# Koi Finance > Trade, earn yields, and participate in bonds all on one decentralized, community driven platform. Koi Finance is a DeFi protocol on zkSync Era for token swapping, liquidity provision, yield farming, and bond offerings, governed by KOI token holders. Koi Finance provides DeFi services on zkSync Era for users seeking lower transaction costs than Ethereum mainnet. Users can swap tokens with limit orders, provide liquidity in stable or standard AMM pools, earn yield through fixed-APY farming pools, and participate in bond offerings. Governance is handled through veKOI, a vote-escrow NFT that holders receive by locking KOI tokens for protocol voting rights and enhanced rewards. - Type: Protocol - Sector: Finance - Status: Active - Profile: https://thegrid.id/profiles/koi_finance ## Products - [Koi Finance](https://thegrid.id/profiles/koi_finance): Koi Finance is an AMM-based decentralized exchange and DeFi platform on zkSync Era. It supports token trading across stable, standard, and concentrated liquidity pool types with variable LP fees and limit orders. A yield farming program distributes rewards at a fixed APY, and a bond platform provides protocol-native bond offerings. A vote-escrow governance system allows KOI holders to lock tokens as NFTs (veKOI) to participate in governance, earn boosted farming yields, and receive protocol revenue shares. A paymaster service allows gas fees to be paid in supported tokens rather than ETH. (Decentralised Exchange, Live, Main Product) ## Assets - [Koi (KOI)](https://thegrid.id/profiles/koi_finance): KOI is the utility token of Koi Finance, a DeFi platform on zkSync Era. It is used for accessing farming pools, participating in protocol governance, and earning revenue sharing through the veKOI lock-up system. Locking KOI for 7 to 728 days creates a veKOI vote-escrow NFT, with voting power scaling linearly based on the locked amount and duration. (Utility) - [Vote Escrow Locked Koi (VEKOI)](https://thegrid.id/profiles/koi_finance): veKOI is a governance NFT representing locked KOI tokens on Koi Finance's zkSync Era deployment. It grants DAO voting rights, amplified farming APYs, protocol fee modification powers, and claims on the protocol treasury. Each veKOI stores the underlying KOI amount, vote share weight, and expiry date, and can be transferred, split, or merged by its holder.
