Starknet Fees

Starknet transaction fee are similar to legacy EVM fees.

A Starknet transaction pays transactions fees in gas.

New v3 transactions (which Fordefi supports) pays fees in STRK.

Each Starknet transaction is submitted with the following fields:

• Max Gas Amount: This provides a cap to the amount of gas units that will be used by transaction The maximum gas amount for a Starknet transaction is defined in wei units (1 STRK = 1,000,000,000,000,000,000 wei).
• Max Gas Price: The maximum gas price per unit.

Both maximum gas price and maximum gas amount are handled internally by Fordefi based on current network state and running simulations.
