This example demonstrates how to use Ethereum browser wallets like Metamask or Nifty as a signers for Feeds.

Prerequisites

• Node and NPM
• browser with Ethereum compatible wallet like Metamask or Nifty
• Bee instance running with API port on 1633 and Debug API port on 1635 and having flag --cors-allowed-origins="*"

Steps:

1. Run npm install and npm start
2. Put some message, topic and hit the "Sign and upload!" button
3. Authenticate the message with your wallet For your own safety use an account without any real funds!!!
4. Open the created link and see your message
5. Now put some other message and upload it and refresh the page to see the content changed under the same URL

Be aware! The wallets won't be injected into files served using file:// in browsers! Load src/index.html with the development server which is run with the npm start!

Code

Tip! Checkout the browser console to see the steps the example is doing!

The interesting code parts are found in src/main.ts file. We are using utility supplied by bee-js called makeEthereumWalletSigner that takes EIP-1193 compatible Ethereum provider and create custom Signer.
