Is Compound V3 Safe?
Risk Grade: B- (31/100)
Compound V3 is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — battle-tested since 2018 but proven vulnerable to governance attacks and has the largest DeFi accounting bug on record
One of DeFi's oldest lending protocols where you deposit crypto to earn interest or borrow against your holdings. It manages $1.3B in deposits and has raised $79M. Its C+ grade reflects a history of governance attacks ($24M stolen via a vote in 2024) and a past $147M accounting bug.

Key Risks for Compound V3 Users
In 2024, a group of whales coordinated a governance vote (Proposal 247) to steal $24M from the treasury. Low voter turnout makes this attack repeatable
A past bug accidentally gave away $147M in rewards. This was the largest accounting error in DeFi history and shows the code can have expensive surprises
Each lending market uses only one borrowable asset. If everyone wants to borrow at once, you can't withdraw your deposits until borrowers pay back, potentially locking your money for days
Top Risk Factors
- •2024 governance attack extracted $24M COMP from treasury via coordinated whale voting (Proposal 247)
- •Historical $147M bug in reward distribution contract — largest DeFi accounting error
- •Single base-asset architecture concentrates all borrowing risk in one asset per Comet market
