 * Hook for fetching Stark profile for address.

 *
 * This hook fetches the stark name of the specified address, profile picture url,
 * social networks ids, and proof of personhood a user has set on its starknetid.
 * It defaults to the starknet.id naming and identity contracts but different contracts can be
 * targetted by specifying their contract addresses
