# Starknet (STRK) Quantum Readiness Report

> Starknet has a QRI score of 35/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-06-01. Review status: draft. Evaluated scope: Native asset (STRK), L2 protocol, StarkGate bridge, and Ethereum L1 settlement dependency.

Starknet scores 35/100 (Stage 2 — Mitigation / Development). The network benefits from quantum-resistant STARK proofs for state-transition integrity, and native Account Abstraction provides a technically viable path for users to adopt PQC signatures (Falcon-512 demonstrated on mainnet). However, as of June 2026, production spend authorization defaults to Stark curve ECDSA, consensus authentication uses Ed25519 via Malachite BFT, the StarkGate bridge permits unrestricted two-way flow to quantum-vulnerable Ethereum L1, data availability depends on quantum-vulnerable KZG commitments (EIP-4844), and the state commitment scheme still relies on ECC-based Pedersen hashing in contract tries. Essentially zero economic value is protected by PQC today. The project has published a credible quantum risk assessment (StarkWare, December 2024) and lists quantum-resistant cryptography on its Phase 4 roadmap, but production protection is not yet material.
