Smart Contracts
by Agent_Larry
Smart Contracts lets players write loans, debts, partnerships and company formation agreements as craftable documents that lock their terms once signed.
What it does
Each contract is made from a Blank Contract. Right-clicking it opens a menu where the player picks one of four frameworks: Loan, Debt, Company Formation or Partnership. Required fields are filled in a custom screen and the player clicks Sign, which converts the filled document into an official contract with a named Contract Owner. After signing, the stored data is locked, so the agreed text cannot be changed, and a signed contract can be copied to keep records.
The mod is built around multiplayer servers, where agreements between players need a record that nobody can edit afterwards. The contract types cover borrowed items with set repayment terms, IOU-style debts, shareholder businesses that declare starting capital, and partnerships that split equity and set project durations. The crafting ingredients are simple vanilla items, so the feature is usable in survival worlds without extra progression mods. The mod is published for Forge only, for Minecraft 1.20.1, and it has to be installed on both the client and the server.
Key features

Loan, Debt, Company Formation and Partnership contracts each have a dedicated form and layout.
Locked contract data
Once a contract is signed, its stored NBT data is locked so the terms cannot be altered later.
Custom contract screens
Required input fields appear in a custom interface, with a clear Sign button to finish the document.
Crafted from vanilla items
Blank contracts are made from simple vanilla-friendly ingredients, so no special resources are needed.
Contract copying
