EVM chains could add optional post-quantum security to accounts before Ethereum's 2029 upgrade.

Quantus CEO Christopher Smith proposes that EVM-compatible blockchains can implement optional post-quantum security for user accounts earlier than Ethereum's planned 2029 quantum-resistant upgrade. Two Ethereum Improvement Proposals, EIP-8130 and EIP-8355, would allow accounts to register and rotate quantum-resistant keys without changing addresses, protecting transaction authorization and admin keys. However, this approach does not secure validators or other complex protocol elements, and users would need to migrate funds to new quantum-secure addresses. This proposal offers a faster, though partial, path to quantum security for EVM chains while broader solutions continue to develop.
