The reference implementation of the ERC-721 non-fungible token (NFT) standard written in Solidity for Ethereum, Wanchain, and other EVM-compatible blockchains. It provides audited base, metadata, and enumerable token contracts as a starting point for developers building NFTs.

Use cases

  • deploy an ERC-721 NFT contract on Ethereum
  • create non-fungible tokens with metadata and symbol support
  • implement enumerable NFT collections with total supply queries
  • avoid re-implementing the ERC-721 standard from scratch
  • launch NFTs on BSC, Avalanche, or other EVM chains
  • learn how the ERC-721 token standard works

When to choose

  • you want an audited, battle-tested ERC-721 reference implementation
  • you need a minimal, standards-compliant NFT contract base to extend
  • you target Ethereum, Wanchain, or other EVM-compatible chains
  • you prefer a simple implementation over a full framework

When to avoid

  • you need payable function support out of the box
  • you want a feature-rich token framework with advanced capabilities
  • you need ERC-1155 multi-token or fungible token standards
  • you require actively maintained code with recent updates
