How does it handle marketplace royalties?

It implements the EIP-2981 Royalty Standard, which allows your contract to signal royalty percentages to all compatible NFT marketplaces automatically.

Is it compatible with OpenSea and other major platforms?

Yes, all provided code follows the standard metadata and interface requirements used by OpenSea, Blur, Rarible, and LooksRare.

Can I implement on-chain metadata with this skill?

Absolutely. The skill provides templates for encoding SVG data and JSON metadata directly into the smart contract using Base64 libraries.

Does this skill support gas optimization?

Yes, it includes patterns for ERC721A and batch minting to significantly minimize transaction costs for users during minting events.
