## Smart-account signatures

`createEVMVerifier({ call, getCode })` verifies deployed smart accounts through
ERC-1271 and counterfactual accounts through ERC-6492. The supplied `call`
must pass through an optional `to`: ERC-1271 calls include the account address,
while address-free ERC-6492 verification intentionally sends a contract-creation
`eth_call` with only `data`. Standard JSON-RPC nodes support both forms.
