Fee
blockchain · economics
Value paid under network rules or policy to submit, execute, relay, or include a blockchain transaction.
- Also known as
- transaction fee
A transaction fee is the value a transaction makes available for processing or block inclusion. In a UTXO transaction it is usually the input value minus the created output value; account-based systems may calculate fees from gas, resource units, base fees, tips, or other protocol rules.
Wallets estimate fees from local policy, recent blocks, pending demand, transaction size or computation, and the user's timing target. A fee that relays or confirms under one condition may be rejected, delayed, or unnecessarily high under another.
Fee recipients and disposition vary. A miner or validator may receive all or part, a protocol may burn a base fee, and a service or Layer-2 operator may charge separately. The quoted network fee should not be confused with an exchange withdrawal, spread, bridge, or payment-processor charge.
