Bridge rate-limiter / chain-pause as positive mitigant
Circle USYC'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 #
Teller source includes setLimits() which may implement per-window deposit/withdrawal rate limits. BSC chain has theoretical validator-set emergency-pause capability. No publicly documented protocol-level rate-limiter found. Partial positive mitigant noted but cannot confirm protocol-level implementation without public source or docs.

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.
