Bridge rate-limiter / chain-pause as positive mitigant

Evidence summary #

Aave's emergency mechanism is per-reserve freeze by the Granular Guardian (not an automated outflow rate-limiter). April 2026 rsETH incident demonstrated 75-minute Guardian freeze response across 11 deployments — fast human-coordinated circuit-breaker. No automated per-window rate-limiter. F185 is primarily bridge-specific; for lending protocols the analog is the emergency pause mechanism. Partial credit for the fast Guardian response but no automated rate-limiter exists.

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.
