POS demo

One sale, start to settled.

A simulated walkthrough of what happens when a merchant terminal on the Mainstreet gateway takes a Solana payment: the terminal pairs, the customer pays, and the sale settles on-chain. Nothing here moves real funds — the timings are real.

  1. 01Waiting

    Pair with the gateway

    The terminal calls the Mainstreet gateway over its existing network connection. One pairing request returns an API key — no new hardware, no firmware swap.

  2. 02Waiting

    Send the payment

    The terminal requests a charge. The gateway builds the Solana transaction, the customer's wallet signs it, and the signature hits the wire.

  3. 03Waiting

    Settle on-chain

    The gateway wires the transaction to Solana, confirms it, and fires a webhook back to the POS. The receipt prints before the card slip would.
