FAQ
Common questions
What is Koi Finance?
Koi is a DeFi platform built natively on zkSync — focused on trading, yield, and fixed-income style products in a zero-knowledge L2 environment.
What can I do on Koi?
In the Koi app you can:
- Swap and trade tokens
- Provide liquidity and earn yield through pools and farming
- Use bond-style products
- Participate in veDAO governance with KOI
Why zkSync?
zkSync is an Ethereum Layer 2 that uses zero-knowledge proofs for scalable, lower-cost settlement while inheriting Ethereum security assumptions. Koi was built as a native zkSync protocol rather than a bolted-on deployment.
Is Koi audited / safe?
Smart contract audits for the protocol are published in the Koi docs audits section, including reports from Code4rena, Certora, and PeckShield.
DeFi involves smart-contract and market risk; users should do their own research before interacting with the protocol.
Who founded Koi?
Koi was founded by Matt Tawil, who served as Founder & CTO focused on smart contract design, onchain UX, and security.
