Multi-Owner Plugin

The Multi-owner plugin enables your smart accounts to possess one or multiple ECDSA or SCA owners. This allows you to integrate your account with several signers simultaneously and facilitates account recovery if one signer becomes unavailable. The Multi-Owner Plugin can modify (for instance, add or delete) owners for an MSCA, verify if an address belongs to an owner of an MSCA, display all owners of an MSCA, and authenticate signed signatures for user operations enabled by ERC-4337 and regular transactions. Every Modular Account comes with the Multi-owner plugin pre-installed at the time of creation.
