What are the advantages of such transactions?
Speed
Instant transfers are completed much faster than regular transactions, no need to wait for any confirmations.
Costs
Instant transfers are not subject to the fees miners are paid for their services in verifying the ledger. With Instant transfers, you can make lots of very small transfers.
Naming
With Instant transfers, you can send coins to other Freewallet users simply by referencing their User ID or email instead of using the address.
Privacy/Anonymity
Because Instant transfers do not happen in the blockchain, they are not public. But this also can be a disadvantage, as there is no ability to publicly confirm the transactions.
Transfers between Freewallet customers (in one chain) are instant as they are recorded internally in our database.
Use wallet address, email, or User ID to make quick no-fee transactions.
