A stablecoin payout, on-ramp to off-ramp

1. 1

   message

   A US company tells its bank to fund the payout. An instruction in US dollars; no token, no border crossing yet.

2. 2

   moneySame day to T+1 (ACH/wire)

   Real dollars move to a regulated on-ramp (an exchange or payment firm). This is the on-ramp: cash in.

   ▲Where people get burned

   Your risk lives at the ramps, not the chain

   The on-chain leg is robust, but the regulated on-ramp and off-ramp custody the funds in between, and they are the points that can freeze an account, stall on a compliance check, or fail outright. The boundary where fiat meets token is where people get burned, far more than the blockchain itself.

   moneyMinutes

   The on-ramp turns those dollars into USDC, a stablecoin minted one-for-one against dollars held in reserve.

4. 4

   moneyNear-instant (on-chain, final after N confirmations)← the gap most people miss

   The on-ramp sends the USDC across a public blockchain. This is the part that actually crosses the border, and it's value moving, not a bank message.

   ✗Myth vs reality

   Only the middle leg is crypto

   Myth: a stablecoin payment is crypto end to end. Reality: the company pays ordinary dollars and the supplier receives ordinary euros. Only the middle hop is on-chain. The on-ramp and off-ramp are where fiat becomes token and back, and most of the flow is conventional banking bookending one blockchain transfer.

5. 5

   moneyPer block

   Someone has to pay the network to record the transfer: the on-ramp pays a gas fee, not the company.

6. 6

   moneyFinal after N confirmations

   After enough confirmations, the USDC lands in the off-ramp's wallet. Finality here is the blockchain's, not a bank's.

   What 'final' means on-chain

   On-chain finality is probabilistic, not a legal moment a central bank declares. Validators confirm the transfer block by block, and the receiver treats it as settled only after enough confirmations. It's fast, but 'final' is a confidence threshold the off-ramp chooses, not a stamp from a settlement authority.

7. 7

   message

   Alongside the transfer, the two firms exchange data on who's paying whom. A compliance message, no money.

   ❖Why we're sure

   Why we're sure

   The originator and beneficiary data the two firms exchange is the FATF Travel Rule for virtual-asset service providers, carried by standards like IVMS 101. It is a messaging obligation that rides alongside the on-chain value transfer, not part of the money movement.

8. 8

   moneyMinutes to T+1

   The off-ramp redeems the USDC back to dollars; the issuer burns the tokens and releases the reserve dollars. This is the off-ramp: tokens back to cash.

   ↳Going deeper

   The issuer governs the reserve, not the payment

   The USDC issuer mints and burns one-for-one against dollar reserves and attests to them, but it never custodies or routes this payment. The value moves peer-to-peer between the on-ramp and off-ramp on-chain. The trust is in the reserve and the right to redeem, not in a payment rail the issuer runs.

9. 9

   moneyT+0 / T+1 (SEPA)

   The off-ramp converts dollars to euros at its own rate (the FX, and its spread, happen here) and pays out over SEPA.

   Where the FX (and its cost) really is

   The dollars-to-euros conversion and its spread happen at the off-ramp's desk, not on-chain. The blockchain only moved a dollar-denominated token; the currency switch is a conventional FX trade with a conventional margin, applied right before the SEPA payout.

10. 10

    moneySame day

    The supplier's bank credits them in euros. From their side, a normal euro payment simply arrived.
