DESCRIPTION
From Jan. 22, 2024 to Jan. 24, 2024, TIE Finance engaged Veridise to review the security of their WBTC Lending Strategy smart contracts. The review covered the developers new lendingStrategy contract, as well as a few minor updates throughout the rest of the repository. Compared to the previous version, which Veridise has audited previously, the new version supports a new sub-strategy leveraging Wrapped Bitcoin (WBTC) as collateral in AAVE, while using that collateral to obtain Ethereum to reinvest in other sub-strategies. The changes also contained some minor code changes and new interfaces required to support the new strategy. Veridise conducted the assessment over 6 person-days, with 2 engineers reviewing code over 3 days. The auditing strategy involved a tool-assisted analysis of the source code performed by Veridise engineers as well as extensive manual auditing.
