Fees applied to a transaction are sent to support the networks that run the coin/token. This fee doesn’t go to us, it goes to reward the miners (to ensure that the transaction is logged into the blockchain in a timely fashion) and to support the Ethereum network itself.
When transferring from a Freewallet account to another Freewallet account (within one chain), the transactions occur off the blockchain.
What are the advantages of these transactions?

Speed

Instant transfers are completed instantly, no need to wait for confirmations.

Costs

Instant transfers are not subject to the fees paid to the miners for their services – verifying the ledger. With Instant transfers, you can make lots of small transfers.

Naming

With Instant transfers, you can send coins to other Freewallet users by referencing their user ID or email instead of typing the address.

Privacy/Anonymity

Because Instant transfers do not take place on the blockchain, therefore, they are not public. But this can be a disadvantage as there is no ability to publicly confirm the transactions.

Freewallet Instant transfers are available for all Freewallet currencies.
