions, it’s not a great way to do it,” he adds.

    And as every transaction of the blockchain is transparent and public, cryptocurrency exchanges can use the information to trace the source of the funds to see if it is coming from blacklisted or sanctioned sources. In turn, the exchanges can also identify and block sanctioned persons from even opening an account.

    US Financial Crimes Enforcement Network acting director Him Das said in a statement on Monday that the agency had “not seen widespread evasion of our sanctions” via cryptocurrency.

    As it stands, analysts say wealthy and well-connected Russians often have a web of front companies through which they sift funds and crypto might not form a large part of this web.

    According to The Washington Post, Trump-era Treasury Department assistant secretary Marshall Billingslea said that “the oligarchs have so many well-heeled accountants and complicit bankers around the world, they don’t really need to go that way. And if they’re investing in sound sanctions advisers, they’re being warned that some of these blockchain currencies like Bitcoin are not nearly as opaque as they might have thought,” somewhat reflecting what Jackson said above.

    Large-scale avoidance of sanctions by say, turning fiat into cryptocurrency would prove difficult. For example, if an oligarch wanted to convert $1 billion dollars into cryptocurrency, they would find it very difficult since there is insufficient liquidity in the market to convert such a large sum. The oligarch would have to use multiple exchanges which would make the process extremely inefficient.

    But avoiding sanctions using crypto could happen at a smaller scale over a longer period of time. As Investors.com states, Iran and North Korea offer some shady guidance to the world of discreet digital asset fundraising.

    Crypto and blockchain analysis firm Elliptic found that Iran has used Bitcoin mining to bypass US embargoes, using Bitcoins their computers mined to pay for imports that would have otherwise been sanctioned. North Korea meanwhile employed hackers to steal some USD400mil in assets from cryptocurrency platforms last year, according to the research firm Chainalysis.

    Russia’s embargoed but wealthy persons of interest could also channel divert money through smaller crypto exchanges that seem legitimate but have dubious compliance protocols under closer scrutiny. These exchanges might even be cooperating with the person of interest or their group’s money-laundering or ransomware schemes. The US last year sanctioned two exchanges on allegations of facilitating ransomware transactions.

    Ironically, the failure to prevent Russian oligarchs from using crypto to squirrel away their millions around the world might force tighter regulations on cryptocurrencies themselves, putting proponents of crypto as a fair and balanced force for economic good, particularly during the Ukrainian conflict, in a bit of a moral dilemma.   

    As Forex.com global head Matt Weller was quoted at Investors.com said: “Those are the main two competing factors: The ideological-utilitarian perspective on the benefits of crypto assets versus the financialized investment component. Those are sort of pushing in opposite directions.”

    One situation that really highlights a potential irony in this dilemma is Pussy Riot co-founder ​​Nadya Tolokonnikova. That she is trying to help Ukraine as a protest against Putin seems to fit in the current zeitgeist of the conflict. But as Russian, imposing sanctions against Russian crypto to help Ukraine would stop her from raising money for Ukraine.

    As the saying goes, the road to hell is paved with good intentions.

    Those Are Blood Money

    For Ukraine, they don’t have a choice in deciding how to balance the scales of this dilemma between economic fairness and moral-geopolitical good. As far as they are concerned, blind-but-fair adherence to crypto’s anonymous invisible hand of the market means their people will die.

    Bornyakov’s ministry has started to reach out to major exchanges to not work with Russia for the time being because as he puts it: “They use this money to kill civilian people, to invade a free country without any reason. We inform those exchanges with official letters, with calls, where we can reach to stop work with Russia. Because those are blood money and in many cases come from corruption.”

    According to the minister, some exchanges have stopped while others have limited their activity with Russia, and some working with Russia have been blocked, indicated by their complaints on social media.

    Outside of the US raising sanctions, the most likely situation to happen in the next few months is that certain high-risk exchanges that don’t comply with regulations, at least in the United States, will be sanctioned by the Treasury Department in the near future, according to digital asset risk assessment firm TRM Labs’ legal and government department leader Ari Redbord.

    “Because there is no central controller who can impose their morals on its user, crypto can be used to crowdfund for the Ukrainian army or help Russia evade sanctions,” said Elliptic’s chief scientist and co-founder Tom Robinson to The Washington Post.

    “No one can really prevent it from being used in either way.”

    According to Investors.com, TRM Labs recently identified 340 crypto businesses with strong Russian connections that it considers high risk such as lesser-known over-the-counter trading desks.

    World’s First Cryptowar

    Since Sun Tzu wrote the Art of War, the economics of defence has been widely discussed by both governments and private businesses alike. That it is now crypto’s turn to take up arms or rescue the helpless should surprise nobody. 

    But for a virtual asset so decentralised and antithetical to concerns of the state, the speed at which it has been applied to wartime has to a degree taken many state actors by surprise.

    Both The Washington Post and Vox agree to some degree that war has pushed the utility of crypto to such a degree that the unique circumstances of war have made crypto itself a part of it.

    According to the Vox article, “What we do know is that bitcoin and other cryptocurrencies are now a real factor in global economies and in conflicts.” Meanwhile, The Washington Post has straight-up dubbed the Russia-Ukraine conflict “the world’s first crypto war”.

    What this conflict will do for the futures of individual cryptocurrencies is frankly anybody’s guess. But one thing we do know is that due to its unique attributes of speed and stealth, some of the most desirable attributes for any other tool or weapon, crypto’s role in the war is here to stay.

    Crypto becomes an invaluable asset to Ukrainian refugees

    Cryptocurrencies have been immensely valuable to Ukrainian refugees. As Russian attacks have destroyed critical infrastructure, many Ukrainians are finding it hard to withdraw cash from ATM machines. Therefore, many Ukrainian refugees are relying on digital currencies sent from relatives abroad in order to purchase goods and services. All that is needed for them to access their cryptocurrency wallets is a mobile phone and internet access, which is being provided by the thousands of Starlink satellite internet dishes provided by Elon Musk’s SpaceX.
