Sui Adds Post-Quantum Signatures for Quantum-Safe Accounts
PBX Science reported that the Sui Foundation "announced on August 6" plans to add two NIST-standard post-quantum signature schemes to Sui: ML-DSA-65 for everyday accounts and SLH-DSA-SHA2-128s for high-value vaults, with a testnet by the end of 2026 and a mainnet target in Q1 2027 (PBX Science).
As of 2026-08-07, there is no matching announcement on the Sui Foundationโs press center, blog, or press listings (Sui press center).
If formalized, the reported plan would put Sui on a multi-year path to quantum-safe accounts and a two-tier signature model.
