Monad Proposes Key Rotation Without Changing Wallet Addresses

Monad’s “Flexible and Upgradeable Account Authentication” draft, posted on August 21 by Kushal Babel and Jan Camenisch, would allow wallet accounts to add, rotate or retire authenticators while retaining a fixed 20-byte account address.

The design remains a draft and does not yet include a detailed implementation specification.

Under the draft, an account’s address would remain fixed at 20 bytes rather than being tied permanently to one authentication setup. The associated authentication configuration could change over time, allowing an account to retain its existing address while changing the authenticators authorised to control it.
