TIL CryptoPunks ownership is an internal mapping mapping (uint => address) public punkIndexToAddress; Most docs state CryptoPunks are an ERC-20 token However, the contract only implements balanceOf(). If they were a true ERC-20 token, the owner of each punk would be untrackable onchain Instead, there is this function: transferPunk(address to, uint punkIndex) This ensures the owner mapping of a punk remains consistent onchain, when transferred - pre interesting !
