Abstract:
A Decentralized Crypto Exchange is a place where people can go to trade cryptocurrencies without
an intermediary. A DEX, lets people trade directly from their crypto wallets. The exchange doesn’t
take control of their private keys or act as an intermediary. Instead, it uses smart contracts(self-
executing programs) to facilitate peer-to-peer exchanges. A decentralized exchange (DEX) lets
crypto holders remain pseudonymous and keep control of their crypto wallet’s private key. The
idea behind a DEX is ”disintermediation,” which means removing middlemen to allow regular
people to do business directly with each other. A DEX doesn’t offer custody of users’ crypto
assets. Instead, users directly hold all their assets in their wallets at all times. The exchange is
implemented with smart contracts on an Ethereum blockchain and deployed on an Ethereum test
network. In addition to implementing transactions between individual users, it also allows trans-
actions among multiple users.
