Can I create soulbound tokens?

Yes, it includes logic to override transfer functions to create non-transferable 'soulbound' tokens suitable for identity and credentials.

Does this skill support gas optimization?

Yes, it includes implementation patterns for ERC721A, which significantly reduces gas costs for batch minting operations compared to standard ERC-721.

Is it compatible with OpenZeppelin?

Absolutely. It utilizes industry-standard OpenZeppelin libraries for secure, battle-tested contract logic and access control.

How does it handle NFT metadata?

The skill provides patterns for both off-chain metadata (IPFS/Arweave) and fully on-chain metadata using Base64-encoded JSON and SVGs.

E-commerce Solutions

Implements and optimizes ERC-721 and ERC-1155 NFT standards with support for royalties, soulbound tokens, and gas-efficient minting.

About

This skill provides specialized guidance for developing non-fungible tokens on Ethereum and EVM-compatible blockchains. It covers the full lifecycle of NFT development, from basic ERC-721 and multi-token ERC-1155 implementations to complex patterns such as on-chain metadata generation, EIP-2981 royalty enforcement, and ERC721A for high-volume gas optimization. Whether building a generative art collection, gaming assets, or soulbound identity tokens, this skill ensures developers follow security best practices and maintain marketplace compatibility with platforms like OpenSea and Blur.
