  • Gas fee The gas fee is the total, global amount paid for the transaction. It is calculated as: (base fee + priority fee) x units of gas used. Agent initially sets this amount based on the previous block’s history. However, users can edit this amount through custom settings (see below).
  • Total Total is the total cost for the transaction, include gas fee (BNB) and service fee (NLK).
