Rewardrail
Compliant activity-linked rewards engine for stablecoin issuers and platforms
Rewardrail is an API that lets issuers and payment platforms run stablecoin reward programs structured around payment activity rather than balances, the distinction the CLARITY draft draws.

Test it before you build it
$1,200 · 5 weeks · 20 prospects
Prove two stablecoin platforms will pay $5,000 each, before CLARITY passes, for reward mechanics that survive the yield ban - $1,200 and 5 weeks.
Riskiest assumption · Product and compliance leads at US stablecoin platforms are blocked today from launching 2027 activity-linked reward programs by yield-ban uncertainty, and will pay for compliance-structured reward mechanics before the final CLARITY text passes rather than waiting for the vote.
1Focus group: who and where
Head of product or chief compliance officer at a US stablecoin issuer or payment platform of roughly 20-200 people with a live consumer or merchant payment flow, whose 2027 roadmap includes a cashback or rewards program that counsel has flagged or frozen over the GENIUS/CLARITY yield-ban language.
where to find 20 · Build the target list from the Blockchain Association and The Digital Chamber member directories and the Stablecoin Standard issuer membership; confirm which platforms are US-licensed via NMLS Consumer Access money transmitter records; reach them through warm introductions from crypto-focused counsel and fintech investors, and book on-site meetings at Money20/20 USA in Las Vegas in late October only if the test runs long.
2Sell first, build later
A design-partner pilot sold before any engine exists: a written reward-rule spec structuring your 2027 program as activity-linked mechanics, plus the audit export format proving every payout traces to a payment event, delivered within 45 days of the start date, with first access to the production engine.
the ask · $5,000 per pilot, invoiced up front; production engine pricing quoted at $40,000-60,000 per year and locked for design partners.
a real yes · A real yes is a paid $5,000 invoice or an issued purchase order with a start date on the calendar. Compliments, 'send us the spec to review', unpaid pilots and intros to counsel are not a yes.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Blocked-program interviews
$200 · 12 days
Write a 2-page brief, 'Activity-linked rewards under the CLARITY yield language', and use it as the hook to book 15 twenty-minute calls with product and compliance leads from the association directories and warm intros. On each call, ask what reward program is planned for 2027, whether legal has blocked or redesigned it over the yield ban, and who owns the decision.
keep going if · 8 of 15 confirm a 2027 reward program is stalled or redesigned because of yield-ban uncertainty and name the internal owner
2. Rule-spec teardown pitch
$400 · 10 days
For the 5 most blocked platforms, write a 3-page spec mapping their intended program to activity-linked mechanics - rewards computed from payment events, never balances - with the audit fields an examiner would ask for. Walk compliance and product through it together and ask for a paid design-partner pilot on the call.
keep going if · 3 of 5 platforms request the written pilot scope after the walkthrough
3. Paid design-partner close
$600 · 14 days
Send the scoped pilot to every platform that asked: a written reward-rule spec plus audit export format for their one program, delivered within 45 days, $5,000 invoiced up front, start date within 30 days. Have a fintech counsel spend one hour sanity-checking the pilot terms before sending.
keep going if · 2 platforms pay the $5,000 invoice or issue a purchase order with a dated start
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$5,000
per prospect, refundable
how · Paid design-partner pilot invoiced up front against a one-page pilot order form signed by the platform's product lead; this buyer routinely signs sub-$10k vendor pilots without full procurement, so an up-front invoice is credible where a checkout link is not. set up: Stripe Invoicing ↗
what it reserves · One of two design-partner slots for the 2027 program cycle, the reward-rule spec and audit export built against their specific program, and locked year-one pricing on the production engine.
refund · Refunded in full if the spec is not delivered within 45 days of the start date, or if the enacted CLARITY text bans activity-linked rewards outright before the pilot starts.
target · 2 paid pilots from 15 conversations within 35 days
before taking money · This sits next to GENIUS-regulated money, so do not hold funds, issue any rewards, or present the spec as legal advice before fintech counsel reviews the pilot terms.
Go: build it if
2 platforms pay the $5,000 pilot with a dated start and at least 8 of 15 interviews confirm a 2027 reward program stalled by yield-ban uncertainty.
Kill: stop if
Fewer than 5 of 15 interviews report a program blocked by the yield language, or 0 paid pilots and 0 signed POs after pitching all 20 prospects in 5 weeks.

outreach message
You are designing a 2027 rewards program while the Senate is still arguing over the CLARITY yield language, which means legal will not sign off on anything that smells like interest on balances. I have written a short spec for activity-linked reward mechanics - computed from payment events, never balances, with the audit trail to prove it - and I am pressure-testing it with 15 issuers and platforms this month. Can I get 20 minutes to walk you through it and hear where your program is stuck?
landing page
Activity-linked rewards that survive the yield ban, with audit proof $5,000 design-partner pilot: your program's reward rules specced as activity-linked mechanics plus the audit export format, delivered in 45 days Book a 20-minute scoping call - two pilot slots for the 2027 cycle
deposit terms
The $5,000 pilot fee reserves one of two design-partner slots and covers a written reward-rule spec and audit export format for your 2027 program, delivered within 45 days of your start date. It is fully refunded if we miss the 45-day delivery or if the enacted CLARITY text bans activity-linked rewards before your pilot starts. This is a product design engagement, not legal advice; your counsel reviews everything.

The concept in full
- What
- Rewardrail is an API that lets issuers and payment platforms run stablecoin reward programs structured around payment activity rather than balances, the distinction the CLARITY draft draws. It computes rewards from transaction events, blocks configurations that look like balance interest, and produces the audit trail showing every payout was activity-linked. Rule logic is versioned so programs adjust when the bill's text changes.
- Grounded in (2025-2026 signals)
- CLARITY cleared the Senate Banking Committee on May 14, 2026 and the motion to proceed was filed August 8, 2026 with stablecoin yield listed as an open point; the January 2026 draft's holding-interest ban versus activity-linked rewards allowance; stablecoin payment volume of about $390 billion in 2025
- What it rides
- CLARITY Act on the Senate floor: the January 2026 draft bans interest for merely holding a balance but allows activity-linked rewards, and this product operationalizes that line
- Why now
- A Senate floor vote is set up after the recess following the August 8, 2026 motion to proceed, and issuers designing 2027 programs need reward mechanics that survive whichever version of the yield language passes
- Wedge: first customer and entry point
- One mid-size stablecoin platform that wants a merchant-payment cashback program but cannot get comfort on the yield ban; ship the reward computation engine plus the audit export for that single program
- Closest real companies, as the generator saw them
- None tracked; Karsa and SpotPay hold consumer and business balances on stablecoin rails but nothing in the briefs builds reward compliance logic, and 'stablecoin' overall shows only 14 companies in the last 2 years
- Main risk
- The final CLARITY text bans activity-linked rewards too, or the bill stalls and programs launch without needing a compliance engine
