Build with names.

Resolve a name to an address on Arc. The registry and NFT registrar come from ENS, with native USDC pricing and an Arc-specific controller.

Network & contracts

Network: Arc mainnet, chain ID 5042
Native currency: USDC, 18 decimals
Controller: 0x7D76e07fAc9ACCFEf16563Affef43c950038bB87
Registry, registrar, and resolver: Read registry(), registrar(), and resolver() from the controller.

Resolve an address

const node = namehash('alice.arc')
const target = await client.readContract({
  address: resolver,
  abi: parseAbi([
    'function addr(bytes32) view returns (address)'
  ]),
  functionName: 'addr',
  args: [node]
})

Use viem’s namehash and parseAbi. An expired name resolves to the zero address. Treat that as an unavailable destination.

Protocol scope

Names contain 3 to 63 ASCII letters, numbers, or hyphens. Registration uses commit/reveal with a 60-second minimum wait and a 24-hour commitment lifetime. The minimum registration is one year.

This is an independent Arc registry. Existing Ethereum ENS names and integrations do not automatically resolve .arc names. The adapted controller and resolver have automated tests but no independent security audit.
