Hey @omgcorn
Happy to see the great Yearn on Optimsim
Very clear everything, just one question, maybe a small request.
Can you define the introduction of veYfi, and how it will be what you comment? Could Yearn commit to this idea and attach it to your proposal?
Thank you Jadmat. We are happy to be here.
I think I know why you are asking that question! The answer is we are not going to be distributing $OP to veYFI holders. Just like in our proposal, we are going to distribute 100% of the $OP to yVault users.
If you donāt mind I want to avoid any potential confusion and not comment on veYFI in this context/thread.
I reviewed the proposal and personally donāt have any issue with it (canāt speak for DeFi Committee A) and think this proposal will help grow the Optimism ecosystem so Iām supportive.
Yearn needs almost a full year to get partners to build on it? Iād imagine at least a few would sign up more quickly. I mean, just off the top of my head, Resonate could get you set up in a day, probably @RobAnon? And then within 20 weeks we could collectively reassess needs.
A million OP for almost a year of runway strikes me as excessive, as much as I very much would like Yearn to come onboard ASAP.
And if your target is partners, why not earmark the funds specifically for partner or joint programs/pools rather than overall liq mining? That strikes me as having more follow-on benefits and allows you to sidestep the question of incentivizing too much mercenary capital.
Weāre definitely working with @RobAnon at Revest already and heās aware of these vaults. Iāve included them in my list of partners who already committed to building on top of our vaults on Optimism: Alchemix, QiDao, Swype, Rhino, Omni, Spool, Revest, Abra, DeFi Saver, Tapioca. There will be many more.
Iām trying to be realistic about development cycles. It takes time for things to be built. Weāve been working with @RobAnon on the ERC 4626 adapter heās building for a few weeks now already and thatās just one part of what theyāre building.
You bring up a good point about earmarking for specific protocols. I think the length and partners here will naturally be less mercenary. If we donāt earmark for specific protocols I think it could be a catalyst for development to get onboard the Optimism train. The levers we do have are to incentivize vaults that partners are using the most.
Can confirm, weāre excited to build on the vaults yall have put together. Our ERC-4626 systems should be easy to get onboarded with your systems 
And thanks for the shoutout to the both of you!
Voting recommendation: Yes
Rationale: Yearn is a well established project with high TVL. We support this proposal and believe it will drive ecosystem growth and is a good use of funds.
The defi shadow committee ā which is not an official committee ā recommends voting against this proposal. There are some limited but high-level changes weād liked to have seen, but we affirm that in principle we want to do as much as is reasonable to support Yearnās onboarding onto Optimism.
We view Yearn as a key DeFi building block that Optimism would greatly benefit from. However, 1M OP over 40 weeks seems excessive, and we believe reducing the duration and size of this proposal to 500k OP over 20 weeks is more appropriate. This should be sufficient time for Yearn to show some positive traction and integrations, and the opportunity would be there to present a second proposal for another wave of incentives.
Yearn has a stellar reputation in the Ethereum community as one of the original DeFi projects. Optimism stands to gain tremendously by helping Yearn grow a foothold hereānot just from the TVL their vaults will bring but from the integrations that Yearn enables with other protocols. Other projects are likely to follow Yearn here to build on top of them. There is a great multiplier effect reaped from their mere involvement, which is not something we can say for every project.
I am an Optimism delegate [Delegate Commitments - #18 by katie] with sufficient voting power and I believe this proposal is ready to move to a vote.
Voted yes - Following my own committee recommendation 
Voted Yes in accordance with committee recommendation.
Short duration of 6 month would have been much better but their explanation with reference to Arbitrum support a longer duration.
Yearn would be a great addition to OP but without an OP vault and with the reward rate being so high at 25,000 / week, I think the grant size should be significantly smaller. I am voting no and would like to see a revised proposal.
Voted yes for this proposal
I do agree with the commiteeās recommendation and believe yearn is a good match for this grant.
But I will abstain from this vote since I am a yearn multisign signer and though I get no benefit or get in any way compensated for this role, it could be seen as a potential conflict of interest which I would like to avoid.
[Final]
Voting: Yes
Following the DeFi A committee recommendation,our members considered this proposal as valuable for the DeFi ecosystem and Yearnās good reputation. Weāre aware of OPās high amount requested but in general terms this proposal seems reasonable. Please set up a L2 recipient address as soon as possible for everyone to see where funds are going for.
@omgcorn can you provide a Telegram handle or other contact method so the Optimism team can get in touch about paying out this grant! Feel free to DM or email palash@optimism.io
