Bridge rate-limiter / chain-pause as positive mitigant

Evidence summary #

GateSeal mechanism provides a protocol-level pause (not a per-window rate-limiter). No explicit per-window outflow rate-limiter confirmed on canonical wstETH bridge contracts (Wormhole+Axelar on L2s). Partial credit for GateSeal pause as a positive mitigant for core protocol operations.

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.
