yETH is Live
https://medium.com/media/257fb156c3dbb6fe5d24009aa26cac7e/href
yETH IS LIVE! May the memes be many, and the yETH yield be yolked.
“But what if I don’t have yETH to stake to st-yETH?”
Well, if you don’t have sfrxETH, or swETH, or wstETH, or ETHx, or cbETH to Deposit and acquire yETH on the yeth.yearn.fi site…
https://medium.com/media/ac303e23033dec2bfc9a4cb8db981827/href
…yETH is now available via @CowSwap !
Take your yETH to yeth.yearn.fi, go to Stake/Unstake, and stake your yETH to acquire st-yETH.
Remember, yETH does not earn liquid staking yield — only st-yETH does.

The APR isn’t Despicable — it’s the yield from last week. You can still be a minion-aire — just don’t forget to Vote! Voting starts this week.
https://medium.com/media/446cbe2d444ebbfde92b389e34d75d5f/href
See? Even the Lizard People are getting excited.
https://medium.com/media/ebf5a02de0b578171449bfee6ecfd0ba/href
Still on the fence? Well, maybe you should carefully get down from there. Each asset in yETH has its own asset composition safety band, and as a basket of 5 LST’s, yETH is a risk-adjusted token by design.
https://medium.com/media/7634c37304b810943de4d3d271e11932/href
No truer words have ever been spoken by William Stakespeare. Sourced from Stakespeare’s masterpiece, Sonnet 18, “Shall I compare yETH to a Summers day?” written in iambic pentameter, it is an inspirational piece that has moved liquidity in ways never seen before. As you contemplate your yield, along with the rhyme scheme, ababcdcdefefgg, we encourage you to listen to the brilliance presented by the Rich Men of North Richmond as they sing a song that truly captures our generation’s plight in DeFi.
Yearn v3 is now (kinda) live (on Polygon). And so are the v3 Docs!
https://medium.com/media/71f9e323154af30a8cde05651dccbb13/href
When the simps in the crib ma,
doc it like it’s hot,
doc it like it’s hot,
doc it like it’s hot…
When the Yanks try to “Soccer” you,
Footy like it’s hot,
Footy like it’s hot,
Footy like it’s hot,
I got the V3 on deploy and tokenized strats,
and I fund the best Leagues 4626 on stacks…
https://medium.com/media/29e78e869ed7bf9f890776a7ea277305/href
Armed with the V3 docs, unique ERC-4626 compliant tokenized strategies are yours to create. Just ask Schlag — he deployed his own ERC-4626 compliant Fantasy Football League.
Be creative like Schlag. Schlag is a dime piece — just like our V3 docs.

Yip-74 & YIP-75 Recaps

🗳️ YIP-75: Launch V3 is now livehttps://t.co/poZ9qIi9Z9
Yip-75: Launch V3 has passed! 194veYFI “For” to 38 veYFI “Against”.
V3 contracts are already deployed on multiple chains, with an initial rollout focus directed to Polygon chain. By implementing V3 in areas where V2 has a limited presence, Yearn can increase market share while also battle testing V3 code prior to starting TVL migration on Ethereum.
yearn on Twitter: “🗳️ YIP-74: Wintermute YFI Loan & CRV Plans is now live.https://t.co/sJYRbhokFI / Twitter”
🗳️ YIP-74: Wintermute YFI Loan & CRV Plans is now live.https://t.co/sJYRbhokFI
YIP-74 has been voted “Against” by a significant majority: 10 veYFI “For” to 167 veYFI “Against”.
Discourse within the gov.yearn.fi proposal forum was amicable and detailed, and included revisions with an updated proposal. Wintermute’s Ask: “Wintermute Trading is requesting approval for a 12-month loan of 350 YFI ($2.18M) at a 0.10% interest rate from the DAO’s treasury.”
In return, Wintermute would “use up to 3M CRV tokens to buy yCRV, deploy yCRV tokens to the yCRV-CRV pool and stake this on yearn.”
- Additional terms can be found in the snapshot vote, linked above.
Primary concerns were centered around Wintermute’s lack of collateralization, and overall “unbalanced” proposal terms. Although the revised proposal was raised to YIP status, the veYFI voters within the Yearn community were not receptive to Wintermute’s proposal terms. - For additional information and coverage, check out this article covered by DLNews, featuring an interview with Wintermute’s CEO.
Yearn doesn’t use upgradable Proxies
banteg on Twitter: “how yearn approaches thiswe famously don’t use upgradable proxies anywhere. when a vault is superseded by a new version, all its strategies are replaced by a router strategy which deposits to the new vault. you can migrate anytime or continue to earn yield in the old vault. https://t.co/6MzsOpNBGR / Twitter”
how yearn approaches thiswe famously don’t use upgradable proxies anywhere. when a vault is superseded by a new version, all its strategies are replaced by a router strategy which deposits to the new vault. you can migrate anytime or continue to earn yield in the old vault. https://t.co/6MzsOpNBGR
Yearn is notorious for not using upgradable proxies anywhere. This is a risk-mitigating standard utilized to benefit Yearn Vault users.
Requiring users to upgrade or risk losing their funds is not in alignment with Yearn’s core values of providing risk-mitigated yield to users via more “passive yield” strategies.
Therefore, if a new version of a vault becomes a better option, the old vault continues to earn yield, and all its strategies are routed into this new vault. This allows the users to migrate anytime or continue to earn yield in the old vault.
- As a friendly reminder, all DeFi users should always be monitoring their wallets, deposits, and funds due to new, and ever-present risks in this rapidly evolving space.
yAcademy Highlights

Support Shell, or the next generation of auditors?Hmm, tough call 🤔 https://t.co/bpKUukzJ8C
yAcademy recently participated in their first Gitcoin Grants round, GG18! For those unfamiliar, “Gitcoin Grants is a quarterly initiative empowering early-stage builders through a combination of crowdfunding and grants.”
- DeFi builders can submit applications demonstrating that they qualify for the criteria established for the respective two-week grant round. During that two-week period, anyone can drive funding and make individual donations towards the qualifying builders.
- Gitcoin Grants then uses a Quadratic Funding method and funds from their Matching Partners to “match” the funding raised, wherein the number of contributions is weighted more heavily than the amount funded.
- Funds raised are provided to the builder, so that they can continue building and positively contributing to DeFi’s growth, and for the betterment of the greater community.
- Follow @yAcademy on Twitter, so you don’t miss a future opportunity to contribute to your favorite free and open-source auditing academy. It’s a public good.

Hack the Vault: GG
yearn on Twitter: “We thank everyone who tried to hack the v3 Vault as part of the Crypto Twitter battle test 💰🫡. The $20,000 remained un-rugged and the game has now concluded.Stay dialed in for more v3 launch info in the coming weeks. https://t.co/bWyVYYltQM / Twitter”
We thank everyone who tried to hack the v3 Vault as part of the Crypto Twitter battle test 💰🫡. The $20,000 remained un-rugged and the game has now concluded.Stay dialed in for more v3 launch info in the coming weeks. https://t.co/bWyVYYltQM
The V3 Vault remains unscathed and unhacked. The vault’s contents have been removed.
If I had to guess why the Vault was left unhacked, I’d probably attribute it to the fact that the CT hackers forgot to rent matching mini-coopers for their heist.
Also, Yearn takes security seriously.
To those who participated, we thank you for playing and supporting the CT Battle Test game!

@MarcoWorms features @fubuloubu’s excellent write-up discussing the parallels between hardware engineering and building aircraft. The article explores how various concepts of aerospace engineering can be applied to building smart contracts, and provide beneficial failure mitigation during various phases of development.
In this write-up, you will learn about FMECA, FHA, and TRL scores, and how to increase the probability of hitting PMF. @Fabululoubu goes on to describe how Crypto typically utilizes “test in prod” implementation, similar to how aerospace projects go through Ground and Flight Test procedures. With @cHaOSneT, “test in prod” becomes viable via an “ephemeral testnet product” in which full-stack simulations can be run whilst limiting impact to project teams and users.

@Fubuloubu explores building a ERC4626 on-chain “yield oracle” tied to Vault implementation, discusses ERC-4626 evolution, and shares their Call to Action for ERC-4626 vaults to conform to the standard for smooth integration in the community.

Earn yield on your YFI via the YFI silo, and borrow crvUSD. Or be a crvUSD provider to the YFI silo. Personally, I went with the first option and then took my crvUSD to acquire more st-yETH. There are lots of applications and strategies you can utilize with your crvUSD — just don’t over-extend your lending position, and as in all lending protocols, monitor your Health factor — you may need your YFI sooner than you think.
