Each CryptoKitty is represented by a unique ERC-271 token, which contains specific attributes and characteristics that make them distinct from other CryptoKitties.

Here is a simple code example for creating an ERC-271 token contract using the Solidity programming language:

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC271/ERC271.sol";

contract MyToken is ERC271 {
    constructor() ERC271("MyToken", "MTK") {
    }

    function mint(address to, uint256 tokenId) public {
        _safeMint(to, tokenId);
    }
}

This contract inherits from the ERC271 token standard provided by the OpenZeppelin library and creates a new token called “MyToken” with the symbol “MTK”. The mint function can be called to mint a new token with a specific ID and assign it to a given addressString of text that designates the location of a particular wallet on the blockchain.
