Is gas optimization included?

Absolutely. The skill features patterns like ERC721A which significantly reduces gas costs during batch minting operations.

Does this skill support both ERC-721 and ERC-1155?

Yes, it provides comprehensive implementation patterns and code samples for both individual non-fungible tokens (ERC-721) and multi-token standards (ERC-1155).

How does it handle NFT metadata?

The skill includes templates for off-chain IPFS-based metadata schemas and advanced examples for fully on-chain SVG/JSON metadata generation.

Can I implement secondary sale royalties?

Yes, it includes support for EIP-2981, which is the industry standard for signaling royalty requirements to compatible NFT marketplaces.

What are Soulbound Tokens in this context?

It provides code patterns to restrict the transfer function of a token, making it permanently linked to a specific wallet for identity or achievement purposes.

NFT Standards Implementation

API Development

Implements industry-standard NFT protocols including ERC-721 and ERC-1155 with advanced features like metadata management and royalty integration.

About

This skill provides comprehensive guidance and boilerplate for developing non-fungible tokens on EVM-compatible blockchains. It covers everything from basic minting strategies and batch transfers to advanced concepts like Soulbound Tokens (SBTs), dynamic metadata, and EIP-2981 royalty enforcement. It is an essential toolkit for developers building NFT collections, decentralized marketplaces, or on-chain gaming assets who need gas-optimized, secure, and marketplace-compatible smart contracts using battle-tested OpenZeppelin patterns.
