Piglin Join WTO
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
A mod that allows Piglins to trade like villagers. This mod only needs to be installed on the server and will not affect the behavior of vanilla Piglins.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Piglin Join WTO Mod (PJWTO)
A mod that allows Piglins to trade like villagers. This mod only needs to be installed on the server and will not affect the behavior of vanilla Piglins.
Features
- Server-side only: Only needs to be installed on the server; no client installation required
- Vanilla compatibility: Does not affect vanilla Piglin behavior of picking up gold ingots for trading or player interactions with held gold ingots
- Intelligent trading system: Generates trades based on Piglin loot tables; rarer items require more gold ingots
- Custom trades: Supports adding custom trade items via configuration file
- Experience rewards: Trades grant experience points, with rarer items giving more experience
Usage
- Right-click adult Piglins with an empty hand: Opens the trading interface when right-clicking an adult Piglin with an empty hand
- Gold ingot trading: Use gold ingots to purchase items from Piglin loot tables
- Vanilla behavior preserved: Right-clicking Piglins while holding gold ingots still triggers vanilla trading logic
Trading Rules
Loot table-based trades
- Gold ingot requirements are calculated based on the item's weight in Piglin loot tables
- Items with lower weights require more gold ingots
- Trades are sorted by the number of gold ingots required, from least to most

- Weight 1 (rarest): Requires 15 gold ingots
- Books, iron boots, fire resistance potions, splash potions of fire resistance
- Weight 2 (rare): Requires 13 gold ingots
- Iron nuggets, ender pearls
- Weight 4 (uncommon): Requires 9 gold ingots
- String, nether quartz
- Weight 8 (common): Requires 1 gold ingot
- Obsidian, crying obsidian, fire charges, leather, soul sand, nether bricks, glowstone dust, gravel, blackstone
