Bridge rate-limiter / chain-pause as positive mitigant
dYdX v4 (dYdX Chain)'s assessment for RD-F-185 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
dYdX Chain has demonstrated chain-pause capability: October 2025 chain halted automatically via consensus failsafe when a liquidation error was detected, preventing further fund movement until the validator set coordinated a patched binary. This effectively served as an outflow rate-limiter in practice. No formal per-window USD outflow rate-limiter exists (EVM-style). The insurance fund covers residual losses via governance vote. Yellow: demonstrated chain-pause capability (positive mitigant); no formal per-window rate-limiter.

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.
