The Nation Bank

Separate from your personal wallet, each nation has a shared bank. Open Nation Menu → Economy (Java), or use commands:

Command	What it does
/nation bank deposit <amount>	Move money from your balance into the bank. Any member with Bank Deposit (a default Member permission) can do this.
/nation bank withdraw <amount>	Move money from the bank to your balance. Requires Bank Withdraw.
/nation bank send <amount> <nation>	Send money to another nation's bank — foreign aid.

The nation bank is shown as Bank on /nation info, and it's exactly what war reparations are paid into and out of.

Taxes

A tax system is shown in the Economy menu for permission-holders but isn't built yet — it's planned for a future update.
