Yei Finance is a decentralized, non-custodial money market protocol built on the Sei network, designed to provide innovative and flexible financial solutions. It offers users competitive yield, empowers them to borrow through over-collateralized or flash loans, and enables them to manage risks with advanced tools-all while leveraging Sei's speed and cost. Clovis is the latest product by Yei Finance, which reached more than $400M TVL at ATH, generated $5.5M in protocol revenue over the past year, and became the largest protocol on Sei. Yei also launched the first lending-boosted DEX on Sei, where YeiSwap compounds YeiLend yields to drive $230M+ in monthly trading volume and $147M in bridge flow. Now, Clovis will expand this proven model by becoming multichain, and positioning itself as the cross-chain prime brokerage layer for DeFi.
