The proposed ERC-1000 is fully compatible with both ERC-20 and ERC-721. All extensions based on ERC-20 and ERC-721 can be applied to ERC-1000. The unique functionalities of ERC-1000 can also be extended through the inheritances of ERC-20 and ERC-721 extensions. Furthermore, to facilitate the processing of on-chain data based on ERC-1000, on-chain events can be scanned or monitored and selected data can be saved off-chain as follows:
