Bridge rate-limiter / chain-pause as positive mitigant
Frax Finance'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 #
Fraxtal L2 is an OP Stack rollup: sequencer has emergency-stop capability controllable by Frax team. FraxFerry bridge has permissioned operator-controlled pause. No per-window outflow rate-limiter documented for frxUSD LayerZero OFT adapter. Chain-pause exists for Fraxtal L2 but not for Ethereum mainnet frxUSD operations. Partial positive mitigant: bridge pause capability present but rate-limiter absent for primary OFT 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.
