Can I create non-transferable tokens?

Yes, the skill provides templates for 'Soulbound' tokens (SBTs) by correctly overriding internal transfer hooks to prevent secondary market trading.

Are the contracts compatible with OpenSea and Blur?

Yes, the implementations follow the standardized metadata schemas and royalty protocols (EIP-2981) required for full compatibility with major NFT marketplaces.

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.

How is NFT metadata handled?

It supports both off-chain IPFS-based metadata patterns for storage efficiency and fully on-chain SVG/JSON metadata generation for permanence.

Implements industry-standard NFT protocols and advanced token features for Ethereum-compatible blockchains.

About

This skill provides comprehensive guidance for developing non-fungible tokens using ERC-721 and ERC-1155 standards. It covers essential patterns including metadata management (on-chain and IPFS), gas-optimized batch minting with ERC721A, royalty enforcement via EIP-2981, and the creation of specialized assets like soulbound or dynamic NFTs. Ideal for developers building digital collectibles, gaming assets, or decentralized marketplaces, it ensures code follows OpenZeppelin best practices and is ready for marketplace integration.
