Bridge rate-limiter / chain-pause as positive mitigant
Liquid Collective (LsETH)'s assessment for RD-F-185 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
CoverageFund.1.sol is a simple ETH donation buffer: pullCoverageFunds() callable only by River contract, donate() accepts contributions. No automated insurance fund logic with complex invariant risk. Protocol also references Nexus Mutual slashing coverage via user agreement. No C23-class insurance fund logic bug surface identified. The CoverageFund is a minimal accounting contract, not an automated stability mechanism with complex logic.

Methodology #
Determine whether the bridge implements a per-window outflow rate-limiter (and at what cap), and whether the protocol team can trigger a chain-level or validator-set emergency pause.
