Yei Finance is a multichain decentralized finance protocol focused on making it easier to lend, trade, and bridge assets across blockchain networks. Described as a decentralized, non-custodial money market protocol on Sei, it provides tools for users to put digital assets to work while retaining control of their funds.

Its YeiLend product lets users supply supported assets and access borrowing markets, with listed tokens including USDC, SEI, USDT0, Wrapped Ether, Wrapped Bitcoin, and SolvBTC. YeiSwap enables token swaps across Sei and supports liquidity provision. The platform says liquidity providers can earn swap fees, lending interest, and additional YeiSwap rewards, while using YeiLend collateral to pursue combined earning opportunities.

Yei Finance also offers access to instant liquidity through borrowing, fast, low-cost swaps, and automated vault strategies designed to optimize yields. Users can explore the application and documentation through the site. By bringing lending, trading, liquidity provision, and yield strategies together, Yei Finance aims to provide a connected DeFi experience across chains.
