Does it handle on-chain metadata?

Yes, it provides examples for both off-chain IPFS-based metadata and fully on-chain SVG/JSON generation for permanent, decentralized asset storage.

Can I create gas-efficient collections with this skill?

Absolutely. The skill provides patterns for ERC721A, which significantly reduces gas costs for users minting multiple NFTs in a single transaction.

Does this skill support marketplace royalty standards?

Yes, it includes implementation details for EIP-2981, the industry standard for on-chain royalties compatible with major marketplaces like OpenSea and LooksRare.

Can I create non-transferable tokens?

Yes, the skill includes specialized logic for Soulbound Tokens (SBTs), which are ideal for digital identities, certifications, and non-transferable memberships.
