Verify a domain

Publish one DNS record, run the check, and keep the proof. This guide uses the ownership-dns-txt check.

Add a TXT record

At your DNS host, create a TXT record named _neus on the domain. The check reads _neus.<your-domain>.

wallet=<your-account-address>

Use the same account address Proofable uses for the check. Write Ethereum addresses in lowercase. Only the wallet= prefix is read.

Run the check

const proof = await client.verify({
  verifier: 'ownership-dns-txt',
  data: { domain: 'example.com' },
  walletAddress: '0x...',
});

A signed request fills in the account address. Add walletAddress inside data only when it must be explicit, and it must match the signer.

Check it later

curl "https://api.proofable.me/api/v1/proofs/check?verifierIds=ownership-dns-txt&address=0x..."

DNS changes can take minutes to propagate, and longer with some providers. Record formats for other networks, and every field, are in ownership-dns-txt.
