Sei Labs Proposes SIP-5 for Gradual Quantum-Resistant Account Security Upgrade

Sei introduces SIP-5 to enable optional quantum-resistant key upgrades without changing addresses, aiming to mitigate future cryptographic risks while preserving UX.

Woofun AI reports that Sei Labs has introduced SIP-5, a proposal enabling Sei Network accounts to transition to quantum-resistant security without altering addresses or forcing asset migrations. The plan allows users to attach new keys while retaining balances, transaction history, and smart contract interactions, minimizing ecosystem disruption.

The proposal advocates a gradual migration strategy, letting users upgrade at their own pace before a potential future cutoff for outbound transactions. Sei Labs notes that current post-quantum signatures are larger, potentially reducing throughput, and is exploring efficiency improvements. The framework remains open for governance discussion by validators and developers.
