What is Yearn.finance (YFI) and how does it work?

One of the fastest growing DeFi projects, Yearn.finance has spawned a range of core products that provide passive earnings on crypto assets.

Launched in July 2020, Yearn.finance has emerged as one of the major players in the emerging decentralized finance (DeFi) space that provides services such as staking, lending aggregation and yield generation on the Ethereum blockchain. Boasting the most user-friendly crypto trading services that are being meted out autonomously, the project uses its native ERC-20 Yearn Finance (YFI) cryptocurrency to incentivize those who lock their crypto tokens in Yearn.finance contracts through any of the supported platforms such as Balancer and Curve DeFi.

With all of its protocols operating on the Ethereum blockchain, Yearn.finance is managed through developers that act in accordance with governance proposals voted for by YFI holders. Crafted with the vision of simplifying the process of investing in DeFi products, the Yearn.finance platform also offers its users the ability to invest in other DeFi protocols in addition to earning a percentage of the platform’s fees in proportion to their YFI holdings. 

Who is behind Yearn.finance?

A veteran of the cryptocurrency and DeFi space, Andre Cronje launched the Yearn.finance protocol without raising any funding either through public or private means. Instead, the software architect relied on his over two decades worth of software development experience to launch the protocol first and then issued YFI tokens to retail investors, which are currently limited to a maximum supply of 36,666 tokens. 

Apart from the extremely rare approach adopted by Cronje, the Yearn.finance platform has benefitted from his previous experience as the founder of the Keep3r Network and his association with notable DeFi projects that include the likes of PowerPool, Hegic, Cover, Pickle, Cream V2, SushiSwap and Akropolish, among others. Unlike other founders, Cronje didn’t reserve any YFI tokens for himself prior to the Yearn.finance protocol’s launch, believing that a truly decentralized blockchain technology-based platform should not have the founder hanging on and dictating its future course. 

In fact, the history of Yearn.finance can be traced back to his efforts over the past five years to launch cost-effective financial products for the unbanked segment of the world’s population and has been heavily influenced by his efforts in Africa toward achieving the same. By choosing to focus on creating value for the entire DeFi ecosystem of developers, partners and investors on the Yearn.finance platform, Cronje has provided scores of crypto entrepreneurs with a new perspective on how to build DeFi products for the masses. 

 What is Yearn.finance (YFI) and how does it work? 

Built on the Ethereum blockchain, the Yearn.finance protocol eliminates the need for a financial intermediary like a bank and offers crypto investors and tokenholders access to its range of lending and trading services that include Vaults, Zap, Earn and APY. The Yearn.finance protocol can deploy its smart contracts on the Ethereum blockchain as well as other decentralized exchanges that operate on it. Offered through a simplified web interface, Yearn.finance is a radical experiment in the DeFi world and has one sole aim- to maximize returns on crypto assets for its users. 

The most complex among its products is the Vaults product, which acts as a mutual fund of sorts and has 50+ different vaults or staking pools for Yearn.finance’s users to deposit their tokens in. These Yearn.finance vaults are basically investment strategies in other DeFi projects like Convex Finance and Compound Finance, with pre-programmed logic deciding when to shift capital and code automation deciding the yield generation and rebalancing process. Users additionally benefit from the lower gas costs and low transaction fees levied by Yearn.finance on each vault-related transaction.

The Earn product, Yearn.finance’s first product, relies on the interest rate changes on the Aave, dYdX and Compound protocols to let its users benefit from the best interest rates at all times. A lending aggregator, in principle, Earn allows Yearn.finance’s users to allocate their crypto tokens to either or all of these liquidity protocols and earn higher interest rates than that provided by traditional finance instruments. For those invested in stablecoins such as Binance USD (BUSD), USD Coin (USDC), Tether (USDT), TrueUSD (TUSD) or Dai (DAI), the Zap product enables them to swap between liquidity pools on the Curve Finance platform and deposit into any of Yearn.finance’s vaults using almost any token on a single click. 

How does “Earn” a lending aggregator works in Yearn.Finance

This results in not only cost and time savings but also simplifies the entire task as many individual trades are coupled with Yearn.finance’s coding. The platform also provides its annual percentage yield, or APY, tool that compiles the interest rates offered by the various DeFi lending protocols at a glance, thereby helping crypto investors in narrowing down on the right platform for further investing. 

What can you do with Yearn.finance?

The Yearn platform has something for everyone-investors, developers and even other DeFi projects that are interested in partnering with Yearn.finance. For crypto investors, the Earn, Zap and APY products help them to lend their crypto holdings or trade them for short-term yields, all in an effort to bolster their chances of earning a passive income. Zap and APY effectively improves the user experience when they use the Earn product, essentially a yield farming tool, to earn the highest interest rates across the Aave, dYdX or Compound lending protocols. 

The Yearn.Finance model

Vaults, on the other hand, introduces users to a revolutionary way of actively investing using Yearn platform’s self-executing code, mimicking how traditional mutual funds operate to extract the best return for their investors. By using the Yearn.finance platform to run its smart contracts on the Balancer and Curve DeFi trading platforms, users can enjoy all aspects of a yield optimizer without having to worry about the internal workings. In this way, Yearn.finance is also a DeFi yield aggregator, but with a design that is simple, intended to maximize investor returns and works for the benefit of all YFI tokenholders.

Written in the Solidity programming language, users with a fair knowledge of this language can even transparently see how the code for each vault invests the lent tokens further into different DeFi protocols. For developers, Yearn.finance offers the functionality of creating custom vault strategies that then undergo a peer review, testing in a production environment and going live once the Safe Farming Committee provides its approval. The Yearn platform details the various procedures that are needed to be followed by developers, including naming conventions and operating procedures for these smart contracts. 

For other DeFi projects, Yearn.finance has displayed a rabid enthusiasm for collaboration as the platform strives to build a DeFi future where everyone can access any service or protocol from anywhere. Furthermore, Yearn.finance joined forces with the layer-2 Optimism protocol in August 2022 and is an example of its inclination toward building cross-chain interoperability and working toward improving capital efficiency for its users.

Is Yearn.finance secure and is YFI a good investment?

By virtue of providing YFI tokenholders the right to vote on community-submitted proposals, Yearn.finance has all the trappings of a truly decentralized DeFi project that prioritizes the tokenholders’ interest above all else. Known as Yearn Improvement Proposals (YIPs), any member can start a YIP on Yearn.finance’s governance forum and if a majority number of the members support it, the YIP will be put ahead for official voting through the YFI governance staking model. 

All YFI holders are eligible to vote on these YIPs, whether it be about a new vault, changes to the governance mechanism or even suggesting changes to the current fee structure. However, as admitted by founder Andre Cronje, DeFi involves risk and had even quit the space briefly before getting back to launch the Yearn platform. That being said, despite all efforts to ensure that the Yearn platform functions transparently, users do face a moderate risk of facing losses caused by volatile market conditions. The YFI cryptocurrency too is subject to trading fluctuations, changing market sentiments and speculative activity by large institutional traders

That said, as has been seen with various blockchain projects that have been successful over a period of time, investors may choose to hold onto their YFI holdings to potentially benefit from long-term price appreciation. With the peak total value locked (TVL) in the Yearn.finance protocol reaching a high of $6.91 billion, the Yearn platform is counted among the fastest-growing DeFi protocols in existence. Considering the range of benefits it provides and the honest nature employed in its governance model, Yearn.finance can be counted among the most significant DeFi investment platforms to have emerged in the post-pandemic era.

This little-known DeFi crypto token has rallied over 800% in a month

While an ongoing technical divergence between BOND's price and volumes suggests upside exhaustion.

A new and relatively unknown DeFi token called BarnBridge (BOND) has rallied over 800% to reach $20 on July 26.

The BOND price surge comes more than a month after bottoming out at around $2.19. In comparison, top coins, Bitcoin (BTC) and Ether (ETH) have only rebounded by 18% and 54% in the same period, respectively.

Another pump and dump?

BarnBridge is a cross-chain risk management protocol that offers a suite of composable DeFi products for investors to hedge against interest rate fluctuations and price volatility.

Examples include SMART Yield — a product that enables investors to secure fixed rate yields from the debt pools of other projects such as Aave, Compound, Cream, or Yearn.finance — and SMART Exposure, which offers investors tools to rebalance portfolios.

BarnBridge SMART products explained. Source: Official Website

BarnBridge's latest product, SMART Alpha, allows investors to hedge against price fluctuations and provides them leverage for bullish theses. Meanwhile, BOND serves as a governance token to the Ethereum-based DAO representing BarnBridge.

On the surface, the latest BOND price pump should reflect a booming interest in risk-trenching protocols, primarily when many projects in the DeFi sector have failed. But the token's gains appear largely speculative if one focuses on its trading volume concentration.

Notably, more than 50% of BOND volumes have originated at Binance in the past 24 hours, according to data tracked by CoinMarketCap. At the same time, the daily trading activity of the benchmark BOND/USD pair has been declining during the price pump, as shown below.

The price-volume divergence suggests that fewer investors have been behind the BOND price pump, increasing the chances of a sharp correction in the coming days or weeks.

Next BOND price targets

Drawing a Fibonacci retracement graph from BOND's swing high of $37.50 to its swing low of $2.18 churns out a sequence of potential support and resistance levels, as shown in the weekly chart below.

BOND has been retreating after testing $24 as its interim resistance, and now anticipates to undergo an extended correction toward $15.60, down 17.5% from July 26's price. A further breakdown risks crashing the price to $10.50, or a 45% decline.

Conversely, a rebound above $24 could have BOND test $30 as its next upside target. Another breakout move could shift the target to $37.50, up 95% from current price levels.

3 red flags that signal a crypto project may be misleading investors

The challenges faced by Terra, Wonderland and a handful of other DeFi projects exposed the need for investors to do more research and avoid cult personalities.

Satoshi Nakamoto left a large pair of shoes to fill after releasing the code for Bitcoin (BTC) to the world, helping to establish the network, then vanishing without so much as a trace. 

Over the years, the crypto ecosystem has seen many developers and protocol creators rise in stature to become crypto messiahs for faithful holders who eventually have their best-laid plans end in catastrophe when the protocol is hacked, rugged or abandoned by whimsical developers.

2022 is hardly halfway complete and the year has already seen a particularly bad stretch of good intentions gone awry, which have collectively helped plunge the market into bear-market territory. Here’s a closer look at each of these instances to help provide insight into how similar outcomes can be avoided in the future.

Some developers are anonymous for a reason

Satoshi may have successfully remained anonymous while launching Bitcoin, but in most instances since then, having anonymous developers has turned out to be a red flag.

Many anonymous developers cite personal safety reasons for taking this route. While this is a valid reason in some cases, sometimes anon developers are hiding from previous misdoings or pre-planning to cover their tracks in the case of future offenses.

A flagrant example of this was Squid Game (SQUID), a Netflix-show-inspired memecoin that rallied 45,000% within a few days after launch, only for traders to realize that they were unable to sell the tokens on any exchange.

Investors eventually discovered that all the developers were anonymous and all social media channels were blocked from comments.

The crypto community has grown to be rather distrustful of anonymous developers and this can be seen in the negative reaction to the revelation that the founder of the Azuki nonfungible token (NFT) project was involved with three other NFT projects that were ultimately abandoned, leaving their holders with little to show except worthless jpegs.

Another instance of an anonymous developer going rogue occurred in 2022 when it was revealed that the anonymous Wonderland (TIME) treasury manager @0xSifu turned out to be an alleged financial criminal, along with QuadrigaCX co-founder Michael Patryn.

The revelation of this connection resulted in the collapse of several popular projects including Wonderland and Popsicle Finance, while a significant amount of criticism was directed at Abracadabra.Money creator Daniele Sestagalli.

Prior to the @0xSifu revelation, all three protocols were seeing increased adoption, but , each protocol is a mere shadow of its former success.

Having anonymous developers removes accountability from the equation and is increasingly becoming a red flag when dealing with multi-million dollar cryptocurrency protocols.

Beware of cult personalities

Finance is no stranger to cult personalities and crypto is not immune to this phenomenon.

Long-time crypto pundits will recall Roger Ver being called “Bitcoin Jesus” and hileading the charge to fork Bitcoin Core and create Bitcoin Cash (BCH). Billionaire Dan Larimer also comes to mind, and investors will recall his helping EOS (EOS) raise $4 billion during the initial coin offering (ICO) boom of 2017 to 2018. In each instance, it was a fervent flock of followers that propelled each project forward.

Neither BCH nor EOS managed to reclaim their all-time highs during the 2021 bull market despite all the hype about their future when first launched. This is possibly because a portion of the hype is centered around the personalities behind the projects.

A more recent example includes the collapse of Fantom ecosystem token prices after decentralized finance (DeFi) developer Andre Cronje deactivated his Twitter account and informed the community that he was leaving the crypto space entirely.

Cronje had become so popular that many people would buy a token just because he was involved, and when he left, many of these investors dumped their holdings, which negatively affected the tokens' prices.

While Cronje was doing what he thought was right and had no ill intentions toward the community, his actions appear to have negatively affected the crypto market due to his popularity within the community and the dedication of his followers.

The main takeaway is to be vigilant when a developer is seen as incapable of doing wrong and remember that cult-like followings can have outcomes that ripple beyond their community.

Decentralization requires involving the community

Another red flag to be on the lookout for ar decentralized autonomous organizations (DAOs) and DeFi protocols that operate in a manner that appears to be more centralized than their name would suggest.

It’s common for many protocols to claim that they are decentralized, yet they rely on centralized service providers like Amazon Web Service to ensure that they function properly.

Another pertinent example is when a project that claims to offer token holders governance rights makes a major protocol decision without consulting the community for feedback and approval.

The move by Terra (LUNA) to add BTC to its treasury as collateral for the TerraUSD (UST) stablecoin made headlines and was lauded by many, but the move was never put to a vote within the Terra community to see what token holders thought.

While there is a good chance that the plan would have been approved and the collapse of Terra still would have occurred, the blame might have fallen more on the community and less on Do Kwon, the project’s leader. It’s also worth mentioning that Do Kown had developed quite the cult following and was frequently insulting a variety of people on Twitter.

One of the main tenets of the cryptocurrency sector is adherence to decentralization and failure to do so often leads to a compromised network and dissatisfied investors.

Yearn Finance advocates for the adoption of ERC-4626 tokenized vault standard

The widely-popular DeFi protocol announced its support for the newly-passed ERC on Wednesday, stating that Yearn V3 plus ERC-4626 equals "Inevitable.”

Following the successful deployment of twenty-five previous Ethereum Request for Comments (ERC) standards, including the industry-recognized ERC-20 designed for tokens, ERC-721 for nonfungible tokens (NFTs), and the single smart contract multi-token ERC-1155; the newly-passed ERC-4626 is gaining traction within the Ethereum community for its purported yield-bearing benefits.

Referred to as the “tokenized vault standard,” ERC-4626 is set to be implemented at the next Ethereum fork upgrade following approval by the developers within Ethereum’s governance procedure.

Serving as an addition to ERC-20 — and considering the utilization of under-review EIP-2612 for the approval shares user experience (UX) — the ERC-4626 standard is expected to enact wide-scale benefits across Ethereum’s decentralized finance (DeFi) ecosystem, enhancing the composability and accessibility of yield-bearing vaults across multiple networks.

As an application programming interface (API), much of the implementation will occur behind the scenes within the network's operation, and therefore will not be particularly visible on the user-end dashboard, but will be immensely valuable for their participating experience.

One of the primary attractions to interacting with DeFi protocols for the retail market is their positively disproportionate yield generation in comparison to traditional banking bond accounts and savings offerings.

Yield-bearing assets such as SushiSwap’s xSushi, Aave’s aToken, or Yearn Finance’s yToken, enable users to stake the network's native tokens for a wrapped version, benefiting from both the acquired liquidity and interest earned.

However, as Yearn Finance succinctly points out, “to build a single app on top of DeFi's yield-bearing tokens, you have to write dozens of complex, error-prone adapters that can handle each unique variation", as well as that if you “build an app on top of one ERC-4626 vault... it will work for all other ERC-4626 tokens.”

The concept for ERC-4626 was initially pitched on Dec. 22 as an Ethereum Improvement Proposal (EIP) by five authors led by the founder of Fei Protocol, Joey Santoro.

According to an anecdotal story from co-author t11s, the 4626 number was birthed during an exercise workout, noting that the melodic rhyming pattern sounded more appropriate for the title of their invention than the more monotonous 4700 for instance.

Fundamentally viewed as a protocol standard designed to optimize and unify the technical parameters of yield-bearing vaults, the proposition swiftly sparked discussions, suggestions and rebuttals on open-source development platforms Github, Ethereum Magicians and crypto native social media Twitter, with a largely positive consensus noted throughout the community.

One responder named albertocuestacanada highlighted a concern with the potential impact of language regarding the calculateShares required to equal sharesAmount section, arguing that this would prevent vaults from implementing deposit or withdrawing fees. Santoro soon revised this section “in favor of a better invariant related to it returning the same value as a mint/deposit call in the same transaction.”
