A real place. A real reward.

Publish your actual shop location for the Stadtstack Ledger map. The server checks program ownership and records available rewards directly from Sepolia.

Create or restore a passkey account above before publishing a location.

Actual shop nameCity

LongitudeLatitude

Use your shop’s coordinates, in longitude then latitude order. Do not submit a private home address unless it is your public shop location.

Active Sepolia program

Rewards are derived from active, available on-chain offers, not a marketing claim. Create a redemption reward before publication, or publish again to refresh it.

I operate this actual shop, participate in this loyalty program, and consent to publicly publishing its name, city, coordinates, owner wallet and reward evidence. I understand that these are owner-published location claims, not an independent shop inspection.

One published location per program. Publishing again replaces that location. Review the registration message in the passkey prompt; no funds or tokens are transferred.

Point balances are encrypted. Program details and membership registration are public on Sepolia. The public map contains only signed registrations: ownership and available rewards are chain-checked at publication; names and locations remain the operator’s own claims.
