Can I use this for on-chain metadata?

Absolutely. The skill provides templates for both IPFS-based off-chain metadata and Base64-encoded on-chain SVG/JSON metadata generation.

Does this skill support gas optimization for minting?

Yes, it includes specific implementation patterns for ERC721A, which significantly reduces gas costs for users during batch minting operations.

Is it compatible with OpenSea and other marketplaces?

Yes, the contract implementations follow industry-standard protocols and include EIP-2981 for seamless royalty enforcement across major NFT platforms.

Does it support non-transferable or 'Soulbound' tokens?

Yes, it includes patterns to restrict the _beforeTokenTransfer hook, enabling the creation of Soulbound Tokens (SBTs) for identity or achievements.

Implements industry-standard NFT protocols including ERC-721 and ERC-1155 with optimized minting and metadata patterns.

This skill provides specialized knowledge for developing robust non-fungible token (NFT) ecosystems on Ethereum and EVM-compatible chains. It covers the full lifecycle of NFT development, from writing gas-optimized smart contracts using OpenZeppelin and ERC721A to implementing complex features like EIP-2981 royalties, soulbound tokens, and dynamic on-chain metadata. Whether building a high-volume generative art collection, a gaming inventory system, or a decentralized marketplace, this skill ensures adherence to security best practices and compatibility with major platforms like OpenSea and Blur.
