How does it handle NFT metadata?

It provides patterns for off-chain metadata hosted on IPFS as well as fully on-chain metadata where JSON and SVG images are generated directly within the smart contract.

Which NFT standards does this skill cover?

This skill covers ERC-721 (individual non-fungible tokens), ERC-1155 (multi-token standard for fungible and non-fungible assets), and ERC721A (gas-optimized batch minting).

Can I create non-transferable tokens?

Yes, the skill includes logic for Soulbound Tokens (SBTs) by overriding transfer functions to prevent assets from leaving the original owner's wallet.

Does it support marketplace royalties?

Yes, it includes implementation details for EIP-2981, the universal royalty standard supported by major marketplaces like OpenSea and LooksRare.

開発者ツール

Implements industry-standard NFT protocols including ERC-721 and ERC-1155 with advanced features like dynamic metadata and royalties.

概要

This skill provides comprehensive guidance and production-ready patterns for developing non-fungible token (NFT) ecosystems. It covers core standards like ERC-721 and ERC-1155, while providing advanced implementations for gas-optimized batch minting (ERC721A), EIP-2981 royalties, and non-transferable soulbound tokens. Whether you are building an NFT marketplace, a blockchain-based game, or a digital identity system, this skill ensures your smart contracts follow best practices for metadata handling, security, and marketplace compatibility.
