Security

VII Finance is developed with security in mind, and simplicity is the key. As a credit-based market-making protocol, VII Finance leverages Euler v2 for credit functionality and Uniswap V4 for market making.

We've kept our smart contracts minimal, implementing only what is absolutely necessary. However, in DeFi, funds are only as secure as the least secure component, so we have taken extensive measures to secure our codebase.

Audits​

VII Finance contracts have undergone two extensive audits with audit providers who have experience with both Euler v2 and Uniswap V4:

Cyfrin Audit Report

Cantina Audit Report

A public audit competition was hosted on Cantina platform and we received coverage from multiple Security Researchers

33Audits Audit Report

Independent security assessment by 33 Audits team, providing additional security validation and recommendations.

Battlechain Deployment​

VII Finance has deployed Uniswap V3 support on Battlechain testnet to improve the security of the protocol.

You can interact with the deployment via the live frontend at vii.finance/markets.
