# ERC721General The ERC721General contract allows you to specify a specific token ID when you invoke the mint function. This is good for things like letting users select the specific artwork they’d like to mint, or for cases where you’d like to design your own logic for how token IDs get assigned to minters. This contract also allows the metadata for each token ID to be distinct. ### Contract link {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
