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.

Methodology #
Detect cross-chain activity consistent with an unverified mint on the destination chain (deposit on source without corresponding verified proof on dest).
