Implement NFT standards (ERC-721, ERC-1155) with proper metadata handling, minting strategies, and marketplace integration. Use when creating NFT contracts, building NFT marketplaces, or implementing digital asset systems.

TL;DR

Implement ERC-721 and ERC-1155 NFT standards with metadata handling and minting.

What Is It

ERC-721 for unique, non-fungible tokens
ERC-1155 for multiple types of fungible and non-fungible tokens
Metadata standards using IPFS or on-chain storage
Support for royalties, dynamic traits, and soulbound tokens

Key Features

Mint tokens with supply limits and price controls
Support for off-chain (IPFS) and on-chain metadata
Royalty and revenue sharing capabilities
Soulbound tokens (non-transferable)
Dynamic and evolving NFT traits
Batch minting and burning for efficiency
Metadata validation and standardization
Marketplace integration via token transfer and URI support

How to Use

1.Choose ERC-721 for unique assets like art or collectibles
2.Use ERC-1155 for multiple item types like game items
3.Store metadata on IPFS or implement on-chain metadata
4.Implement minting with supply caps and payment validation
5.Set up royalty and revenue sharing logic
6.Integrate with marketplaces via token transfer and URI access

Guardrails & Gotchas

MUST validate supply limits to prevent over-issuance
MUST ensure proper metadata URI format and accessibility
FORBIDDEN to allow unlimited minting without caps
MUST handle unauthorized transfers with proper approvals
MUST support royalty payments for creators
MUST prevent minting beyond max supply
