# Buy exchange

## Step one

FIRST PREPARE THE FON MINER FEE AND THE CURRENCY USED TO BUY THE TRANSACTION, AND ENTER ROSSWAP THROUGH THE DECENTRALIZED WALLET BROWSER TO THE "EXCHANGE" INTERFACE.

After entering the ROSSWAP page, select the currency you need to buy, enter the amount you need to buy, and if the prompt "Allow to call authorization" appears, follow the prompt to complete the authorization.
