This skill provides a comprehensive toolkit for developing non-fungible tokens on Ethereum and EVM-compatible blockchains. It masters the implementation of ERC-721 for unique items and ERC-1155 for multi-token systems, covering critical aspects such as on-chain/off-chain metadata management, EIP-2981 royalty standards, and gas-efficient minting patterns like ERC721A. Whether building art collections, gaming assets, or decentralized identity systems via soulbound tokens, this skill ensures smart contracts are secure, interoperable with major marketplaces, and optimized for production environments.
