Overview

The swap widget, powered by Quickswap, facilitates token exchanges on Immutable zkEVM.

The Immutable Marketplace package generates the URL required to access the widget.

Generating the swap URL

To generate the swap URL, provide the following details:

Environment – Choose either sandbox or production.
Publishable key – Available from Immutable Hub. Follow the steps on this page to create your publishable key.

using Immutable.Marketplace;
using UnityEngine;

public class MarketplaceExample : MonoBehaviour
{
    async void Start()
    {        
        try
        {
            string link = LinkFactory.GenerateSwapLink(
                environment: Environment.Sandbox, 
                publishableKey: "YOUR_PUBLISHABLE_KEY"
            );
            Debug.Log($"Link: {link}");
            
            // Open the generated link in the default browser
            Application.OpenURL(link);
        }
        catch (System.Exception e)
        {
            Debug.LogError($"Error getting the swap link: {e.Message}");
        }
    }
}

Configuration

You can pass optional configurations to the swap widget using the GenerateSwapLink function. The main configurations are provided through the SwapQueryParams struct.

The SwapQueryParams struct allows you to define the configuration for the swap flow. Here's a list of the available fields:

Parameter	Description
`FromTokenAddress`	The address of the token being swapped from (default: null).
`ToTokenAddress`	The address of the token being swapped to (default: null).

Here's an example of how to use the GenerateSwapLink function with the SwapQueryParams struct:

var link = LinkFactory.GenerateSwapLink(
    environment: Environment.Sandbox,
    publishableKey: "YOUR_PUBLISHABLE_KEY",
    queryParams: new SwapQueryParams
    {
        FromTokenAddress = "0x1234...abcd",
        ToTokenAddress = "0xabcd...1234"
    }
);
