# United Stables (U) Quantum Readiness Report

> United Stables has a QRI score of 0/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-06. Review status: draft. Evaluated scope: Standard ERC-20/BEP-20 stablecoin token on Ethereum and BNB Chain, including token-specific admin/mint key controls and EIP-3009 signature-based transfer path. Host-chain consensus, P2P, and base-layer security inherited per QRI Section 7.2..

United Stables ($U) is a USD-pegged stablecoin deployed as a standard ERC-20/BEP-20 token on BNB Chain and Ethereum, backed 1:1 by fiat and stablecoin reserves. As of the evaluation date (2026-06-06), the project has performed zero identifiable quantum readiness work: no public cryptographic inventory, no quantum threat model, no PQC or hybrid-PQC implementation, no migration roadmap, and no quantum-specific governance or incident-response processes. All cryptographic operations — including standard transaction signing, EIP-3009 gasless transfers, admin/mint key authorization, and proxy upgrade authority — rely exclusively on classical ECDSA (secp256k1). The token inherits the classical quantum vulnerabilities of both host chains (BNB Chain and Ethereum). With ~$1.07B in circulating market cap and ~$1.01B fully diluted valuation, the quantum-exposed value-at-risk is material. The QRI Score of 0 reflects zero earned points across all five scoring categories, bound by a Readiness & Risk Cap of 10 (no public cryptographic inventory). The project is classified at Stage 1 (Quantum Risk Assessed) because the quantum vulnerability is readily assessable from public mainnet evidence, even though the project itself has published no quantum assessment.
