Yearn Finance helps DeFi users earn yield on digital assets by automating investment strategies across lending protocols.

Yearn Finance helps DeFi users maximize returns on digital assets through automated yield optimization. Users can deposit assets into vaults that automatically shift capital between lending protocols like Aave, Compound, and Curve to capture the best opportunities. Yearn socializes gas costs, automates rebalancing, and aims to eliminate the need for technical DeFi expertise through its passive investment strategies.

## Products

- [yVaults](https://thegrid.id/profiles/yearn_finance): yVaults automate yield generation through smart contracts that allocate user deposits across DeFi lending protocols and liquidity pools. The system implements ERC-4626 tokenized vault standards, enabling single-strategy or multi-strategy capital deployment while socializing gas costs and automating portfolio rebalancing across opportunities in protocols like Aave, Compound, and Curve. (Yield Aggregator, Live, Main Product)
- [yLockers](https://thegrid.id/profiles/yearn_finance): yLockers convert locked governance tokens into liquid, tradable derivatives based on vote escrow mechanics. The system maintains governance rights and yield benefits while enabling token liquidity through tokenized escrowed positions that users can trade without sacrificing voting power. (Liquid Staking, Live)
- [yPools](https://thegrid.id/profiles/yearn_finance): yPools provide community-governed liquidity pools for liquid staking tokens with automated market maker functionality. The system dynamically optimizes risk-adjusted yields through automated capital allocation and rebalancing mechanisms across LST positions. (Pool Software, Live)

## Assets

- [yearn.finance (YFI)](https://thegrid.id/profiles/yearn_finance): YFI is the governance token of Yearn Finance. It is used to vote on protocol decisions and treasury allocations, with holders able to lock their tokens to receive veYFI for increased voting power. The veYFI mechanism adapts Curve's vote-escrow model, requiring longer lock periods to gain more influence over governance and access to boosted yields on vault deposits. (Governance)
