Flow

This document provides an overview of the cross-chain transaction flow using the Interop SDK. It illustrates how a developer can interact with different cross-chain protocols to obtain quotes, execute transactions, and track them on-chain.

Flow Stages​

1. Quote Phase​

The developer requests a quote from the SDK, which queries the provider protocol for pricing and availability.

2. Execution Phase​

After selecting a quote, the developer sends the prepared transaction to the blockchain.

3. Tracking Phase​

Once the transaction is submitted, the developer can use the Order Tracker to monitor the cross-chain transfer status in real-time, receiving updates as the order progresses (typically Pending → Finalized, or Failed / Refunded).

Additional Features​

The SDK also supports:

  • Quote Aggregation: Compare quotes from multiple providers simultaneously
  • Order Tracking: Monitor cross-chain transfers from initiation to completion
  • Error Handling: Graceful handling of timeouts and provider errors

See the Order Tracking and Advanced Usage guides for more details.
