Platform fee

Pzero charges a flat 10% of gross USDC on every cleared trade. Suppliers keep 90%. It is a transparent fee, not an opaque bid-ask spread.

The formulas

gross_usdc        = diem_cleared × clearing_price_cents / 100
fee_usdc          = gross_usdc × 10%
net_supplier_usdc = gross_usdc − fee_usdc

The fee is fixed at 1000 basis points. It is not tiered, and it does not scale with price.

Worked example

A $1 DIEM face clears at 40¢:

Line	Amount
Gross	$0.40
Fee (10%)	$0.04
Supplier net	$0.36

Who bears it

Marketed as "10% platform fee on cleared trades." Operationally, the supplier receives the net, so the fee is economically borne on the supply side, while buyers consume against the full gross value of their deposit.

Self-clear

If the same wallet is both the buyer and the supplier on a clear, the buyer debit and supplier credit net out, leaving a net change of just the fee.
