What is Multi-Owner Plugin?

Multi-Owner Plugin is an ERC-6900 modular plugin that lets your smart accounts have one or more ECDSA or SCA owners. This lets your account integrate with multiple signers at once, and supports recovering your account if one signer is lost. The Multi-Owner Plugin is able to update (e.g. add or remove) owners for an MSCA, check if an address is an owner address of an MSCA, show all owners of an MSCA, and validate signed signatures of ERC-4337 enabled user operations as well as regular transactions. All Modular Accounts have the Multi-owner plugin pre-installed upon creation.
