Maple BankTrade turns money into a system you can actually play with. Carry wallets, manage bank cards, trade items for currency, bind permissions to cards and machines, and push repetitive work into automated trading stations. The mod is built as a real banking and trading layer for NeoForge, with a public API so other content can plug into the same economy instead of inventing a second one.
Built-in content can be disabled, leaving the API and wallet systems available.
