Koi Finance is a next-generation decentralized finance (DeFi) platform built on zkSync, which leverages zkRollup technology to offer fast, low-cost transactions. The platform features an automated market maker (AMM) exchange, farming, and a bond platform, all designed to provide users with a comprehensive DeFi experience. One of its standout features is the ability to pay gas fees with any token, not just ETH, which keeps transaction costs between $0.01 and $0.05.

The KOI token is central to Koi Finance's ecosystem, used for governance through a vote-escrow DAO mechanism. Users can lock up their KOI tokens to gain voting rights, enhanced farming annual percentage yields (APYs), and revenue sharing. The platform supports dynamic liquidity pools, accommodating both stable and normal AMM curves, and provides fixed APY farming pools with guaranteed reward payouts​ .

Koi Finance aims to deliver a user-centric, community-driven DeFi solution, emphasizing security and efficiency. It is accessible on both Ethereum and zkSync blockchains, with a maximum supply of 1 billion KOI tokens.
