Bridge rate-limiter / chain-pause as positive mitigant
Hyperliquid'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 #
POSITIVE MITIGANT: Bridge2 Lockers (2-of-5) can pause the entire bridge. L1 validators can execute emergency actions in ~2 minutes (JELLY demonstrated). disputePeriodSeconds creates withdrawal challenge window. October 2024 bridge outage confirmed emergency lock functioned correctly (bridge locked, funds safe, unlocked post-diagnostic). No graduated per-window outflow rate-limiter - Lockers pause entirely. Significant positive mitigant for mass-drain scenarios at ~$3.58B Arbitrum Bridge2 TVL (2026-05-07).

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.
