Detecting the Provider

PreviousGetting Started with Ethereum and EVMNextEstablishing a Connection

Last updated 1 year ago

To detect if a user has already installed Broearn Wallet, a web application should check for the existence of a bw object. Broearn Wallet's browser extension and mobile in-app browser will both inject a bw object into the of any web application the user visits.

If a bw object exists, Ethereum dApps can interact with Broearn Wallet via the API found at window.bw.eth. This ethprovider is also made available at window.ethereum but is prone to namespace collisions from other injected wallets.

If Broearn Wallet is not installed, we recommend you redirect your users to . Altogether, this may look like the following.

const getProvider = () => {
  if ('bw' in window) {
    const anyWindow: any = window;
    const provider = anyWindow.bw.eth;
   
    if (provider) {
      return provider;
    }
  }

  window.open('https://broearn.com/', '_blank');
};
