A centralized exchange requires preliminary registration, verification, loading funds to the balance and, in some cases, passing double identification. In addition, fees for payment transfers are possible, and withdrawal to some networks is limited. The exchanger allows you to convert directly, bypassing the complex logic of interfaces. It is enough to select the desired rate, specify the wallet address, confirm the application and transfer funds. Such exchange offices are convenient when working with specific currency pairs, for example, ethereum - solana.
