Does it handle on-chain metadata for generative art?

Absolutely. It includes patterns for generating Base64-encoded JSON and SVG data directly on the blockchain, ensuring your NFT metadata is permanent and decentralized.

Does this skill support gas optimization for minting?

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

Are the smart contract templates secure?

The skill follows industry best practices by utilizing OpenZeppelin's battle-tested libraries, ensuring high security and adherence to established Ethereum Improvement Proposals (EIPs).

Can I implement secondary sale royalties?

Yes, the skill provides templates for EIP-2981, the universal standard for on-chain royalty information that is recognized by major marketplaces like OpenSea and Rarible.
