In one line

The business pays a small fixed cost to add a chance to win to a payment. Fade’s vault pays the reward. The vault pays it to the account the business names in the ticket, and the business credits its customer. The customer pays nothing extra and never more than the normal price.
Two separate amounts. The business pays the ticket price, a fixed cost on every payment: 1.04 USDC per 100 USDC order, whatever happens. Fade's vault pays the reward in full to the business when a ticket wins: 100.00 USDC, about 1 order in 100, which the business credits to its customer.Two separate amounts.

The example below: a merchant offers 1 order in 100 on us, on a 100 USDC order.

One margin, set upfront

Every payout table declares a margin: what a ticket keeps of its price on average. It is checked on-chain before any money moves, and split the moment the ticket opens:
How a ticket price splits, with a 4 % margin and a 2 % app share: 96 % comes back to customers as rewards on average; the margin splits into a 1 % protocol share, a vault margin of at least 1 %, and the app share, 0 to 5 % at the app's choice.How a ticket price splits, with a 4 % margin and a 2 % app share: 96 % comes back to customers as rewards on average; the margin splits into a 1 % protocol share, a vault margin of at least 1 %, and the app share, 0 to 5 % at the app's choice.

The worked example below: a 4 % margin with a 2 % app share.

So the smallest margin a payout table can declare is 2 %, plus the app share. The rest of the ticket price, on average, comes back to customers as rewards.

A worked example

A merchant offers “1 order in 100 is on us” on a 100 USDC order, with an app share of 2 %: The merchant’s cost is 1.04 USDC per order whatever happens. With no app share the same offer costs about 1.02 USDC. The arithmetic of each use case is on its page: Card payments, Swaps, Merchants and checkouts.

SOL: the integrator’s own payer

Each ticket also needs a little SOL, for its account’s rent, its oracle draw and the keepers who move it forward. The payer the integrator names advances it, and most of it comes back when the ticket closes. Fade never pays SOL for an external integrator. The public keeper is paid by the crank fee each ticket prepays, like any other keeper. The amounts are on Margin and shares.
