How does it handle NFT metadata?

It supports both off-chain IPFS-based JSON metadata and fully on-chain SVG generation using Base64 encoding for 100% decentralized storage.

Can I create non-transferable tokens?

Yes, the skill provides templates for Soulbound Tokens (SBTs) by overriding transfer hooks to prevent movement between wallets while allowing for burning.

Does this skill support gas optimization?

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

Is it compatible with major marketplaces?

Absolutely. It follows EIP-2981 for royalty enforcement and uses standard metadata schemas recognized by OpenSea, Blur, and Rarible.
