# 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

In summary, the key difference between ERC20 and ERC721 is that ERC20 is for fungible tokens and ERC721 is for non-fungible tokens.
