Bridge rate-limiter / chain-pause as positive mitigant
Jito'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 #
Wormhole NTT bridge for JitoSOL (Arbitrum): NTT framework implements rate-limiting on both source and destination chains per Wormhole documentation — transfers exceeding capacity are queued. Primary TVS ($877M) is on Solana (not bridge-based). Bridge rate-limiter applies to cross-chain JitoSOL token only. Solana network has validator-level pause capability (historical precedent exists). Positive mitigant for bridge surface.

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.
