What the user sees

Your cashback Take 2.00 USDC, or a 1 in 10 chance at 19.30 USDC.
Or: “Put 10 % of your staking rewards on a multiplier.” The user picks. When they take the shot, the payout is guaranteed by the pool, not by a marketing budget that might run out.

​
The arithmetic

A 2.00 USDC cashback becomes a stake on a two-outcome paytable at a 3.5 % declared edge: Σ p·m = 100 000 000 × 96 500 = 9 650 × 1e9: exactly a 3.5 % edge. The liability is 17.30 USDC, which an idle pool carries from about 1 200 USDC of assets. A paytable does not have to be all or nothing. Three tiers keep a small floor for most users and a larger prize for a few: Every tier that pays less than 1× is what makes room for the larger prize: if every outcome paid at least the stake back, the expected return would exceed 1 and the program would refuse the paytable.

Who funds the stake

​
How it is wired

The rewards program is the app. If the user signs, stakeOwner is the user and stakeSource is the user’s USDC account holding the reward. If the program holds the rewards and stakes on the user’s behalf, it signs as stakeOwner and names the user’s account as beneficiary.
Prize-linked payouts are subject to local gaming and promotion law. Whether a reward with upside is a promotion or a wager depends on who funds the stake and on the market.
