Does it cover metadata storage and hosting?

Yes, it provides code patterns for both off-chain (IPFS/Arweave) and fully on-chain metadata handling for permanent assets.

Are soulbound tokens (SBTs) supported?

Yes, it includes logic for non-transferable tokens suitable for reputation, identity, or certification systems.

Does this skill support gas optimization for large collections?

Yes, it includes implementation patterns for ERC721A to significantly minimize gas costs during batch minting operations.

Can I implement royalties with these templates?

Absolutely, it provides EIP-2981 standard implementations for on-chain royalty enforcement across major NFT marketplaces.

Is the code compatible with major NFT marketplaces?

Yes, the patterns follow the metadata and interface standards required for compatibility with OpenSea, Rarible, LooksRare, and Blur.
