Can I create non-transferable tokens with this skill?

Absolutely. The skill provides a 'Soulbound Token' (SBT) pattern that overrides transfer hooks to ensure tokens remain tied to the original recipient.

Does this skill support gas-efficient batch minting?

Yes, it includes implementations for ERC721A and ERC-1155, which are optimized to reduce gas costs during high-volume minting operations.

Is it compatible with OpenSea and other major marketplaces?

Yes. By following standard metadata schemas and implementing EIP-2981 for royalties, the contracts generated are fully compatible with OpenSea, LooksRare, and Blur.

Does it support on-chain metadata for fully decentralized NFTs?

Yes, it includes patterns for generating Base64 encoded JSON and SVG images directly within the smart contract for 100% on-chain persistence.

Developer Tools

Implements industry-standard NFT protocols including ERC-721 and ERC-1155 with advanced features like royalties, gas-optimized minting, and metadata management.

About

This skill provides a comprehensive toolkit for building blockchain-based digital assets using industry-standard Solidity protocols. It enables developers to implement non-fungible (ERC-721) and multi-token (ERC-1155) contracts with best practices for metadata (IPFS and On-chain), royalty enforcement (EIP-2981), and gas optimization via ERC721A. Whether you are building a digital art collection, a complex gaming inventory system, or non-transferable soulbound identity tokens, this skill provides the implementation patterns needed for secure, marketplace-ready deployments.
