Sui Devnet has processed its first native quantum-safe transaction after Mysten Labs added ML-DSA-65 post-quantum signature support in release v1.82.0. The implementation lets signed transactions be submitted through the ExecuteTransaction API and verified through VerifySignature.
Why it matters
ML-DSA-65 also works with Sui multisignature transactions, GraphQL and the Rust SDK. That broadens the feature beyond a standalone cryptographic test and gives developers tools to experiment with quantum-resistant transaction flows on Devnet.
Sui's roadmap targets native ML-DSA-65 accounts on Testnet by the end of 2026, followed by native account authentication on Mainnet in Q1 2027. Both milestones remain subject to security audits and testing results.
Market impact
The update strengthens Sui's infrastructure narrative around long-term account security, but it does not yet change Mainnet authentication. The near-term signal is developer readiness on Devnet and a defined path toward broader deployment.
The key milestones to watch are the Testnet release, audit outcomes and whether the Mainnet target stays on schedule. Until then, ML-DSA-65 support remains an important development-stage capability rather than a completed network-wide migration.
