creeprchain
by f1nrod
With creeprchain, an ATM block turns items a player hands over into ERC-20-style tokens recorded on an Ethereum-compatible blockchain, with balances viewable in MetaMask.
What it does
Placing an ATM block gives players a point where items are exchanged for tokens. A right-click while holding a diamond triggers the conversion, and the resulting tokens are recorded on a blockchain. The chain runs as a separate local Ethereum node, started from a terminal on a dedicated Linux machine. After the server restarts with the mod configured, tokens show up in MetaMask for the connected wallet.
Setting up the chain follows a short sequence: install Fabric Loader and Fabric API for Minecraft 1.20.1, place the mod, start the local node on 0.0.0.0:8545 with chain ID 31337, and keep that terminal running. Then a second session on the same host runs the remaining commands from the blockchain folder. A server owner restarts the Minecraft server afterward and checks the log.
If the private key setting is left empty and the contract address is set to zero, creeprchain keeps its records only in a SQLite database. The mod requires Fabric API and is published only for Fabric. It is released under All rights reserved, so it is not open source, and its source code and issue tracker are publicly linked.
Key features
Item deposits at an ATM block
A placed ATM block accepts items from players and returns ERC-20-style tokens in exchange.
Ethereum-compatible chain
Token records follow an Ethereum-compatible blockchain that the server runs as a local node.
MetaMask token view
Balances appear in MetaMask, so players can see their tokens in a standard wallet.
Local-ledger mode
With an empty private key and a zero contract address, transactions stay in a local SQLite store.

Server economies
Server owners can run an item-to-token economy on a Fabric server, with the chain kept on a separate machine.
Testing token flows
Local-ledger mode lets a developer exercise deposits without a live contract address.
Who it’s for: Server owners who want an item-to-token economy on Fabric and are comfortable running a local Ethereum node on a separate Linux machine.
