USD Layer

Widget allows to quickly add Usdlayer into any web app in minutes.

The widget can either appear as a modal on top of an app, or included inside an HTML element.

If the hosting app already has a connected user with web3, this wallet can be forwarded to the widget.

🎁 Quick start

yarn add @usdlayer/widget

Start widget

// Import package
import UsdlayerWidget from '@usdlayer/widget';

// Instanciate the widget
const usdlayer = new UsdlayerWidget();

// Open the widget as a modal when you want it
usdlayer.open();

🎛 Reference

Instanciation

• new UsdlayerWidget(opts)
  Instanciate a Usdlayer widget.

opts.containerElement: Include Usdlayer inside of an HTML element on your website. If not set, the widget will appear as a modal.

opts.ethereum: A standard JSON-RPC provider. This is useful if the hosting app already authenticated the web3 wallet of the user, so he doesn't have to login again on Usdlayer.

opts.token: Automatically select a token to sell in Usdlayer. Must be an ERC20 contract address.

If used as a modal:

• usdlayer.open()
  Opens the Usdlayer widget modal.

• usdlayer.close()
  Closes the Usdlayer widget modal. Not mandatory, a button is present to enable the user to close it.
