# Cross-Chain Swap API Handling

#### **Configuration:**

Ordiswap is configured with retry and rate-limiting capabilities. This ensures robustness in case of network issues and prevents abuse of the Thorswap API by limiting the number of requests per second.

***

#### **API Endpoints:**

Ordiswap defines constants for Thorswap API endpoints (`THORSWAP_STATUS_API` and `THORSWAP_QUOTE_API`), which are used for checking the status of swaps and obtaining quotes for swap transactions.

***

####  **Quote Retrieval:**

`getThorswapQuote`: Retrieves a quote for a swap transaction based on specified parameters like source asset, target asset, amount, and destination.

***

#### **Order Management in MongoDB Collection:**

`getOrder`: Retrieves a  order from the DB collection based on a given filter.

`addOrder`: Adds a order to the DB collection. It checks if the order already exists and processes the order after insertion.

***

**Order Processing:**

`processOrder`: Processes a order by checking the status of the corresponding swap on Thorswap. If the swap has been finalized, it updates the order status and details in the DB collection.

***

**Order Status Constants:**

Ordiswap defines constants (`ORDER_STATUS_ORDERED`, `ORDER_STATUS_FAILED`, `ORDER_STATUS_SUCCESS`) representing different states of orders.

***

**Error Handling:**

Ordiswap includes error handling for HTTP requests and other potential errors during order processing. It logs errors for further analysis.

***

#### System Flow:

#### **Order Placement:**

Users can add a order (`addOrder`) by providing an order ID. The system checks if the order already exists and, if not, adds it to the DB collection.

**Order Processing:**

The background thread (`thorswapThread`) continuously processes orders. It checks the status, updates the order details, and finalizes orders when applicable.
