Trade resources are a type of resource found on planets. They provide benefits to any player that has them. They can be traded to other empires. If you have one of these resources on a tile on one of your planets, you also have the option of destroying the resource, thus freeing up the hex tile for other buildings.
Bonus to Adjacent Improvements
Each trade resource on a planet provides an adjacency bonus to surrounding tiles.
Player Achievement Bonus
Each trade resource has a bonus associated with owning the resource. This is a global bonus that applies to your entire civ. The bonuses do indeed stack (despite the tooltip when looking at the resource saying "One Per Player") so owning 2 Precursor Nanites, for example, will give you a global +10% to your manufacturing on all of your colonies.
Note that if you trade a resource away to another civ and then lose your access to that resource, the civ that you traded the resource to continues to receive that resource until the number of turns expire, leaving you with a negative number of that resource. You do not receive any penalties from having a negative number of trade resources. There are several ways you could lose access to a trade resource:
- Destroy the trade resource on the colony screen of one of your planets.
- Give away or lose a planet to another civ.
- An agreement from another civ granting you the trade resource expires.
