NFT Standards

Master ERC-721 and ERC-1155 NFT standards, metadata best practices, and advanced NFT features.

Do not use this skill when

• The task is unrelated to nft standards
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Use this skill when

• Creating NFT collections (art, gaming, collectibles)
• Implementing marketplace functionality
• Building on-chain or off-chain metadata
• Creating soulbound tokens (non-transferable)
• Implementing royalties and revenue sharing
• Developing dynamic/evolving NFTs
