Ramp Instant iOS SDK consists of two main types: RampInstantConfiguration and RampInstantManager.

RampInstantConfiguration contains all the information necessary for RampInstant to initialize.

  • hostLogoUrl: URL to your app's logo
  • hostAppName: your app's name
  • userAddress: 0x-prefixed ETH address of the buyer
  • swapAsset: 'ETH' or 'DAI' (optional)
  • swapAmount: int string - wei or token units (optional)
  • webhookStatusUrl: your URL for webhook updates (optional)
  • url: allows to provide an alternative URL to load a non-production version of the widget (optional)

RampInstantManager is the main class. It allows to present the RampInstant widget, listen for events, and log debug information.

  • init(configuration: RampInstantConfiguration): create instance of RampInstantManager with configuration of your choice
  • presentWidget(on viewController: UIViewController, animated: Bool): display RampInstant widget on any view controller

Example integration code

To start using RampInstant in your app, simply create a Configuration instance with parameters of your choice, then instantiate the RampInstantManager with the Configuration instance. Now you can present it anywhere!

    @IBAction func showRampInstantAction(_ sender: UIButton) {
        let configuration = RampInstant.Configuration(

            swapAmount: "1500000000000000000", // 1.5 ETH in wei
            url: "" // Development version of the widget

        rampInstantManager = RampInstantManager(configuration: configuration)
        rampInstantManager!.presentWidget(on: self, animated: true)
