# A7A5 (A7A5) Quantum Readiness Report

> A7A5 has a QRI score of 1/100 and is assessed at Stage 0 (Unassessed / No Evidence) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Token (ERC-20 on Ethereum at 0x6fA0BE17e4beA2fCfA22ef89BF8ac9aab0AB0fc9; TRC-20 on TRON at TLeVfrdym8RoJreJ23dAGyfJDygRtiWKBZ). Standard smart-contract token with no custom cryptographic or cross-chain dependency layer..

A7A5 is a Russian ruble-backed stablecoin deployed as a standard ERC-20 token on Ethereum and TRC-20 token on TRON. Under QRI Section 7.2 (Token Inheritance), A7A5 inherits the base-layer quantum-readiness scores of Ethereum and TRON — both of which remain entirely ECDSA/BLS-dependent in production as of June 2026 and have no live post-quantum protection. The project has published zero quantum-specific work: no cryptographic inventory, no threat model, no risk assessment, no PQC migration plan, and no quantum-aware governance. The token's admin functions (mint, burn, pause, blacklist, destroyBlackFunds, fee updates) are controlled by ECDSA-based multisigs (3-of-5 and 5-of-5) on both chains — a quantum compromise of any quorum threshold would enable unlimited supply manipulation and user fund freezes. Approximately $500M in market cap and $110B+ in cumulative transaction volume are exposed with no migration, freeze, or recovery path. The QRI Score is 1 out of 100, reflecting negligible quantum readiness and complete absence of project-level quantum awareness. The project is at Stage 0 (Unassessed / No Evidence).
