Which NFT standards are supported by this skill?

This skill provides comprehensive support for ERC-721 (unique assets), ERC-1155 (multi-token/semi-fungible), and the gas-optimized ERC-721A standard for batch minting.

Does this skill support non-transferable or 'Soulbound' tokens?

Yes, it includes implementation patterns for Soulbound Tokens (SBTs) by overriding the transfer hooks while maintaining standard-compliant minting and burning functionality.

How are secondary sale royalties handled?

The skill implements the EIP-2981 Royalty Standard, which provides a universal way for marketplaces like OpenSea and Rarible to calculate and distribute creator fees.

Can I create NFTs with on-chain metadata using Claude Code?

Yes, the skill includes specialized patterns for encoding SVG and JSON metadata directly into the smart contract using Base64 to ensure 100% on-chain persistence.
