Decentralised Exchange [Advantages and Drawbacks]

Decentralised Exchange [Advantages and Drawbacks] main

Decentralisation is a cornerstone of the blockchain technology ideology. Decentralisation—the absence of a central third-party mediator, such as a bank or financial institution—shifts power from a few to many. It’s also changing the way many traditional financial services function.

Despite this, some investors have been restricted to investing in digital assets via centralised exchanges that don’t conform with the ecosystem’s primary idea up until recently. Decentralised exchanges were born as a result of this inconsistency and offered a decentralised platform for the exchange of assets without the need for users to place their faith in a third party.

How it works

Direct peer-to-peer cryptocurrency transactions through a safe and secure online platform without a middleman are the features of a decentralised exchange (DEX). Traditional centralised exchanges employ a third-party business (e.g. bank, trading platform, government agency) to hold user money and monitor the safety and transfer of assets between two parties.

In a decentralised exchange, the third party is replaced by a blockchain or distributed ledger. Users maintain full control over their assets by transferring crucial functions onto the blockchain, which removes the risk of a single point of failure. Automated code is used by DEXs to do market transactions, although there are a variety of order fulfilment options with varying degrees of decentralisation. This very feature lured a lot of curious investors into the concept of the blockchain even more. It later paved the way for trading, which is safer, reliable, and seamless on websites like

Decentralised exchanges, like digital currencies, were born as a reaction to outdated financial systems that exposed their users to the inherent hazards of a centralised system, such as inadequate security, technological difficulties, and a lack of transparency.

Pros of Decentralised Exchanges

Cryptocurrency lovers and followers have embraced decentralised exchanges for a variety of reasons.

DEXs are untrustworthy, which means that users’ finances, privacy, and limited personal data are safe. Users of decentralised exchanges may access a DEX without creating an on-exchange account, undergoing identity verification, or providing personal information.

Decentralised exchanges are less vulnerable to hacking since users do not have to transmit their assets to the exchange. As a result, the absence of Know Your Customer (KYC) cryptocurrency standards and regulations makes DEXs ideal for preventing price manipulation or faking trade volume.

New and obscure coins may now be traded on a DEX or a DApp (decentralised application) that was previously impossible to swap. Smaller and less well-known tokens might be difficult to trade on centralised exchanges since they only offer a few projects and most only support the most prominent cryptocurrencies.

Cons of a Decentralised Exchange

Despite the many advantages of decentralised exchanges, they also have a few limitations.

Instead of being able to retrieve monies that have been stolen or lost, DEXs don’t have a central clearinghouse that can do this. When a user’s account is hacked, and their private key is lost, they are left with no way to restore their data or get their money back. If you lose your private key, you won’t be able to get in touch with the customer care staff. Refunds are impossible on the blockchain since all transactions are processed and kept in smart contracts, which have no owners or overseers. As a result, users lose access to their money.

To have more instruments, currency pairings, and order types available, many traders choose centralised systems. Because they are young and have limited liquidity, decentralised exchanges tend to have lesser liquidity than centralised platforms. However, to produce greater liquidity, they must recruit new customers.

The network’s miners, not the exchange, determine how quickly transactions are processed on a blockchain network.

Given that decentralised exchanges have just recently been made operational, they tend to concentrate on the execution of basic buy and sell transactions. Most DEXs do not provide sophisticated trading features like stop losses, margin trading, or lending.

DEXs have been plagued by the same network congestion difficulties that their underlying blockchain networks, such as Ethereum, have been plagued with. Ethereum’s first blockchain iteration, like those of other blockchains, was designed to operate safely at a smaller size until scaling solutions were incorporated later. For now, DEXs are still constrained by the first-layer network transaction limits, although a whole new network with massively scalable solutions has been in development since 2018.

Types of Decentralised Exchanges

As first-layer blockchain scalability is limited, full decentralisation is more of a mindset than a rule of thumb. In reality, most decentralised exchanges are semi-decentralised, relying on their servers and off-chain order books to store data, as well as other programs or organisations for the exchange of user assets. Semi-decentralised exchanges may be vulnerable to government regulation because of their dependence on centralised components. Most significantly, users are in charge of their cash since they have access to private keys.

Although DEXs are constantly evolving and working with other DApps across chains, most of the time, they only run on a single blockchain. This feature is typical of the majority of decentralised exchanges, which employ smart contracts to execute orders and do not store the cash of its customers.

Order modifications and cancellations are handled entirely on-chain in certain decentralised exchanges. Because it does not rely on a third party to handle any orders at any time, this is the most decentralised and open procedure possible from a philosophical standpoint. The problem with this method is that it’s not particularly practical.

Decentralised exchanges using off-chain order books maintain some degree of decentralisation while being less decentralised than on-chain exchanges. The order book is managed by a centralised authority rather than being kept on the blockchain, as is the case with off-chain orders. The DEX’s non-custodial methodology might be used to front-run or falsify orders by an entity with access to the order books.

Final thoughts

To purchase and sell bitcoin, consumers do not have to give over their assets to a third party via decentralised exchanges. For now, investors may select between several kinds of DEXs that provide various degrees of security, privacy, and efficiency, even if complete decentralisation is still a long way off.

Decentralised exchange (DEX) development and user acceptance will become more important as DEXs seek to leech liquidity from existing marketplaces.
