Can I create non-transferable Soulbound tokens?

Absolutely. The skill provides specific logic to override transfer functions, enabling the creation of permanent, non-transferable assets.

Is the code compatible with major NFT marketplaces?

Yes, all templates follow standard EIPs, including EIP-2981 for royalties, ensuring compatibility with OpenSea, Blur, and Rarible.

Does this skill support gas optimization?

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

Does it support on-chain metadata?

Yes, the skill includes examples of how to encode metadata and SVG images directly into the smart contract using Base64 encoding.
