What is DEX and how does it work?

what is DEX?

Decentralized exchanges, or DEXs, are peer-to-peer markets where cryptocurrency investors may conduct operations without entrusting their assets to an intermediate or administrator. These interactions are enabled by the use of smart agreements, which are automatic contracts constructed using code.

DEXs were designed to eliminate the need for any governing body to supervise and sanction deals conducted within a given exchange. Decentralized exchanges enable peer-to-peer (P2P) cryptocurrency trading. A peer-to-peer marketplace connects consumers and sellers of cryptocurrency. They are often non-custodial, which implies that users retain ownership of their wallet’s private keys.

A private key is a sophisticated way of encrypting that allows users to retrieve their currency. After login into the DEX using their private key, users may instantly view their crypto accounts. They will not be forced to enter any private data, such as addresses or names, which is ideal for those who value confidentiality.

Computerized market makers, for example, helped draw consumers to the decentralized finance, or DeFi, area and assisted significantly to its development. DEX organizers and wallet plugins fostered the rise of decentralized exchanges by reducing token prices, exchange fees, and movement, while also providing consumers with a better rate.


Cryptocurrency exchanges are an important source of stability for the worldwide crypto marketplace, supporting millions of dollars in daily trade activity. Prominent exchange systems keep expanding in accordance with the increasing need for digital assets, delivering asset custody, additional trading capabilities and features, as well as access to an expanding variety of digital assets as the market develops.

Order Book

Decentralized crypto exchanges and DeFi devices have several iterations. The initial generation of decentralized trading platforms, like traditional exchanges that are centralized, employ order books. These order books are used to keep track of all outstanding purchase and sell transactions for a certain commodity. The disparity between these rates affects the order book breadth and the current market price. This data is frequently maintained on-chain during transactions on DEXs with order books, while your money stay outside of the chain in your wallet. Most DEXs specialize on a certain financial product that is performed decentralized.

However, DEX systems that keep their order books outside the blockchain simply execute deals on the network so as to provide dealers with the advantages of centralized exchanges. Off-chain order books assist exchanges in saving money and speeding up while helping to ensure that deals are performed at the prices preferred by users.

The exchanges additionally enable users to make loans their cash to other traders in order to provide stretched trading possibilities. Borrowed money accumulate interest and are guaranteed by the exchange’s liquidation system, which ensures borrowers are paid even if dealers fail to fulfill their bets.

Below, some examples ae mentioned:

  • dYdX
  • Nash Exchange
  • Tomo DEX
  • ViteX
  • DDEX
  • Binance DEX
  • Loopring Exchange

Order books are no longer used to conduct transactions or determine prices on the upcoming wave of exchanges that are decentralized. To calculate commodity price, such platforms often use stability pool methods. These peer-to-peer trading platforms instantaneously conduct deals between users’ wallets – an action known as a swap by some. The total amount locked (TVL), or the value of assets held in the protocol’s smart contract, is used to rank the DEXs in this area.


Such as:

  • Uniswap
  • Curve
  • SushiSwap
  • Gnosis
  • Balancer
  • Bancor
  • Kyber
  • DODO

Benefits of using a DEX

  • Token accessibility
  • Privacy
  • Security threats have been reduced.
  • Decreased counterparty risk

Drawbacks of using a DEX

  • It is necessary to have certain expertise.
  • Risks associated with smart contracts
  • Token postings that have not been vetted
  • Decentralized exchanges are constantly changing.

How to know the best time for investing in cryptocurrencies?


Despite the fact that centralized exchanges account for the great bulk of market activity because they provide safety, governmental supervision, and frequently insurance, the emergence of DeFi has made room for the creation of decentralized crypto exchange methods and aggregating tools. Systems like as Uniswap, Curve, and Balancer demonstrate the possibility for straightforward, user-friendly systems which depend on liquidity standards instead of order books. The increasing number of additional protocols along with backing systems is anticipated to speed up as the DEX market grows.
