# Gate (GT) Quantum Readiness Report

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

Evaluation date: 2026-06-02. Review status: draft. Evaluated scope: Native GT on GateChain mainnet (including EVM module). Cross-chain GT representations on Ethereum (ERC-20) and Gate Layer are noted as dependencies but are not the primary evaluated scope..

GateChain (GT) is an EVM-compatible Layer-1 PoS blockchain operated by Gate.io. Despite 2020 marketing claims that its '40-16-byte hash string' address format provides 'post-quantum attack prevention,' the chain's production cryptography is entirely classical: Ed25519 for native account spend authorization and consensus VRF, and secp256k1/ECDSA for the EVM module. Both are vulnerable to Shor's algorithm. No PQC or hybrid-PQC algorithms exist in the public codebase (github.com/gatechain/crypto), no quantum migration roadmap has been published, and GateChain is conspicuously absent from Gate.io's own May 2026 analysis of quantum-resistant chain roadmaps. The 'post-quantum' address claim appears to reference only a longer hash-based address format, which at best delays public key exposure until first spend (identical to Bitcoin P2PKH) and provides no protection once a transaction is signed. All native GT, ERC-20 GT, and Gate Layer GT remain fully quantum-vulnerable across all attack windows with no migration, freeze, deprecation, or recovery path. The QRI Score of 1 reflects zero meaningful quantum protection, zero migration progress, and unsubstantiated public claims about quantum resistance.
