Venus - Correlated Oracles

Off-Chain (Public)

Audited on 2024/06/27

No active critical issues

Summary

This audit covered an oracle system used in the wider Venus ecosystem. This oracle system is designed to work with correlated tokens and return the USD price of the underlying token amount for one correlated token via a mix of native token contracts and staking managers. The audit has not revealed any significant issues, only a few Low- and informational-severity Issues that should still be addressed before contracts are deployed. The audit report also contains the VER-COR-2 issue that the Venus team reported to us. Overall, the code is well-written and documented. The test suite consists of 128 tests with 92.16% coverage. **Fix Review** All issues have either been fixed or acknowledged.
