Does this skill support gas optimization?

Yes, it includes implementation patterns for ERC721A, which significantly reduces gas costs for batch minting operations compared to standard ERC-721 implementations.

How does it handle NFT metadata?

It supports both off-chain storage via IPFS/CID pinning and fully on-chain SVG/JSON generation via Base64 encoding for permanent data persistence.

Can I create non-transferable tokens?

Yes, the skill provides templates for 'Soulbound Tokens' (SBTs) by restricting the transfer functions within the smart contract, ideal for credentials and badges.

Is it compatible with OpenSea and other marketplaces?

Absolutely. The skill follows standard EIPs and metadata schemas recognized by major marketplaces like OpenSea, Blur, and LooksRare to ensure assets display correctly.

Implements and manages NFT standards including ERC-721 and ERC-1155 for digital assets, marketplaces, and on-chain collectibles.

The NFT Standards skill equips Claude with the expertise to design, implement, and optimize Non-Fungible Tokens using Ethereum-based standards. It provides comprehensive patterns for ERC-721 and ERC-1155 smart contracts, including advanced features like royalty enforcement (EIP-2981), soulbound tokens, and gas-optimized batch minting with ERC721A. Whether building art collections, gaming items, or dynamic on-chain metadata systems, this skill ensures best practices for security, marketplace compatibility (OpenSea, Blur), and efficient off-chain data management via IPFS.
