Can I create non-transferable 'Soulbound' tokens?

Yes, the skill includes specific implementation logic for Soulbound tokens (SBTs) by overriding the transfer hooks in the standard NFT protocols.

Can I implement on-chain metadata with this skill?

Absolutely. It provides templates for Base64 encoded on-chain metadata and SVG generation, as well as standard IPFS-based off-chain metadata.

Are the generated contracts compatible with OpenSea and Blur?

Yes, by following standard ERC-721/1155 specifications and EIP-2981 for royalties, the contracts are fully compatible with all major NFT marketplaces.

Does this skill support gas optimization for large collections?

Yes, the skill includes patterns for ERC721A, which is specifically designed to minimize gas costs during batch minting operations.
