How to manage ownership of MultiOwnerLightAccount
A MultiOwnerLightAccount
has 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 MultiOwnerLightAccount
is able to:
- Update (add or remove) owners for an account.
- Show all owners of an account.
- Validate signed signatures of ERC-4337 enabled user operations as well as regular transactions.
When you connect your MultiOwnerLightAccount
to SmartAccountClient
you can extend the client with multiOwnerLightAccountClientActions
, which exposes a set of methods available to call the MultiOwnerLightAccount
with the client connected to the account.
1. Get all current owners of a MultiOwnerLightAccount
You can use the getOwnerAddresses
method on the MultiOwnerLightAccount
object, which can be accessed from a connected client.
import { multiOwnerLightAccountClient } from "./client";
const owners = await multiOwnerLightAccountClient.account.getOwnerAddresses();
2. Add or remove owners for a MultiOwnerLightAccount
You can use the updateOwners
method on the multiOwnerLightAccountClientActions
extended smart account client to add or remove owners from the MultiOwnerLightAccount
.
import { multiOwnerLightAccountClient } from "./client";
const ownersToAdd = []; // the addresses of owners to be added
const ownersToRemove = []; // the addresses of owners to be removed
const opHash = await multiOwnerLightAccountClient.updateOwners({
ownersToAdd,
ownersToRemove,
});
const txHash =
await multiOwnerLightAccountClient.waitForUserOperationTransaction({
hash: opHash,
});
