# Open Banking Payout (USDC → EUR)

<figure><img src="/files/swp0zmHqNbwgfME6QmmB" alt=""><figcaption></figcaption></figure>

This section provides a reference for integrating Tylt CrossRamp’s Open Banking off-ramp flow within merchant applications.

Through this integration, merchants can initiate transfers of stablecoins (USDC) to end users, who can subsequently convert the received crypto-assets into fiat via Open Banking rails.

{% hint style="warning" %}
Open loop Open-Banking Payouts are only available for EUR currency. Support for GBP will be available shorlty.
{% endhint %}

### Conversion & Settlement Model

1. Each transaction is processed using a **real-time conversion quote**.
2. At the time of initiation, a USDC → EUR quote is generated. The merchant initiates a transfer of stablecoins to the end user, who reviews and accepts the off-ramp quote and proceeds with the transaction based on the provided details.
3. The end user then completes the off-ramp flow, following which the corresponding crypto-asset conversion is executed and the resulting fiat amount is made available via SEPA Instant.
4. All transactions are reconciled through a daily settlement cycle, ensuring that balances are fully reflected no later than **2:30 AM UTC**.
