Contributing Factors

+15CCTP is the canonical native-USDC cross-chain rail used by major aggregators/wallets (LI.FI, across, etc.) and is integrated on 13+ chains — a forged-mint or prolonged pause would disrupt native-USDC movement ecosystem-wide

+15Scored 60 (more isolated than the issuer's 30): CCTP failure does NOT directly depeg spot USDC on the canonical chain; blast radius is the cross-chain transfer layer and destination-chain USDC supply integrity, not every DeFi position holding mainnet USDC

+15Analyst judgment — circle-cctp is not yet in cross_protocol_composition.json

+15ACTION FOR REVIEWER: add circle-cctp to cross_protocol_composition.json (downstream: bridge aggregators / multi-chain USDC integrations)
