ERC-721 Non-Fungible Token Standard Library

This project provides a reusable library for implementing ERC-721 compliant non-fungible token (NFT) contracts. It is primarily designed to be used as a library within the metacontract (mc) framework, enabling developers to easily integrate NFT functionality into their projects.

Overview

The library includes:

• Core ERC-721 implementation (ERC721Base.sol)
• Storage schema for ERC-721 tokens (Schema.sol)
• Storage access utilities (Storage.sol)
• An example implementation of an NFT contract (MyNFT.sol)

Usage

To use this library in your metacontract project:

1. Install the library using Forge:

   forge install ecdysisxyz/erc721
   

2. Import the necessary contracts in your Solidity files:

   import { ERC721Base } from "ecdysisxyz/erc721/src/main/functions/ERC721Base.sol";
   import { Schema as ERC721Schema } from "ecdysisxyz/erc721/src/main/storage/Schema.sol";
   import { Storage as ERC721Storage } from "ecdysisxyz/erc721/src/main/storage/Storage.sol";

3. Extend the ERC721Base contract and implement your custom logic.

Example

See examples/MyNFT.sol for a basic implementation of an ERC-721 compliant NFT contract using this library.

Features

• Full ERC-721 standard compliance
• Safe transfer and minting functions
• Approval management
• Enumerable extension support
• Modular and extensible design
• Compatible with the metacontract (mc) framework

Development Status

This project is currently in active development and should be considered a beta release. While we strive for high-quality code, the implementation is evolving and has not yet undergone a formal audit. Users should exercise caution when integrating this library into production systems.
