Basic Cashbox details

Configure the following:

Total Amount: The total funds in the Cashbox. This amount is transferred immediately from the Cold Vault to the new Cashbox upon creating it. Additional amounts CANNOT be added to the Cashbox in the future.

Fee Lower Limit in Gwei and Fee Upper Limit in Gwei: This will determine the possible transaction gas prices when using the Cashbox. For example, if you choose a range between 10 and 20, you will be able to send transaction gas prices of 10, 11, 13, 15, 17 and 20. Choose a range which is wide enough to allow you to send transactions even if the fees change substantially in the future. (Note that the Max Fee is determined by the MPC Max Fee in the system preferences).

Fee for Creating the Cashbox in Gwei: This is the fee used to transfer the Total Amount to the Cashbox. The system pushes a notification to the mobile and desktop applications with a recommended fee as soon as you open the Cashbox creation window on the Cold Vault. This notification only works if the Cold Vault is plugged into the proxy via the yellow network cable.

Check the Advanced box in the upper right to access advanced Cashbox details.

Cashbox Advanced Details

Advanced Cashbox options include all the basic details, plus the following:

Total Amount: In advanced mode, this is the total amount of funds the Cashbox can send to the destinations over its lifetime. This is not necessarily the amount transferred to the Cashbox upon creation; funds can be added later.

Initially allocated Amount: The amount to transfer immediately from the Cold Vault to the new Cashbox upon creating it. This can be less then the total amount; funds can be added later. Importantly, while the Cashbox can receive ANY amount of funds over the course of its existence, it can only send up to the total amount configured earlier. Any funds in excess of that total amount are unable to be sent to the destinations.

Gas limit: The Gas limit to use in any transaction sending from the Cashbox to the outside. Configuring a value above 21,000 is only relevant if you plan to send funds to smart contracts.
