How does it handle NFT royalties?

It implements the EIP-2981 Royalty Standard, ensuring that royalty information is consistently communicated to supporting marketplaces.

Can I create non-transferable tokens with this skill?

Yes, it provides implementation patterns for Soulbound Tokens (SBTs) that restrict transfers, ideal for credentials and achievements.

Does it support on-chain metadata?

Yes, the skill includes patterns for generating Base64 encoded JSON and SVG data directly on the blockchain for fully decentralized NFTs.

Does this skill support gas optimization for large collections?

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