What is a Decentralised Exchange, and How do I use it?

A decentralised exchange (DEX) is a cryptocurrency trading platform that does not rely on a third-party intermediary to facilitate trade. Instead, it operates as a distributed ledger technology-based computer network that allows users to directly exchange digital assets without passing through an intermediary. The DEX model has become increasingly popular in recent years due to its potential for increased security, privacy, and speed of transactions.

Understanding how a DEX works are essential, and traders should note the differences between traditional and decentralised exchanges. Traditional exchanges are usually controlled by one central entity that oversees all aspects of the transaction process, including the fees charged for each trade and the amount of money settled at any given time. All exchange users must trust the central authority to handle their funds securely and correctly.

In contrast, decentralised exchanges do not rely on a single entity. Instead, they are connected by a distributed ledger technology, such as blockchain or similar protocols. This connection means that all transactions are managed by multiple nodes, allowing for increased security and faster processing times without relying on any single point of failure. As a result, users can trade directly with each other without having to involve a third-party intermediary or transfer their funds through a go-between.

DEX and cryptocurrencies

A DEX is relatively straightforward, and users can easily buy and sell cryptocurrencies. However, certain aspects should be considered when trading on a decentralised exchange. Firstly, users must conduct their due diligence on any new asset they wish to invest in and the trading platforms themselves.

This due diligence includes researching the team behind any project or platform involved in the transaction process, reading reviews from other traders, and ensuring that the terms of use associated with the exchange meet their needs. Additionally, it is essential to ensure that all transactions involve tokens listed on recognised cryptocurrency exchanges such as Binance or Poloniex before engaging in any trades.

As with most things related to cryptocurrency trading, security should always be a top priority when using a DEX. It is worth taking the time to try and understand the security features associated with each platform, such as two-factor authentication or cold storage wallets, to ensure that funds remain safe and secure at all times. Additionally, keeping track of any fees associated with trades is essential, as they can quickly add up if not managed properly.

Decentralised exchanges are an increasingly popular way to buy crypto in the UAE without relying on a third-party intermediary. While they offer increased levels of security and privacy compared to traditional exchanges, users should still take their time to conduct due diligence before engaging in any trades and monitor fees accordingly. Ultimately, by utilising a DEX correctly, users can enjoy a more convenient and secure way of trading cryptocurrencies.

How to use a DEX

Once you have chosen a suitable DEX, it is time to deposit your funds into your wallet and start trading. You can do this through an in-app process or by sending Bitcoin, Ethereum or other compatible tokens directly from your wallet. It is important to note that some decentralised exchanges may also require users to complete KYC (Know Your Customer) procedures before they can start trading.

Once the funds have been deposited, you can begin trading by selecting the trading pair you choose, which usually pairs two tokens, such as Bitcoin and Ethereum. However, more exotic options may also be available. Once you have chosen a pair, enter how much of each token you wish to buy or sell and click “Confirm”.

Your order will then show up on the order book, where it will remain until someone else decides to fill your order. You can cancel an open order anytime, but doing so may incur fees depending on your exchange. As with any form of trading, risk is always involved, and users should only invest what they can afford to lose.


A decentralised exchange is an integral part of the cryptocurrency trading landscape and provides users greater control over their funds while offering improved security compared to traditional exchanges. As such, they are an ideal choice for anyone looking to get involved in digital asset trading without relying on third-party intermediaries or fiat currencies. However, it is essential to ensure that all due diligence is conducted before engaging in any trades and to keep track of fees associated with each transaction. Users can enjoy a more secure and convenient way of trading cryptocurrencies on a decentralised exchange by taking these steps.
