The 30–80¢ corridor
Every cleared trade on Pzero falls between 30¢ and 80¢ per $1 of DIEM face value. This band is the heart of the protocol.
- Floor: $0.30. Blocks penny-stock micro-clears that would drown the protocol in settlement events without meaningful revenue.
- Cap: $0.80. Enforces the minimum 20% off promise: if the most a buyer ever pays is 80¢ on the dollar, every cleared trade is at least 20% below the $1 face value.
The cap is why the headline holds mechanically, not as a slogan: Frontier models. Minimum 20% off.
How the clearing price is set
Suppliers post a fixed price within the corridor. Buyers set a max price, the most they are willing to pay per $1 of face value, which is the same as the minimum discount they require.
- The router selects the cheapest eligible offer whose posted price is at or below the buyer's max.
- The clearing price is the seller's posted ask: never the buyer's max, never a midpoint.
- Any surplus below the buyer's ceiling is reported as savings; it is never charged.
Worked example
A $1 DIEM face clears at a 40¢ posted ask:
| Line | Amount |
|---|---|
| Gross | $0.40 |
| Platform fee (10%) | $0.04 |
| Supplier net | $0.36 |
The buyer pays 40¢ for $1 of inference value, a 60% discount on that clear, well inside the corridor.
