 # Swap SDK
 
-The missing peer-to-peer swap library for Ethereum and EVM compatible chains, powered by the [0x protocol](https://0x.org), written in TypeScript for web3 developers. Trade tokens (ERC20s), NFTs, and other collectibles (ERC721 and ERC1155) with just a few lines of code. Seriously, easily trade anything on Ethereum with this library.

 **🎉 Update 1/31/22: Swap SDK now supports 0x v4, check out the [docs](https://docs.swapsdk.xyz/0x-v4). 🎉**
 
 ## Overview
 
-tl;dr: NFT Swap SDK is the easiest, most-powerful swap library available on the EVM. Supports Ethereum and EVM-compatible chains (Polygon, Avalanche, BSC, etc..). Works in both browser and node.js. Written in TypeScript, built using the 0x protocol. With this library, you can build support for NFT marketplaces, over-the-counter (OTC) exchange, and/or peer-to-peer exchange.

 The NFT Swap SDK developed by [Trader.xyz](https://trader.xyz) offers swap support for ERC20s, ERC721s, and ERC1155s. Exchange NFTs for NFTs, NFTs for ERC20 tokens, or bundles of NFTs and tokens. This library provides the ultimate swap flexibility combined with a simple API surface area so you can be productive immediately and focus on building your web3 app.

 This is just one example. In reality, you can swap as many things as you'd like, any way you'd like. The underlying 0x protocol is extremely flexible, and the NFT swap library abstracts all the complexity away so you don't have to worry about protocol nuances.
