Can I create non-transferable NFTs?

Absolutely, the skill provides templates for Soulbound Tokens (SBTs) which restrict transfers to ensure assets stay with the original owner.

How does it handle NFT metadata?

It provides solutions for both off-chain metadata (IPFS) and fully on-chain metadata generation using Base64-encoded JSON and SVG assets.

Does this skill support gas optimization?

Yes, it includes 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 code follows standard metadata schemas and EIP-2981 royalty patterns required by major marketplaces like OpenSea, Blur, and Rarible.
