Bridge signer-set change proposed/executed
Circle USYC's assessment for RD-F-103 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Circle's Cross Chain Teller is a proprietary issuer-controlled mechanism, not a public validator-set bridge. There is no Guardian set, no LayerZero DVN, no Wormhole-style signer set. The Cross Chain Teller for Ethereum-BSC coordination does not have a public signer registry matchable to the SignerAdded/SignerRemoved event pattern that RD-F-103 targets. The profile confirms this is NOT LayerZero (layerzero.present: false) and NOT CCTP.
