Yei Finance is a Sei-native DeFi stack that combines a money market (YeiLend) and a DEX (YeiSwap) so users can borrow/lend and LP with yTokens to stack yields. Risk tooling includes E-mode for correlated assets, Isolation Mode with per-asset debt ceilings, robust liquidation rules, and flash loans; pricing is secured via API3 with Pyth/RedStone backups, and rates adapt to utilization. The team emphasizes security (Zellic/PeckShield audits) and is expanding with Clovis, a cross-chain clearing/execution layer to unify fragmented liquidity.
