Overview
Unlike ERC-20 tokens, which are identical, each ERC-721 token is unique. This standard allows for the creation of digital assets that have distinct characteristics and can be owned individually.
Use Cases
- Digital Art: Unique pieces of artwork.
- Collectibles: Digital trading cards or items (e.g., CryptoKitties).
- Real Estate: Representing ownership of physical or virtual land.
Key Feature
Each token has a unique tokenId that distinguishes it from every other token in the same smart contract.
