Is Fluid Safe?
Risk Grade: B- (32/100)
Fluid is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — impressive capital efficiency but five novel mechanisms sharing one pool is an experiment at unprecedented scale
A lending protocol where your collateral and debt simultaneously earn trading fees from a built-in exchange. It rocketed to $6B in deposits by letting the same capital work across lending, vaults, and trading. Its C+ grade reflects extreme novelty risk from five untested mechanisms sharing one liquidity pool.

Key Risks for Fluid Users
All $6B sits in one shared liquidity layer. A single bug in any of the three products (lending, vaults, or the exchange) could drain everything at once
The code is heavily optimized with low-level programming that is harder for security auditors to read. Critical bugs can hide in the complexity
Growing to $6B this fast without a major stress test means the first crash will reveal whether these novel mechanisms actually work under pressure
Top Risk Factors
- •Extreme gas optimization using inline assembly sacrifices code readability, complicating audits and obscuring potential attack paths
- •Cross-contract reentrancy possible due to check-effect-interaction pattern violations in Vault functions
- •Rapid TVL growth (peaked at $6B, currently ~$1B) at unprecedented speed increases systemic importance without proportional battle-testing
