The useName hook is used to get name from an onchain identity provider for a given address. It is implemented with useQuery from @tanstack/react-query, and returns a UseQueryResult object, allowing you to pass through all @tanstack/react-query options.

​
Usage

Get ENS name from an address: 
import { useName } from '@coinbase/onchainkit/identity';

const address = '0x02feeb0AdE57b6adEEdE5A4EEea6Cf8c21BeB6B1';
const { data: name, isLoading } = await useName({ address });
Get Basename from an address: 
import { useName } from '@coinbase/onchainkit/identity';
import { base } from 'viem/chains';

const address = '0x02feeb0AdE57b6adEEdE5A4EEea6Cf8c21BeB6B1';
const { data: name, isLoading } = await useName({ address, chain: base });

​
Returns

useQuery<Promise<GetNameReturnType>>

type GetNameReturnType = string | Basename | null;
