Connecting Finnie

Web3 Browser Detection

When Finnie wallet is initialized it will emit a custom browser event called finnieWalletLoaded. You can listen for that event and set a flag in your app which would indicate that Finnie is ready to use. The example code could look like this:

let isFinnieInjected = false;
window.addEventListener("finnieWalletLoaded", () => {
  isFinnieInjected = true;
});

At this point, Finnie wallet will inject the ethereum provider object into the global window object. You can verify this by running the code:

if (typeof window.ethereum !== 'undefined' && window.ethereum.isFinnie) {
  console.log('Finnie is installed');
}
