Collected fiat is converted to stablecoin and credited to the merchant’s pool wallet, rather than to any individual user wallet. This accumulates as reusable liquidity — for example, to fund Pool Sell payouts on the offramp side through the same pool.

Fiat payment is collected from the user via the applicable payment method (bank transfer, Open Banking, ACH Pull, etc., depending on corridor).
2
Initiate Onramp
The onramp (Pool Buy) is initiated for the user.

Settlement
Fiat is converted to stablecoin and credited to the pool wallet.
Liquidity credited via Pool Buy is reusable — it becomes available balance for offramp Pool Sell transactions, letting fiat collected on the onramp side directly fund payouts on the offramp side. See Onramp Fund Management.
