# ERC20 vs ERC721 ERC20 and ERC721 are two different standards for creating tokens on the Ethereum blockchain. **ERC20** ERC20 is a standard for creating fungible tokens, meaning that each token is identical and interchangeable with another. They are like currency and can be used to represent assets such as a company's stock or a currency and are used in Defi. Some examples of ERC20 tokens are: * Binance Coin (BNB) * Tether (USDT) * Chainlink (LINK) * Polkadot (DOT) * Uniswap (UNI) * Wrapped Bitcoin (WBTC) **ERC721** ERC721 on the other hand, is a standard for creating non-fungible tokens, (NFT) meaning each token is unique and cannot be exchanged for another token on a 1-to-1 basis. They are like collectibles and can be used to represent assets such as art, real estate, or in-game items. Some examples of ERC721 tokens are: * Bored Ape Yacht Club * Doodles * CryptoKitties * CryptoPunks *(above Doodles collection, the famous Doodles)* In summary, the key difference between ERC20 and ERC721 is that ERC20 is for fungible tokens and ERC721 is for non-fungible tokens. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
