Monad proposes wallet upgrade to allow key replacement without changing addresses amid quantum risk

Monad, an Ethereum-compatible blockchain project, proposed a wallet upgrade intended to let users replace or retire the keys that control an account without changing the wallet address, with potential support for passkeys, account recovery tools, and post-quantum security measures ^{[1] [2] [3]}.

The reports describe the proposal as addressing two security problems: permanent loss of funds when a private key is misplaced and the theoretical risk that future quantum computers could break current cryptographic protections ^{[4] [1]}.

One report also says the proposal remains an early draft and that a detailed technical specification and an implementation timeline were still pending at the time of writing ^[3].
