Transaction Fees
A transaction fee is a cost paid in Flow by the payer account and is required for a transaction to be included in the Flow blockchain. Fees are necessary for protecting the network against spam, and infinite running transactions and to provide monetary incentives for participants that make up the Flow network.
A transaction fee is paid regardless of whether a transaction succeeds or fails. If the payer account doesn't have sufficient Flow balance to pay for the transaction fee, the transaction will fail. We can limit the transaction fee to some extent by providing the gas limit value when submitting the transaction.
