Cryptographic profile

What breaks

  • Classical signatures authorizing USDS value under Shor-class adversaries once public keys are known
  • Custodial hot wallets and exchange operational keys
  • Bridges, issuers, or operator sets outside ordinary user wallets
  • Protocol admin, oracle, or guardian keys

Mitigations

  • Inventory every key that can move USDS (self-custody, exchange, multisig, protocol roles)
  • Name the host chain and bridge path for every balance
  • Document operator/admin sets for L2s and apps
  • Track ecosystem PQC research; branding is not deployment
  • Use /assessment and claims methodology pages for program framing
