Is gas optimization included for minting?

Absolutely. It features patterns for ERC721A, which significantly reduces gas costs during batch minting operations compared to standard implementations.

Can I create non-transferable tokens?

Yes, the skill includes templates for Soulbound Tokens (SBTs) by restricting the transfer functions within the smart contract logic.

Which NFT standards does this skill support?

It supports ERC-721 for unique non-fungible tokens and ERC-1155 for multi-token standards, which is ideal for gaming and semi-fungible items.

How does it handle NFT metadata?

It provides patterns for both off-chain metadata (stored on IPFS/Arweave) and fully on-chain metadata generated via SVG and Base64 encoding.

Does it support marketplace royalties?

Yes, it includes implementations for EIP-2981, ensuring compatibility with major marketplaces like OpenSea and Rarible for automated royalty payments.
