# Flare (FLR) Quantum Readiness Report

> Flare has a QRI score of 7.5/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Native asset (FLR), base layer, consensus, interoperability (FTSO, State Connector, FAssets).

Flare is an EVM-compatible PoS L1 network using Avalanche's Snowman++ consensus. The production network relies entirely on classical cryptography (secp256k1 ECDSA for accounts/transactions and likely BLS for validators). While Flare Research published a 2022 whitepaper proposing a hybrid ECDSA + CRYSTALS-Dilithium signature scheme for the EVM, this remains a theoretical design with no evidence of testnet or mainnet implementation. All quantum-critical layers, including spend authorization, consensus authentication, and cross-chain interoperability protocols (FTSO, State Connector, FAssets), remain vulnerable to quantum attacks. The project qualifies for Stage 2 due to the existence of a public mitigation design, but scores low due to the complete absence of production protection or migration tooling.
