# Account Signature

`account-signature.<profile>.v1` verifies that an account approves its connection
to an ENS name. The ENS authority and the recorded account both approve the
same [common claim](/docs/components/common-claim).

The profile defines the supported accounts and their signing rules. Replace
`<profile>` with an exact profile identifier in the descriptor.

| Profile                                          | Accounts                      | Approval                                         |
| ------------------------------------------------ | ----------------------------- | ------------------------------------------------ |
| [eip155](/docs/methods/account-signature/eip155) | Supported EVM address records | EIP-712 signatures or ERC-1271 contract approval |

The descriptor requires `u`, pointing to the complete proof envelope. The
location stores the proof; account approval comes from the signature checks.
Successful verification returns `control` for the exact recorded account.

See the [implementer overview](/implementers/methods/account-signature) for the
shared requirements. Other profiles are not defined yet.
