# USD1 (USD1) Quantum Readiness Report
> USD1 has a QRI score of 1/100 and is assessed at Stage 0 (Unassessed / No Evidence) with high evidence confidence.
Evaluation date: 2026-06-06. Review status: draft. Evaluated scope: Multi-chain fiat-backed stablecoin token (ERC-20/BEP-20/SPL equivalents), including admin/governance keys, bridge dependencies, and custody paths.
USD1 is a multi-chain fiat-backed stablecoin issued by World Liberty Financial (WLFI) and custodied by BitGo, deployed as a standard ERC-20/BEP-20/SPL token across Ethereum, BNB Chain, Solana, Tron, and other networks. It has zero quantum-resistant cryptographic protection at any layer. All on-chain spend authorization inherits classical ECDSA/EdDSA from host chains. The upgradeable proxy admin is controlled by a classical Gnosis Safe multisig. Chainlink CCIP cross-chain bridging relies on classical oracle signatures. BitGo custody uses classical MPC in production (a PQ MPC simulation was completed in May 2026 but is not in production). No public cryptographic inventory, quantum threat model, migration roadmap, or PQC implementation exists. The project earns minimal points solely from having identifiable on-chain value-at-risk. The QRI Score of 1 reflects that quantum readiness has not been assessed or implemented by the project; the custodian's PQ MPC simulation is a Stage 2 signal but does not yet protect any production assets. Users and institutions should monitor BitGo's PQ MPC development and any WLFI-published quantum risk assessment.
