I will trade my artifacts for your artifacts, ku, or ctp. And I'll also pay ku, aid, or ctp for your artifacts. I listed how much ku and aid I'll trade for now. But with my mineral production, I accumulate it pretty quickly.

I have:
Halcyon Trap (Uses Left: 47)
Crimson Obelisk (up to 60)
Dark Pyramid (Uses Left: 106)
Omicron Mine Trap (Uses Left: 57)
Disarming Bomb (up to 34)
Calming Amplifier (Uses Left: 162)
Cloning Pods (up to 120)
Spy Probe - Defenses (up to 50)
Spy Probe - Weapons (up to 100)
Quantum Firewall Trap (Uses Left: 85)
Grav-Whip Trap (up to 9)
Subspace Seeker (up to 65)
Sentry Guards (up to 8)
Shield Sentries (up to 10)
Kurenite to give (up to 1600, but I can trade more as I accumulate it)
Aidonium to give (up to 150, but I can trade more as I accumulate it)
ctp (519)

I want:
Time Manipulators (as many as I can get)
Repair Nanodrones (about 10)
Containment Cages (about 10)
Grid Consoles (about 10)
Shield Amplifiers (about 20)
Shield Restorers (about 10)
Kurenite (as much as I can get)
ctp (nice to have, but I'd prefer artifacts or ku)

took care of most of what you asked for.
you got any space elevators, need about 18

Space elevators aren't tradable, I don't think

Vanderon is right. Space elevators are not sendable or shareable. You only get them from artifact pulls. I have been updating my list as I've traded and received artifacts.

yep your right.
just need a few more to make a demon world

I wish they were tradeable, though. I scrap so many of them

No, don't scrap them! They're required to make thermionic intensifiers (transformers a volcanic planet into a demon planet, 50 elevators each) and astrobiology wards (size: 1, pop: 500, pop bonus: 50%, 30 elevators each).

thanks for the warning Plagueis

If you have plenty of cargo space, I recommend that you don't scrap artifacts. Almost all artifacts are required for missions or CT lab blueprints. Also, if you keep them, they can be traded for other artifacts, ctp, em, minerals, etc.
