PolyWallet (polymer)
by jthkhaose
PolyWallet gives a Fabric server a persistent, SQLite-backed economy, with wallet accounts, several currencies and a casino built on the same money system.
What it does
Wallet accounts are stored between sessions, and each account can hold balances in multiple currencies. Players send money to one another, and every transfer is recorded in a transaction history. Admins get audit tools that can roll back a transaction. A primary currency can carry a custom symbol and a scale used when amounts are displayed, and a first-run setup along with a one-command quickstart initializes the economy on a fresh server.
The same money system is used by shops, merchants and exchanges, and by the casino games, which share one reward and tender system. Physical blackjack, Texas Hold'em and roulette run on the server with Polymer, so vanilla clients can join without installing the mod. Autonomous villager-like gamblers also appear as patrons. The mod is published only for Fabric, for Minecraft 1.21.11, and it is server-side only, so players need nothing installed. It is released under All rights reserved and is not open source.
Key features
