Fees charged from the transactions are needed to support the networks that run the coin/token. This fee doesn’t go to us, it goes to reward miners (thereby ensuring that the transaction is logged into the blockchain in a timely fashion) and to support the Ethereum network itself.
As the new coins are implemented, each coin is a subject to its own transaction fee that is paid to their respected networks.
Off-chain transactions, i.e. transactions made between Freewallet customers, are not subjected to any fees.
We kindly ask you to keep in mind that network fees may vary due to the current high volatility of cryptocurrency markets. You can always see the fee amount in our app or in web wallet, when you making a transfer.
