Closed-loop token payments for businesses

Pre-cleared payments, proven on a ledger.

Customers buy tokens by card and spend them at your checkout, and you are paid out in money. Every step posts to a double-entry ledger, and a checkpoint of that ledger is published.

What sits under every payment

How we show each of these

Three ways in

How the closed loop works

  1. The customer buys tokens

    By card, on a payment page we host.

  2. The tokens are pre-cleared

    The payment is checked before the tokens reach the customer, not after.

  3. They spend them at your checkout

    Only at approved businesses. Tokens cannot be withdrawn to cash or sent to someone else.

  4. You are paid in money

    Your balance matches the ledger to the cent, and it is paid out to your bank.

Every penny has a line in the ledger, and anyone can check the checkpoint.

Each checkpoint publishes a commitment to the ledger's hash chain, so a later change to any line would show.

Not a card gateway with a token bolted on.
