Venus Liquidator
Summary
The Venus Protocol is a decentralized, algorithmic-based lending and credit system on the Binance Smart Chain. It enables users to utilize their cryptocurrencies by supplying collateral to the protocol that may be borrowed by pledging over-collateralized cryptocurrencies. The Venus protocol operates on a granular architecture, where the Liquidator smart contract acts as an interface to initiate the liquidation process of borrowed positions. The core mechanisms of lending/borrowing such as health factor checks, evaluation of borrow positions, and more are implemented within the Comptroller contract, which is out-of-scope for this security audit and may have its own vulnerabilities. The security audit revealed several low- and info-severity issues related to input validation and protocol-specific business logic. Overall, the code of the Liquidator contract is well written following best industry coding practices. We recommend fixing the identified security issues and improving the test suite to increase the code coverage and the SuMo score. **Fix Review Update** The majority of the issues were acknowledged by the Venus team since they want to address them in a future update.
