All-in pricing, fees, and payouts

The game fee is inside all-in

Contract-exact raw-unit accounting

A = user-selected all-in limit
S = principal (shown as B in contract-facing state diagrams)
S = floor(A × 10,000 / 10,350)
Fee = ceil(S × 350 / 10,000)
settlement = S + Fee ≤ A
Manual prize = 2 × S
Mystery prize = floor(S × 25,000 / 10,000)

A is what the user agrees to spend in USDG terms. S—also labeled B in the contract-facing state diagrams—is principal, and Fee is the refundable 3.5% fee calculated from principal. The interface must not add another 3.5% after the user selects A.

Exact examples

All-in A	Principal S	Fee	Manual 2x	Mystery 2.5x
1.000000	0.966183	0.033817	1.932366	2.415457
10.000000	9.661835	0.338165	19.323670	24.154587
50.000000	48.309178	1.690822	96.618356	120.772945
100.000000	96.618357	3.381643	193.236714	241.545892
200.000000	193.236714	6.763285	386.473428	483.091785

Integer rounding may leave one smallest USDG unit below A; it can never push settlement above the signed limit. For example, the 200 USDG row settles at 199.999999 USDG, not 200.000000.

When the fee becomes revenue

Game state	Fee state	Refund / VOID	Required next action
Coin · AwaitingRandomness	`F` remains pending refundable Fee Escrow	Only while still AwaitingRandomness and either frozen time or block timeout is reached: `refundExpired` returns `B + F`	Wait for VRF, or call the qualifying timeout path
Parity · AwaitingReport	`F` remains pending refundable Fee Escrow	Only after the inclusive report deadline, while still AwaitingReport: `voidExpired` returns `B + F`	Submit the report through the deadline, or VOID one second later
Parity Mystery · AwaitingRandomness / AwaitingReport	`F` remains pending refundable Fee Escrow	Only after the report deadline, while still in either awaiting state: `voidExpired` returns `B + F`	Complete selection/report, or call the qualifying VOID path
Coin · RandomReady / Parity · ReportReady	`F` is still held by the Game but the refund/VOID branch is closed	No refund or VOID: the outcome/report is frozen and these functions reject the state	Anyone must call `settle`; a ready result cannot be converted back into a timeout
Settled	`F` moves to settled Fee Escrow	No refund or VOID	Only now may anyone call `flushFee` exactly once
Refunded / Voided	`F` was returned with `B`	`B + F` has already left the Game	`flushFee` is permanently unavailable for this Bet/Ticket

The current rulesVersion gives Game Fee Treasury no withdraw, spend, allocate, sweep, or Reserve refill path.
Protocol Hook fees, V4 LP fees, price impact, slippage, and gas are separate market costs and must be shown separately when applicable.

Timeout refund and Bond compensation are separate

Frozen ticket accounting

refundRaw = B + F
additionalReserveRaw = prizeNotionalRaw - B
user timeout/VOID receipts = refundRaw from Game + additionalReserveRaw from responsible Bond

A qualifying Coin timeout or Parity VOID returns the refundable principal and fee from Game escrow. In the same terminal transaction, the responsible VRF Provider or Reporter Bond is slashed for exactly the Ticket’s frozen additionalReserveRaw. Compensation is not taken from B, is not a fee refund, and must be shown as a separate receipt/event field.

Manual: Prize is 2B, so additionalReserveRaw = B.
Mystery: Prize is floor(2.5B), so additionalReserveRaw = prizeNotionalRaw - B.
No double terminal: A refunded/voided Ticket cannot later settle; late randomness or reports cannot recreate the exposure.
