Sui Adopts Post-Quantum Signature Schemes In Move Toward Quantum ReadinessGrand Cayman, Cayman Islands, August 6th, 2026, ChainwireSui is adding two NIST-approved post-quantum signature schemes, so accounts can move to quantum-safe keys derived from the recovery phrase users already hold. Sui, where money moves as freely as messages, announced today that it is adopting two post-quantum signature schemes in its move toward quantum readiness. That’s why Sui is adopting two signature schemes matched to different kinds of risk, rather than betting on one algorithm. Post-quantum accounts arrive as an additive, opt-in capability, through the same rollout path zkLogin and passkeys used.
