Ten years of copper data, written in public.
$RWACu is a 10-year public experiment: an ERC-20 token recorded on Base, documented alongside 2,000 pounds of industrial copper held in four steel drums at a working copper manufacturer established in 1991. Every price update, burn, and reserve change is published here. Nothing is promised. Everything is recorded.
Traditional RWAs sell custody.
This one publishes a dataset.
Volume through utility
No emissions. No incentives. Every interaction with an mj41 app that consumes RWACu is real on-chain activity from real use. The apps are the distribution strategy. Use is the only mechanic.
The data is the moat
Class B scrap and Class C industrial oracles publish pricing sourced from an operating copper manufacturer. No gold-token RWA publishes industrial-grade pricing. The first recycler subscription matters more than any pool mechanic.
Independently verifiable
Supply, burns, reserve contents, and project wallets are published on this page with direct links to the chain. Don't trust the copy. Check the contract.
Three classes of copper.
Priced on a public blockchain.
Each oracle has a free /status endpoint and an API. Agents reach the same feeds over MCP. Class A is free. Classes B and C are the subscription product.
Class A — COMEX Spot
Exchange spot copper, automated updates. The reference price everyone already has — published on-chain anyway, for free, as the baseline.
API · classa.mj41.me0x02a0FeE571E63e9a81AE944469deA7207ac56D8f
Class B — Scrap Copper
Scrap-grade pricing, updated manually every week from the floor of a real operation. The number recyclers actually buy and sell against.
API · classb.mj41.me0xB5e39A30fa4fB583DF56B4CE8e9F9AD683280116
Class C — Industrial Copper
Industrial-grade pricing covering C110, C182 / RWMA Class 2, and C180 / RWMA Class 3 — the alloys that move through Tier 1 automotive supply chains. The first industrial-grade copper oracle on a public blockchain.

The toolkit runs on RWACu.
One command gives any terminal — or any AI agent — access to the mj41 suite of copper-data tools over MCP. Calls are priced in RWACu and settled as prepaid call packs, because the rate is too small to settle one call at a time on-chain.

Copper Oracle MCP
Class A, B, and C feeds for agents. Status endpoints free; priced feeds keyed with x-api-key.
Blockchain Activity Monitor
Live as a Farcaster mini app and reachable on the open web. Streamlined chain lookups for agents — API and MCP access are in development.
The 10-Year Data Plan
A decade of copper pricing, supply, burn, and reserve records, accumulating in public from day one. Subscription access to the full dataset as it builds.
Use is the only mechanic.
IdeaMint
Pay $0.41 to permanently timestamp an idea on-chain. Proof you had it first, recorded forever.

One number that only goes down.
Supply started at 100 billion. It does not go up. Burns from app use and public burn events are permanent and visible on-chain.
