Nft Standards

Implements complete ERC-721 and ERC-1155 contracts with OpenZeppelin imports, proper enumeration, and URI handling. Generates both off-chain IPFS metadata structures and on-chain SVG generation with Base64 encoding. Includes EIP-2981 royalty implementation, soulbound token mechanics that block transfers, and batch minting with supply caps. The code examples are production-ready with proper access controls and overflow protection. This covers the full NFT development cycle from basic minting to marketplace integration, though you'll still need to handle the frontend wallet connections and IPFS pinning separately.
