DDEX is an application for trading cryptocurrencies on the exchange of the same name. It was the first project based on the open Hydro protocol (the developers themselves call Hydro a “fork” of 0x). DDEX has an established asset trading venue and two smartphone applications for iOS and Android.

Application of the first decentralized exchange on the Hydro Protocol

DDEX is designed to ensure the liquidity of Ether and ERC-20 tokens directly from user wallets, such as MetaMask, Ledger, and Brave. In addition, the application collaborates with wallet projects such as Cipher, Toshi, Trust, and Dapp Browser. Therefore, users can sign up with one of the already existing wallets.

In the case of creating a new account in the DDEX application, users need to come up with a wallet nickname of Latin letters and numbers. After that, a seed phrase of 12 random words will be generated, which will help restore access to the exchange in various emergency cases. This phrase must be kept in a protected place so that no one but the user has access to it. To complete the registration, which also serves as the verification of user data, it is necessary to enter words from a previously generated set.

It is important to note that if a user works on the exchange through the DDEX application, then all the data is stored on the device, and not on the exchanger itself. Users must also confirm that a backup copy of the recovery phrase has been made. The user is also informed that if the application is removed, all wallets will be deleted as well. This is done for protection and preventing theft of funds.

The DDEX application itself will be accessed via the Touch ID. Therefore, when creating an account, the user must put the finger on the scanning device on the smartphone.

The decentralized exchange DDEX exists at the expense of a commission for the processed transactions. The Wrapped Ethereum token was created for this, or WETH for short. To get WETH, users must exchange Ether for the coin. After that, it will be possible to trade on the DDEX exchange.
