The case for CU5N

Cost-efficient

Own, trade and sell 5N copper exposure without the headache of physical handling, storage, insurance and certification costs.

Decentralized

Held in a trust and governed by a foundation.

Certified

ISE assayed for purity. ISE valuation.

Verifiable

Each token is attributed to a specific lot held in storage.

Redeemable

The only ISE-certified 5N ultra-pure copper that is redeemable for physical delivery.

Ownership lookup

CU5N holders can look up their specific lot allocation by inputting their Ethereum address. Every token is backed by physical copper held in Cyprium's private storage facility in Embrach, Switzerland.

EVERY CU5N TOKEN = ONE GRAM OF ALLOCATED 5N COPPER POWDER

Our copper

The Cyprium Trust holds 500 kg of sub-micron, ultra-pure and ultrafine 5N copper — among the highest grades of copper, typically reserved for research, sciences and electronics. Copper is the material constraint on nearly everything being built right now: AI datacenter thermal systems, fusion magnets, quantum computing hardware, rocket engine chambers.

IN NOVEMBER 2025 THE USGS ADDED COPPER TO THE U.S. CRITICAL MINERALS LIST FOR THE FIRST TIME.

Quantum computing

Used as a conduit for heat where thermal conductivity in the millikelvin requires the highest grade copper.

Rocket engine — Merlin 1D test fire

Rocket science

Used in the lining of SpaceX's Merlin combustion chambers where high thermal conductivity ensures component survival.

Particle accelerator — collider detector

Particle accelerators

Used as RF conductor in resonating copper cavities to deliver consistent high energy beams.

Cold spray deposition — aerospace repair

Cold spray deposition

Used in aerospace cold welding for component repair and rebuild.

AI GPU interconnects

Instantaneous data transmission for Nvidia's NVL72 GPU clusters where high purity makes the difference between errored or clean data.

Fusion reactor — superconducting magnets

Fusion reactors

Used for superconductor heat and magnetic energy dissipation.

How it's made

Ultra-pure 5N copper is meticulously refined, packaged and stored using up to 30 process operations plus 8 analytics methods, taking approximately 6 months to produce.
