Types of Decentralized Exchanges
Decentralized Exchanges (DEX)

What are Decentralized Exchanges?

Decentralized exchanges allow users to swap cryptocurrency assets by using smart contracts and on-chain transactions to reduce or eliminate the need for an intermediary. Instead of having to go through an exchange where you have to identify yourself and are subject to the exchanges security measures, a decentralized exchange gives you 100% freedom.

How to trade on a Decentralized Exchange

  • Buy Ether on a crypto exchange or peer-to-peer exchange

  • Get an Ethereum wallet (Argent, Authereum or Metamask are our favourites)

  • Withdraw your Ether from the crypto exchange to your Ethereum wallet

  • Go to the decentralized exchange’s website and connect your wallet

  • Start trading

Things you should know before starting to trade on a Decentralized Exchange

  • Always try things with small amounts of money before using larger amounts.

  • You need Ether (ETH) to pay for gas to transact on the Ethereum network.

  • Gas costs can be quite high. Download the Ethereum Gas Station Chrome Extension to monitor gas prices and get real-time suggestions on how much to pay.

  • Some Ethereum wallets (e.g Metamask) require you to write down a seed phrase. Write it down safely and keep it somewhere secure!

  • You can only trade Ether and Ethereum tokens on Decentralized Exchanges, not any cryptocurrency (Bitcoin, Litecoin etc.)

How do Decentralized Exchanges work?

In some ways decentralized exchanges work similarly to centralized exchanges in that they connect buyers and sellers wanting to exchange assets, in an automated way. However, there are many differences, ranging from the characteristics we mentioned above (non-custodial, on-chain etc.) but also how orders are matched. Many decentralized exchanges use a model called the Automated Market Maker (AMM) model as opposed to an Order Book Model (OBL). This is due to the fact that order books need very fast transaction speeds, which Blockchains currently can’t deliver.
