This skill provides comprehensive guidance for implementing NFT standards in Solidity. It covers ERC-721 and ERC-1155 token contracts, metadata best practices (on-chain and IPFS), royalty implementation (EIP-2981), soulbound tokens, dynamic NFTs, and gas-optimized minting with ERC721A.

A comprehensive token integration security analyzer based on Trail of Bits' checklist. Guides users through systematic analysis of ERC20/ERC721 tokens for conformity issues, weird token patterns (fee-on-transfer, rebasing, missing returns, etc.), owner privileges, and integration safety concerns. Provides structured report templates and checklists.
