Pay-or-Play Parity
Every RSNC spend in Resonance also offers two other rails at a fixed parity — USDSC and Card:
1 USDSC = 1,000 RSNC
Pay or play. Payers buy time. Players grind RSNC. Both feed brand demand for the same items. For the full "which button do I press" decision, see Spending RSNC.
The core rule
- Anywhere you'd spend RSNC (perks, Kitchen items, forge fees, mulch fees, transmute fees), there are USDSC and Card buttons beside the RSNC button. All three are live.
- USDSC and Card pricing is flat — it's the parity peg, and it doesn't move. Card runs through Stripe at the same parity as USDSC.
- RSNC pricing gets your Tune-In discount (see below). USDSC and Card don't.
So a Tune-In L20 user (8% discount) pays either 920 RSNC or 1 USDSC (or $1 on Card) for a 1,000-RSNC item. A modest pull toward RSNC for engaged users; parity for everyone else.
Tune-In discount on the RSNC side
Tune-In's role in spending is to discount RSNC prices on a diminishing curve, capped at 20%:
| Tune-In level | RSNC discount |
|---|---|
| L1 | 0% |
| L5 | 2% |
| L10 | 5% |
| L20 | 8% |
| L50 | 13% |
| L90 (Resonate) | 20% (capped) |
The discount only ever applies to RSNC spends. The USDSC and Card price for the same item is identical at every Tune-In level. This protects the parity peg — USDSC and Card always represent the same amount of work regardless of who's paying.
Where parity applies
| Surface | RSNC side | USDSC / Card side | Status |
|---|---|---|---|
| Perk claims | Burn RSNC (discounted) | buyWithStablecoin on PointsSale, or Card at parity | Live |
| Kitchen producers / equipment | Burn RSNC | buyWithStablecoin at parity | Live |
| Kitchen recipe inputs | Use ingredients (free) or buy with RSNC | Buy with USDSC at parity | Live |
| Producer slot 4 + slot 5 | 5,000 / 15,000 RSNC | $5 / $15 USDSC | Live |
| Cooking slot temporary expansion | 5K / 10K / 15K RSNC for 7-day slot | $5 / $10 / $15 USDSC | Live |
| Forge fee (first mint) | 500 RSNC (350 for Signal subscribers) | Equivalent USDSC | Live |
| Forge extra mints (#2–#6) | n/a — already USDSC-native | $1 / $3 / $6 / $12 / $24 USDSC | Live |
| Mulch fee | 100 RSNC per dissolve | 1 USDSC per dissolve | Live |
| Transmute fee | 500 (Std→Rare) / 1,000 (Rare→Mythic) RSNC | Equivalent USDSC | Live |
The RSNC, USDSC, and Card buttons on perk cards all work today — being short on RSNC no longer blocks a claim, since the USDSC and Card buttons stay live. See Spending RSNC for how to choose between them.
What buyWithStablecoin does on-chain
The on-chain contract method that powers the USDSC path is PointsSale.buyWithStablecoin(token, amount, recipient). Its selector is 0x382be1c5. It already powers:
- Forge extra mints (#2–#6 in USDSC)
- Signal subscription purchases
When you pay with USDSC, the contract also mints the equivalent RSNC to your wallet as a side effect (it's a "buy RSNC with stablecoin" contract). For Pay-or-Play, that's intended — you get the item AND the equivalent RSNC, which you could immediately re-burn if you wanted. Net economic outcome matches a 1:1 USDSC swap.
Rounding
USDSC has 6 decimals; RSNC has 0 decimals. Parity rounds up on the USDSC side so the platform never loses sub-unit RSNC to fractional USDSC:
| RSNC item | USDSC paid (parity, rounded up) |
|---|---|
| 500 RSNC | 1 USDSC |
| 1,000 RSNC | 1 USDSC |
| 1,500 RSNC | 2 USDSC |
| 5,000 RSNC | 5 USDSC |
Why it's set up this way
Two cohorts use Resonance differently:
- Payers show up with money and time pressure. They want to skip the grind and unlock the item.
- Players show up with time and want to grind their way in.
Both pay the same brand demand, both move the same supply curve. The grinder creates the RSNC supply; the payer absorbs items at a parity-stable price. Brand revenue from USDSC purchases gets split 70/30 (brand / platform) — see the Resonance pivot spec for the full economics.
The Tune-In discount preserves the original Tune-In value prop for engaged users without breaking the peg for everyone else.
