Full-Stack Engineer
About the Project
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. Yei Finance also had a successful TGE, launching at $200M FDV and currently sits at around $350M, rewarding hundreds of thousands of users and community members in the process. Now, Clovis will expand this proven model by becoming multichain, and positioning itself as the cross chain prime brokerage layer for DeFi.
