Follow-up reporting confirms ML-DSA-65 was added as a native account signature scheme in Devnet protocol version 139, supporting single- and multi-signature accounts, with validators able to verify transactions authorized by post-quantum keys; Testnet and Mainnet still do not accept such signatures, and Mainnet timing depends on independent audits and Testnet feedback.
State after update: Sui Devnet has added ML-DSA-65 as a native account signature scheme (reported as protocol version 139) and processed its first native post-quantum transaction; Testnet is targeted for end-2026 and Mainnet for Q1 2027, subject to independent audits and Testnet feedback.
