DEX - Part 1

You may have heard of Binance and FTX from the news headlines. They are called Centralized Exchanges (CEX) since one company operates them and reaps profit from operating them. What is a Decentralized Exchange (DEX)? A decentralized exchange (DEX) is a peer-to-peer marketplace where users can trade cryptocurrency directly with each other, without using an intermediary. Popular DEXs include Uniswap, SushiSwap, Pancake Swap, DODO, and Curve. In Part 1 of the DEX course, we will learn to build a liquidity pool and implement the “add liquidity” functionality.
