SweatPay
How it works

From wrist to wallet.

The whole system in one page: what we read from your device, how a day is scored, how the pool is split and what stops people cheating.

1

Connect

Sign in, add a Robinhood Chain wallet address, and authorise one or more devices through their official APIs. We ask for calories, heart rate and workouts, read-only. Revoke any time from the provider.

2

Sync

Data arrives every fifteen minutes, or on device upload for WHOOP and Garmin. Each fifteen-minute window is scored: active calories count only if a heart-rate reading exists in that window.

3

Rank

Your verified calories for the UTC day are summed and ranked against everyone else's. The leaderboard page updates as syncs land, so you can see whether it's worth one more run.

4

Lock

At 00:00 UTC the day closes. Late syncs are accepted for 60 minutes to allow for devices that were offline, then the board locks.

5

Review

Automated checks run on the top 50: plausibility, duplicate devices, impossible heart-rate patterns. Anything flagged is held for human review and the place is skipped, not paid to the next person.

6

Pay

One transaction per wallet on Robinhood Chain, usually inside the hour. Gas is paid by SweatPay. Every payout is public on the chain explorer and linked from your history.

Data

What we keep, and for how long.

Daily active-calorie totals, a flag per fifteen-minute window saying whether heart rate was present, and workout start and end times. Ninety days, then deleted. No raw heart-rate traces, no GPS, no sleep, nothing sold.
