Domain Verification

​

Steps

1. TXT at _neus.<yourdomain> (DNS host/name is often _neus when the zone is your apex or subdomain).
   wallet=<your-wallet-or-account-address>
   
   Example for Ethereum (use lowercase hex so it matches what NEUS expects):
   wallet=0x...
   
   The verifier reads wallet= only (not neus= or other prefixes).
2. Proof — include at least domain in data. You may omit data.walletAddress when the same request carries a verified top-level walletAddress (typical signed proof); the service fills in that signer address before the DNS check. The TXT line must use the same wallet or account address NEUS uses for the proof.
   const proof = await client.verify({
     verifier: 'ownership-dns-txt',
     data: { domain: 'example.com', walletAddress: '0x...' },
     walletAddress: '0x...',
   });
   
3. Check
