Tradery

Player shops in a block, a currency you can see on screen, and coin ore as the source of money.
The spiritual successor to Vending Block - for Fabric and NeoForge, with a public Economy API.

About

Remember Vending Block? Put a block down, stock it, set a price - and people buy from you while you're off mining. Tradery brings that back for modern Minecraft and builds a whole small economy around it:

• Vending blocks that sell for items (the classic way) or for money - or buy goods from players.
• A virtual currency with your balance always in the corner of the screen.
• Coin ore in the world, so money comes from playing, not from an admin's command.
• Trade without opening a window: sneak + right-click to buy, hold to keep buying.
• Built for servers: permissions, configs, logs, crash-safe saves - and an Economy API for other mods.

Vending Blocks

A red-and-brass machine with a glass case on top - the goods float inside so everyone can see what's for sale.

• One block, one offer: "4 bread for 2.50" or "1 diamond sword for 2 diamonds". Up to 64 items per trade, 27 slots of stock.
• Money or items: money goes straight to the owner's balance (minus a configurable fee); items land in 9 revenue slots.
• Buyback: flip one switch and the block buys the goods from players with the owner's money - a market for your miners.
• Sells while you're offline. Online, you get "Sold 16 × Bread for 40.00 ₮ (Steve)"; when you join, a summary of what sold while you were away.
• Facades: any full block as the base - oak, spruce, stone bricks, whatever fits your shop.
• Showcase animations: static, spin, bob, spin & bob, or hidden.
• Display block: a glass case that shows an item and sells nothing - for trophies and shop windows.
• Admin vendors with the vendor key: infinite stock, payment burned as a money sink, no fee, owned by the server.
• Safe by design: only the owner can break it (explosions, pistons and hoppers can't touch it), the buyer screen has no item slots to exploit, and every sale checks stock, money and room before anything moves. Every case is covered by automated tests.

Buyer	Owner

Quick Trade & Look-at Hint

Look at a vending block and a small card shows who sells what and for how much - no window, no guessing.

• The block in your hand is never placed by accident, and the machine is never mined.
• The action bar adds the whole streak up: "Bought 20 × Bread for 12.50".
• Sold out or not set up? The card says so in red before you click.

Balance HUD

Your balance in any corner, with a coin icon, a rolling counter and +120 / -40 popups.

• Any corner and offset, scale 0.5–2, full (1 250.00) or short (1.2K) format.
• Hidden with F1, a key (unbound by default) or /tradery hud.
• Moves above the hotbar on small screens; tested at GUI scale 1–4.

Where Money Comes From

• Coin ore in three tiers - copper, silver, gold - in stone and deepslate. Mining it puts the coins' value straight on your balance; machines and explosions drop coin items instead.
• No doubling: Fortune doesn't multiply money, coin ore isn't a c:ores ore and has no furnace recipe, so crushers and ore processors can't double it.
• Coins are cash: right-click to deposit, /tradery withdraw to pay out, trade them in item-priced vending blocks.
• Rewards for killing mobs (on by default), and optionally for mining, crafting, fishing and advancements. Spawner mobs pay nothing; diminishing returns and a daily cap keep farms honest.
• Money sinks: the vending fee, the /pay tax, burning admin vendors. /eco stats shows money created and destroyed per day.
• Vein count, size and height are data-pack JSON - tune them like vanilla ores.

Commands

Amounts are typed in normal units (/pay Steve 12.50). Permissions work with LuckPerms or any permission mod.

For Servers

• config/tradery/server.json5 - currency (name, symbol, decimals, separator), starting balance, balance ceiling, /pay tax, vending fee and per-player limit, item and facade blacklists, coin ore on/off, direct-to-balance, coin values, daily cap, inflation damping, log retention.
• rewards.json5 - rewards per mob / block / item / advancement (ids, #tags or *), spawner and fake-player rules, daily cap, diminishing returns.
• client.json5 - each player's HUD, hint and notification settings.
• Broken values fall back to defaults and are reported in the log; /tradery reload applies changes.
• Every transaction is logged to <world>/tradery/logs/YYYY-MM-DD.log (JSON lines).
• Crash-safe: when Minecraft writes a vending block's chunk, the money and the traders' inventories are written in the same tick. After a crash the stock, the money and the items always match - checked with a real kill -9.
• Hoppers and pipes can't touch vending blocks - nothing to dupe through automation.

For Developers

dev.eliasnvx:tradery-api:1.0.0+26.3 - accounts, atomic transactions and events, one API for Fabric and NeoForge.

TraderyEconomy eco = TraderyEconomy.get();               // server thread only
Account account = eco.account(player.getUUID());
TransactionResult result = eco.withdraw(account, 500,    // 5.00 with 2 decimals
    Reason.of(Identifier.fromNamespaceAndPath("mymod", "teleport_fee")));

// 5% tax on every vending sale inside a region
VendingPurchaseEvent.Pre.EVENT.register(e -> {
    if (Regions.at(e.pos()).is("market")) e.setPrice(e.price() * 105 / 100);
});

Guide: docs/api/README.md. On Fabric, Tradery is also a Common Economy API provider, so mods that use it work with Tradery balances out of the box.

Compatibility

All optional. EMI and WTHIT support will follow when they update to 26.3.

Installation

1. Install the loader for Minecraft 26.3 (and Fabric API on Fabric).
2. Download Tradery for your loader.
3. Drop the .jar into mods - on both the client and the server.

FAQ

Does it work on a server without the mod on clients? No - the blocks, the HUD and the screens need Tradery on both sides.

Can hoppers fill or empty a vending block? No, on purpose: automation is the classic way to dupe shops.

Can I use another currency name or symbol? Yes - name, symbol, decimals and the thousands separator are in server.json5. The HUD and screens show a coin icon instead of the symbol.

Will it come to 1.21.1 / 1.20.1? A 1.21.1 backport is planned for 1.1.
