Seigniorage

Create your own currencies, design denominations, mint coins and print bills, then use them in player-driven trade systems.

Summary

Seigniorage gives servers the tools for all players to run custom economies built on player determined value.

Features

• Create custom currencies with unique name, 3-letter code, unit name, and 4×4 symbol.
• Design denomination sets as coins and bills with customizable appearance.
• Create issuance orders from the Currency Desk and process them into real money items.
• Use Wallets, Safes, and Netherite Safes to store and transport physical money.
• Handle player transactions through Voucher + Cash Register payment flows.
• Track economy data such as total issued and decommissioned value.

How To Create A Currency

1. Place and open a Currency Desk.
2. Create a new currency by filling:
   • Name
   • Code (3 letters, e.g. USD)
   • Unit name
   • 4×4 symbol

How To Create Coins And Bills

2. Fill name, value and personalize the palette, then click Create
3. Go to Currency Desk → Denominations and click Create Issuance Orders.

5. Make sure you have enough materials for each copy.
6. Process orders in a Coin Minter for coins and Bill Printer for bills,

How To Use Voucher Payments (Cash Register)

1. Create a Voucher Book and right-click to open the voucher writer.
2. Fill at least Amount and Currency Code, then confirm to create a Voucher.
3. Be sure to lock your Cash Register (merchant side).
4. Hold an unpaid voucher you issued and right-click the locked register to set payment mode.
5. The customer validates payment options (exact/lower/upper).
6. If exact exists: customer pays directly. Otherwise: customer offers lower/upper and merchant accepts.
