Ecosystemlogic is a Bedrock survival addon that makes emeralds your world’s real currency—not just villager bait.

Pick up emeralds and they automatically convert into a personal balance you can spend at the market, send to other players, or withdraw back as physical emeralds anytime. An optional balance HUD in the top-right keeps your wallet visible while you play, and you can turn it off in Settings.

Market Terminal
Every player receives a locked Market Terminal on the rightmost hotbar slot. Use it to open the in-game market with live buy/sell quotes, category filters, search, and sorting—no chat commands required.

Dynamic NPC Market
300+ catalog items with prices driven by supply and demand. Buy when stock is low, sell when it’s high—but watch out: background market activity, demand shocks, supply booms, and market panic events can move prices fast. Items unlock for trading the first time you obtain them, so progression feels natural in survival.

Player Marketplace
List items from your inventory, browse other players’ offers, buy at asking price, or negotiate. Sellers can require approval, allow instant buyouts, keep listings while offline, and receive notifications for purchase requests and counter-offers. Enchantments, durability, lore, and other metadata are preserved through escrow.

For items outside the NPC catalog, recent peer trade history helps you price listings—last 5 trades, with an average range after 3+ sales.

Fair-play safeguards
Opposite-trade cooldowns and a progressive trade tax reduce spam arbitrage without killing legitimate trading.
