COPPER ACADEMY

Copper (Cu) is one of the oldest metals known to humanity. It conducts electricity better than almost any other element, which is why it's inside every wire, motor, and circuit board on the planet.

It comes from mines in Chile, Peru, the Congo, and dozens of other countries. Global demand runs around 25 million tons per year and is rising fast — electric vehicles use 3-4x more copper than gas cars.

Copper is priced per pound in the US market. As of mid-2026, it trades around $4-7 per pound depending on market conditions.

COMEX is the primary exchange for trading metals futures in the United States. It's part of the CME Group — the world's largest derivatives marketplace.

Copper futures trade Monday through Friday. The exchange is closed on US federal holidays. Some holidays have early closes at 12:00 PM CT — before our 3:00 PM SPOT time — so those days are non-trading days.

When you hear "the copper price," it usually refers to the COMEX front-month futures contract.

Every trading day, you make one prediction: what will the copper price be at 3:00 PM Central Time — market close? We call this "calling the spot."

THE WINDOW — Lock your guess before 12:00 PM CT. Pick a price, hold the button to confirm. No changes after lock.

THE SPOT — At 3:00 PM CT, the day settles using the Class A oracle on Base. Every settlement references its blockchain transaction hash.

THE WINNER — Closest guess wins. Ties broken by lock time (recorded to the millisecond).

CHECK IN is the key on the TI-41 keypad, below GRAPH. Pressing it once a day is the only thing that builds your check-in streak — you do not have to call the spot, and calling the spot does not count for you. It is deliberately the easiest thing on the device to do.

THE BUILD — Each check-in welds another section onto the RWACU rig in the panel beside the calculator. Seven consecutive check-ins finish the machine and earn a $RWACu reward, then the next build starts.

72 HOURS — Your streak dies if 72 hours pass without a check-in. That is a real clock, not a count of trading days: you can miss two whole days, weekends included, and still be saved on the third.

Rewards are paid in $RWACu on Base, so link a wallet if you want to collect. Guests can still build streaks — they just cannot be paid.

Separate from the check-in streak above, your play streak counts consecutive trading days where you locked a guess.

GRACE PERIOD — Your streak survives up to 2 consecutive missed trading days. Miss a third and your streak dies — that's the quench.

Weekends, COMEX holidays, and void days don't count against you.

The Class A oracle is an on-chain copper price feed on Base (Ethereum L2). Updates every 15 minutes during trading hours.

Every settlement records the oracle transaction hash. Anyone can verify on Basescan. If the oracle goes down at SPOT time, we wait up to 2 hours. If still unavailable, the day voids. We never use fallback sources.
