Speeds merchant cargo runs and Exchange purchases by 10% per level; reduces market fees by 5% per level, up to 50%.
Improve exchange delivery speed and reduce fees. It pays off through repeated trade activity; a self-sufficient outpost may benefit more from another immediate production upgrade.
To establish this building, you need 🏛️ Main Building level 1; 🏪 Trade Hub level 10; 💱 Exchange Nexus level 10.
For later upgrades, the Main Building must also reach the target level. The level table shows the resource and time investment before bonuses.
The building definition has no direct structural or active power upkeep. Check the powered extractors, crafting and recruitment that support its use when planning the wider grid.
📸 Screenshot wanted: the Global Commerce Exchange detail panel in a colony (level, upgrade cost and its main controls visible). If the building has a Race name, one shot per Race is ideal.
