DEX – Why the decentralized exchange is so interesting

CoinMarketCap called 2019 the year of decentralized exchanges, abbreviated DEX (Decentralized Exchange). The trend continues to this day and continues. How dodecentralized exchanges (dex) work and how will they change the market? Is the technology even ready to replace traditional exchanges?

Decentralized exchanges: a necessary evil?

Cryptocurrencies like Bitcoin were developed as peer-to-peer payment systems. They were meant to allow users to transfer value without relying on a central authority or intermediary. The distributed network and often anonymous miners provide transaction processing and security.

The main goal of cryptocurrencies was to give users back control over their money. Nevertheless, decentralization has not reached all areas related to cryptocurrencies. Users have had to turn to Exchanges to trade or purchase cryptocurrencies. However, these exchanges are mostly centralized.

Centralized exchanges are easy to use, easily accessible and offer advanced trading features that make trading easier. However, they also pose a security risk. Almost every few months, hacker attacks on centralized Exchanges make headlines.

Among the largest were the attack on Coincheck in January 2018, in which US$533 million was stolen, and the attack on Mt. Gox, with over US$460 million stolen in February 2014.

Despite the significant security risks, users were left with little choice but to trade their crypto assets on centralized exchanges. Many services and everyday items cannot yet be bought with cryptocurrencies.

On the other hand, traders must first use fiat currencies to be able to buy cryptocurrencies. How can trading on exchanges be made more secure? The solution could be decentralized exchanges or DEXs for short.

What is decentralized exchanges (DEX)?

The decentralized exchange is a type of marketplace that does not rely on a third-party provider to hold customers’ funds. Trading takes place in the form of transactions directly between customers via a peer-to-peer network.

This system contrasts with the centralized model where users deposit their funds and the exchange issues an ‘IOU’ that can be freely traded on the platform. When a user asks to withdraw their funds, they are converted into the cryptocurrency they represent and sent to their owner.

A basic distinction is made between two currency models:

More and more companies and especially centralized exchanges are responding to the new model by setting up their own DEX platforms. On 18 April 2019, one of the most successful Exchanges Binance released its decentralized exchange Binance Chain. The exchange then officially went online on 23 April 2019, after all Binance tokens were transferred to Binance Chain.

A lot has happened since then, with many new decentralized exchanges emerging. Here are the most successful three DEXs:

The DEX 0x

0x stands for Over the Counter (OTC) and describes the trading of tokens directly and without fees with other investors. Each investor can generate his order himself, place it on the blockchain and sign it cryptographically.

Only the order is placed on the blockchain; the price negotiation between buyer and seller can take place via the usual communication channels.

Cryptocurrencies can be exchanged on the decentralized exchange 0x via peer-to-peer. The DEX is based on the Ethereum project and the associated coin is the 0x of the same name with the abbreviation ZRX.

The ZRX token from Ox

ZRX is a classic example of an ERC-20 token and enables the exchange of Ethereum-based assets. Other exchanges can access the 0x platform via an interface and integrate the services into their own services.

The token has three main functions:

  • Coordinates the network
  • Provides liquidity to the network
  • Encourages feedback from users
  • Advantages at 0x are the fast digital contracts and low transaction costs. The crypto exchange is also fully decentralized, meaning users store their money locally, making it safe from hackers.

0x is also able to use ERC-721 tokens and uses an open-source infrastructure. In addition, 0x is just a protocol, trades can be easily and quickly done with a Chrome Extension like Metamask.

Trades are conducted via smart contracts, which users can freely use via decentralized apps. Famous backers of DEX 0x include Polychain Capital, Pantera Capital, Jen Advisors from China and FBG Capital.

Around 24 million US dollars were raised in the first ICO. Owners of the tokens receive the ZRX token for providing their liquidity; it is also linked to governance rights at the same time.

Cooperation with Polygon

0x has emerged mainly due to the need for existing high fees of central exchanges. However, another reason for the emergence is the fact that ERC-20 tokens cannot be exchanged with every token on all exchanges. Moreover, many new tokens are only tradable on major crypto exchanges months after their launch. Consequently, there are idle periods to bridge.

There are currently almost 300,000 individual traders registered on 0x. So far, the platform has handled over 1.5 million trades with a volume of more than 27 billion US dollars.

In the meantime, the Binance Smart Chain is also connected via API and at the end of May, Polygon was selected for further cooperation after a survey among users.

The 0x protocol is a middleware protocol that sits between the blockchain consensus layer and the user layer. Polygon now processes three times as many transactions as Ethereum.

The DEX Uniswap

The decentralized trading platform based on the Ethereum blockchain is designed for swapping token pairs. Current liquidity is around $4.5 billion and over 72,000 users have provided their assets as liquidity to the network.

Uniswap does not use native tokens and all fees go to the liquidity providers. This is currently up to a 0.5% transaction fee per trade. The Uniswap Coin UNI is limited to 1 billion units and is a pure governance token.

Users can deposit using PayPal, Skrill, Neteller or a credit card and then have the immediate ability to invest in UNI. The open-source infrastructure around Uniswap gets fantastic price forecasts from crypto experts because the protocol is user-friendly, cheap and low-risk.

Experts see a bright future for Uniswap

The success proves the developers right because the Uniswap chart shows the course of the last months and there it is going steeply upwards.

Uniswap’s trading prices are set by an algorithm that also prevents imbalances from arising and inflation from taking hold. Via collective pools, liquidity providers have the option of contributing their deposited assets as liquidity to the network.

Arbitrage trading is popular with users, trading between platforms for as much profit as possible. Uniswap provides analysis tools and token lists for this purpose. As a decentralized aggregator, Uniswap thus also offers liquidity for many DEX aggregator platforms.

In the future, Uniswap’s main goal is to speed up payments and reduce transaction costs. To this end, the company also wants to achieve lower latency times.
