What it returns

One account-abstraction (ERC-4337) smart account on one chain: the factory that deployed it, the user operation, transaction and time of that deployment, how many user operations it has sent, and the smart-account code it runs. An ordinary wallet that delegates to smart-account code (EIP-7702) has no factory and no deployment. account is null when the address never sent a user operation on the chain.

Response fields of Who deployed an ERC-4337 smart account, and how much it is used
Field	Type	Description
`address`	string	The address asked, lowercase.
`account`	object \| null	The smart account, or `null` when the address never sent a user operation on the chain.

`account.implementations[].address`	string	The implementation contract.
`account.implementations[].name`	string \| null	Its verified contract name, e.g. `"Kernel"`; `null` when not known.
