rubric v1.7.0

Cross-chain bridge unverified mint pattern

Circle USYC's assessment for RD-F-106 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

T-09 v2 deferred. Circle's proprietary Cross Chain Teller for Ethereum-BSC does not fit standard bridge-signal monitoring (validator proof, deposit/mint event pairing). A fraudulent mint on BSC without corresponding Ethereum lock would require compromising the Circle-controlled teller authority EOA rather than forging a bridge proof. Signal requires custom teller-specific monitoring extension not yet built. No cross-chain anomaly observed.
