Are the contracts secure?

The skill utilizes battle-tested patterns from OpenZeppelin, the industry standard for secure smart contract development, to ensure best practices in access control and token logic.

What NFT standards does this skill support?

It provides full support for ERC-721 (Non-Fungible Tokens) and ERC-1155 (Multi-Token Standard), including extensions for URI storage, enumeration, and gas optimization.

Is gas optimization included?

Yes, the skill specifically includes ERC721A implementation patterns, which significantly reduce gas costs for batch minting multiple NFTs in a single transaction.

How does it handle NFT metadata?

The skill includes patterns for both off-chain metadata (hosted on IPFS/centralized servers) and fully on-chain metadata using Base64 encoding and SVG generation.

Can I implement secondary sale royalties?

Yes, it implements the EIP-2981 Royalty Standard, which allows you to set universal royalty percentages that are recognized by major NFT marketplaces.
