Audit Reports

This page covers the audits that apply to Tydro: the audits of the Aave V3 base codebase, and any audits of other dependencies.

Two layers of review

Tydro's security review has two parts. The lending base is the Aave V3 codebase, which has been independently audited across multiple rounds by six firms and formally verified by Certora. Tydro then adds its own contracts and configuration on top, and those are reviewed separately. A deployment's own code and modifications are not covered by audits of the base.

Note: how to read an audit report

An audit is one input to security. A report reflects a defined scope and a point in time. It does not cover code changed after the review, and a clean report does not prove the absence of bugs. Read these reports and evaluate the level of the diligence applied, alongside the controls described in Smart contract security architecture.

Bug bounties
