# Domain

> Confirm domain control with a DNS TXT record on the account you control.

**Check ID:** `ownership-dns-txt`

## Use cases

* verified website on your profile
* team workspace and branded handles
* public trust pages for domains

## Flow Type

Lookup. NEUS resolves DNS TXT at `_neus.<domain>` and compares it to the **account address** used for this verification (see below).

## DNS record (what builders publish)

Create a **TXT** record:

* **Name / host:** `_neus` (effective lookup: `_neus.<your-domain>`, e.g. `_neus.example.com` if the apex is `example.com`).
* **Value:** a single line starting with `wallet=` followed by the **same wallet or account address** NEUS uses when it runs this check.

Supported shapes today:

| Format                              | When it matches                                                                                                                                             |
| ----------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `wallet=<address>`                  | Default. `<address>` must match the wallet or account address NEUS uses for this proof. For **Ethereum**, use **lowercase** `0x` plus 40 hex digits in DNS. |
| `wallet=eip155:<chainId>:<address>` | Only if the verification run supplies a numeric **`chainId`** in verifier options so this form is generated for the check.                                  |

Other prefixes (for example `neus=`) are **not** read by this verifier—use **`wallet=`** only.

**Other networks:** Use the address format for that network (for example Ethereum, Solana, or NEAR). For **Solana**, the string is **case-sensitive**—copy the value exactly as NEUS shows it for the proof; do not retype it with different capitalization.

| `domain`        | **Required**           | Hostname to verify (apex or eTLD+1 style you control in DNS).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                |
| `walletAddress` | **Optional** in `data` | **Still needed for a passing check:** the TXT line must match the **wallet or account address NEUS uses for this proof**. You may **omit** `walletAddress` inside `data` when the proof request already includes a verified **`walletAddress` at the request level** (signed flow); the service fills in the signer wallet before the DNS check. If you omit it **and** the request has no signer wallet, verification fails. If you **set** `walletAddress` in `data`, it must match the wallet that signs the proof (or follow your product’s allowed delegation rules)—do not use someone else’s address. |

## Example

Minimal `data` when the proof request carries the signer wallet (typical browser / server signing):

```json theme={"dark"}
{
  "domain": "example.com"
}
```

Explicit `data` (custom clients, tests, or when you want the payload self-describing):

```json theme={"dark"}
{
  "domain": "example.com",
  "walletAddress": "0x..."
}
```
