Initialize the widget

You can integrate the Wert Widget into your web app using our SDK, this is the recommended way to initialize the widget. For React projects, we provide this wrapper.

You can find examples of the integration on GitHub.

Our NFT checkout can also be used for any smart contract interaction such as facilating token swaps for DeFi projects. Basically anything you could do from your own wallet, we can do from ours but on on behalf of the user paying with fiat, and the best part, the end user is still the recipient of the transaction! Check out some great examples here at our Forming input datapage.

Once SDK is installed, you can use the following code snippet to initialize the payment module:

// Import the SDK
import WertWidget from "@wert-io/widget-initializer";

// Initialize the payment module
const wertWidget = new WertWidget({
  // Configuration options
  // ...
});

// Further code to handle widget events and interactions
