MetaMask Inpage Provider

The inpage Ethereum provider object injected by MetaMask into web pages. Contains a lot of implementation details specific to MetaMask, and is probably not suitable for out-of-the-box use with other wallets.

Installation

yarn add @metamask/inpage-provider

Usage

import { initProvider } from "@metamask/inpage-provider";

// Create a stream to a remote provider:
const metamaskStream = new LocalMessageDuplexStream({
  name: "inpage",
  target: "contentscript",
});

// this will initialize the provider and set it as window.tolar
initProvider({
  connectionStream: metamaskStream,
});

const { tolar } = window;

Do Not Modify the Provider

The Provider object should not be mutated by consumers under any circumstances. The maintainers of this package will neither fix nor take responsbility for bugs caused by third parties mutating the provider object.
