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

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

Through this integration, end users can initiate account-to-account transfers via Open Banking, which are used to facilitate the acquisition of stablecoins. The resulting USDC is transferred to the merchant’s Tylt wallet.

***

#### Conversion & Settlement Model

1. Each transaction is processed using a **real-time conversion quote**.
2. At the time of initiation, a EUR / GBP → USDC quote is generated. The end user reviews and accepts the quote, following which the transaction is initiated to acquire the corresponding crypto-assets and transfer them to the merchant, based on the provided transaction details.
3. The end user is then prompted to complete a fiat payment via Open Banking through
4. Upon successful completion of the fiat leg, the corresponding crypto-asset conversion is executed, and the resulting USDC is credited to the merchant’s Tylt wallet.
5. Settlement is finalised through a daily reconciliation cycle, ensuring that all transactions are fully reflected in the merchant’s balance no later than **2:30 AM UTC**.
