About this Mod

IOU

Friendly Debt Management for Minecraft! 💰

Allows you to drop IOUs for items to say "hey, here's a paper reminding you that I'll pay you back!"

First, take some cool items from your pal.
Then press Ctrl + I while holding an item (stack) to generate an IOU (stack). It will get tossed in front of you, just like you dropped it. Your pal can pick it up!
Once you return or repay the items, your pal can delete the IOU(s) by right clicking the IOU with the owed items in their inventory (holding the returned item(s) in your cursor and right clicking the IOU(s) like a bundle)
You can make a strict IOU (NBT must exactly match) by instead pressing Ctrl + Shift + I

Frequently Asked Questions

IOU server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is IOU compatible with fabric?

IOU officially supports fabric for Minecraft 1.20.1, 1.19.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with IOU – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if IOU consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
