Bridge rate-limiter / chain-pause as positive mitigant

Evidence summary #

POSITIVE FINDING: V2 upgrade (June 2025) added IBC rate limiting capping BABY token exits at 10% of native supply within 24 hours — explicit outflow rate-limiter. No admin-triggered chain-level pause mechanism identified (Cosmos SDK x/crisis is validator-consensus-based halt, not admin key). Score yellow: rate-limiter present (positive) but no admin-triggered chain-pause capability separate from consensus. The rate-limiter is a material security mitigant for cross-chain outflow risk.

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.
