WHAT IS A DECENTRALIZED EXCHANGE?
A decentralized exchange, also known as a DEX, is a peer-to-peer marketplace where crypto traders conduct transactions directly, without the need for an intermediary or third party. DEXs enable financial transactions that are not conducted by banks, brokers, or other third parties. Popular DEXs include Sushiswap and Uniswap, both of which use the Ethereum blockchain. Similarly, PancakeSwap is also a popular DEX built on Binance Chain. These decentralized funding tools enable a wide range of financial services directly from a compatible cryptocurrency wallet.
The transactions in DEXs are facilitated through the use of self-executing agreements written in code called smart contracts. Compared to traditional financial transactions which are opaque and run through intermediaries who offer very limited insight into their actions. On the other hand, DEXs offer complete transparency on the movements of funds and the mechanisms that facilitate exchanges. With no third party involved, DEXs reduce counterparty risk and can reduce systematic centralization risk in the cryptocurrency ecosystem.
HOW DO YOU WORK?
Since DEXs are built on blockchain networks that support smart contracts. Therefore, DEXs determine the prices of different cryptocurrencies algorithmically and use “pools of liquidity”. In these pools, investors lock up funds against interest-like rewards. DEXs are based on open-source code, which means anyone interested can see its code and how it works. It also means that existing code can be customized by developers to create new competing projects. So Uniswap’s code has been adopted by a variety of DEXs with “swap” in their names like “Pancakeswap” and “Sushiswap” and so on.

DEXs were created to remove the need for authorities or third parties to monitor trades conducted on a specific exchange. DEXs allow P2P cryptocurrency. P2P or peer-to-peer refers to a marketplace where sellers and buyers are in direct contact. Their transactions are uncustodial, which means users remain in control of their wallet’s private keys. A private key is a form of advanced encryption that allows users to access their cryptocurrencies. By logging into a DEX with their private keys, users can access their crypto assets instantly. You do not have to provide any personal information such as name or address etc.
There are three main types of decentralized exchanges.
- Automated Market Makers
- Order book DEX
- DEX Aggregators
All of this enables direct trading through smart contracts.
AUTOMATED MARKET MAKER
To solve the liquidity problem, an automated market maker system based on smart contracts was created. Popular decentralized exchanges have been built on prominent blockchains that support smart contracts. The most popular DEXs are based on the Ethereum blockchain. Similarly, these AMMs rely on blockchain-based services that provide information from exchanges and other platforms to set the price of traded assets, called “blockchain oracles.” These smart contracts then use pre-funded pools of assets known as liquidity pools. These pools are funded by other users, who are then entitled to the transaction fees charged by the protocol for executing a trade on that pair. These liquidity pools allow traders to execute orders or earn interest in a permissive and trusted manner.
ORDER BOOKS
Order books compile the records of all open buy and sell orders for specific asset pairs. It allows an exchange’s internal systems to match buy and sell orders. There is an on-chain order book and an off-chain order book. In the on-chain order book, each transaction is written to a blockchain. This includes not only the actual purchase, but also the request to purchase or cancel an order. With off-chain order books, all of this happens elsewhere, with only the last transaction being settled on the blockchain. Since orders are not stored on-chain, this issue can address some of the security issues of centralized exchanges, but is not as slow or costly as on-chain order books.
DEX AGGREGATORS
They use different protocols and mechanisms to solve the problems associated with liquidity. The two main goals of the DEX aggregator are to protect users from the price effect and reduce the chance of failed transactions.
ADVANTAGES OF USING A DEX
As DEX trades on facilitated by smart contracts, they offer strong guarantees that they will execute exactly as the user intended, without any interference from centralized third parties. So, DEXs offer strong execution guarantees and increased transparency of the underlying trading mechanisms.
DEXs offer a potentially limitless range of tokens, from the well-known to the weird and even completely unknown. This is because the Ethereum based tokens can be mined by anyone who can then create a liquidity pool for them. Furthermore, the coins are not kept in a central exchange, but in the user’s wallet with their private keys. So, theoretically, DEXs are less vulnerable to a hack.
Again, anonymity is a plus, as no personal information is required to use most popular DEXs. Similarly, DEXs also help improve financial inclusion. Because users can sign up directly with their wallet address, the onboarding process for a DEX is seamless and virtually instant compared to a centralized exchange.
CONCERNS
DEXs also come with a number of risks. For example, DEXs only work with crypto assets and not with fiat currencies like the US dollar or British pound. So, a person must have cryptocurrency assets in advance in order to use a decentralized exchange. Their interfaces are also much trickier, as navigating DEXs requires some expertise and the interfaces aren’t always easy or beginner-friendly.
A DeFi protocol is only as safe and secure as the smart contracts that power it. And the code may contain exploitable bugs that could result in loss of assets. Similarly, some DEXs have poor liquidity conditions, which can lead to large slippage and a miserable user experience. There is also a risk of fraud as many DEXs offer permissionless market creation (the possibility for anyone to create a market for any token). Therefore, the risks of buying malicious or low-quality tokens or even fake tokens can be much higher than with centralized exchanges.
