A commodity-anchored unit of account. 1 Ð is defined by a fixed basket of 11 physical goods — the things people actually need to survive.
Every Duro is anchored to a specific physical quantity of 20 real commodities. The basket is constitutional — it does not change without a supermajority vote of the Oracle Council, and only on Earth Day (22 April). It does not drift with monetary policy, interest rates, or market sentiment.
Prices are fetched every 15 minutes from commodity exchanges and international indices. Sources are ordered globally — Euronext, LME, and FAO lead where they exist; US exchanges are included as secondary averaging sources. The basket value is the sum of 20 equal-weight components, each contributing approximately SDR 0.048.

Alpha quantities computed 17 March 2026 from spot prices. Final constitutional quantities will be set at the first Earth Day calibration (22 April 2026) using the 365-day rolling average expressed in IMF SDR.
Duro does not target a fixed USD price. The basket value floats with real commodity prices. That is the point — Duro tracks the cost of physical reality, not the value of any fiat currency.
Think of it as a commodity index in coin form. Duro measures the cost of physical reality — the things people actually need to survive — not the value of any fiat currency. When food and energy get more expensive, 1 Ð costs more in USD. When they get cheaper, it costs less.
Beginning 22 April 2026 (Earth Day), the Oracle will publish 24-hour, 7-day, and 30-day directional price forecasts for every commodity in the basket and the full reference universe. Free. No account required.
Forecasts are generated from commodity fundamentals, seasonal patterns, macroeconomic signals, and supply chain data — not from speculative sentiment or social media volume.
All prices are available via the public API at no cost.
