Yei Finance is a decentralized, non-custodial money market protocol built on the Sei network. It enables users to deposit assets and earn passive income, borrow against collateral through overcollateralized loans, or access liquidity via flash loans. The protocol supports liquid restaking tokens (LRTs), liquid staking tokens (LSTs), and major cryptocurrencies, and is designed to adapt as the Sei ecosystem expands.
The team draws on experience from AAVE, Wormhole, and OKX, and the company is backed by investors with a background in building blockchain infrastructure. Yei Finance takes a deliberately practical stance - prioritising secure, efficient code and risk-management tools over broad claims about disruption.
The protocol is non-custodial: users retain control of their assets throughout. Its stated aim is to make DeFi accessible to both blockchain-native users and traditional investors, offering a range of financial tools within a single on-chain platform on Sei.
