Cross-Chain Swap Using Squid Router

Overview

The Cross-Chain Swap feature allows users to seamlessly exchange tokens between different blockchain networks using our decentralized exchange (DEX). This functionality leverages the Squid Router API to facilitate efficient and secure token swaps. This documentation provides a detailed explanation of how the cross-chain swap process works, ensuring users understand the steps involved in executing a swap.

Key Features

• Multi-Chain Support: Users can swap tokens across various blockchain networks.

• Real-Time Token Prices: The application fetches up-to-date token prices to ensure accurate swap calculations.

• User-Friendly Interface: The DEX provides an intuitive interface for selecting tokens, inputting amounts, and confirming swaps.

• Error Handling: Comprehensive error handling ensures users are informed of any issues during the swap process.

Step-by-Step Process

Step 1: User Interface Interaction

Users begin by navigating to the Cross-Chain Swap section of the DEX. Here, they can select the source and destination blockchain networks, as well as the tokens they wish to swap. The interface is designed to be user-friendly, guiding users through the selection process.

Step 2: Token Selection

Once the user selects the source and destination chains, they can choose the tokens they want to swap. The DEX displays a list of available tokens for each chain, allowing users to make informed decisions based on their preferences.

Step 3: Input Amount

After selecting the tokens, users input the amount they wish to swap. The DEX performs real-time validation to ensure that the input amount meets the minimum requirements for the swap (e.g., a minimum value of $5).

Step 4: Fetching Swap Route

Upon entering the amount, the DEX automatically fetches the optimal swap route using the Squid Router API. This process involves sending a request that includes the selected tokens, amounts, and user address. The API returns the best route for the swap, including estimated amounts and any applicable fees.

Step 5: Approval for Token Spending

Before executing the swap, the DEX checks whether the user has approved the necessary token spending. If the allowance is insufficient, the DEX prompts the user to approve the required amount. This step is crucial for ensuring that the DEX can execute the swap on behalf of the user.

Step 6: Confirming the Swap

Once the user has approved the token spending, they can confirm the swap. The DEX constructs the transaction data and initiates the swap process. Users are presented with a summary of the transaction, including the tokens being swapped, amounts, and estimated fees.

Step 7: Executing the Transaction

The DEX sends the transaction to the blockchain, executing the swap. Users receive real-time updates on the transaction status, ensuring transparency throughout the process. If the transaction is successful, users are notified with a confirmation message and provided with the transaction hash for tracking purposes.

Step 8: Error Handling and Notifications

In the event of an error during the swap process, the DEX provides clear and informative error messages. This ensures that users understand the nature of the issue and can take appropriate action, whether it be adjusting their input or checking their wallet settings.

Step 9: Transaction History

After the swap is completed, the DEX records the transaction details, allowing users to view their swap history. This feature enhances user experience by providing transparency and accountability for all transactions conducted on the platform.

Conclusion

The Cross-Chain Swap feature on our DEX, powered by the Squid Router API, offers users a robust and efficient way to exchange tokens across different blockchain networks. By following the outlined steps, users can easily navigate the swapping process, ensuring a seamless experience.
