TajirWallet provider

Ethereum provider used by TajirWallet in web pages (window.ethereum). This package is based on the stream-connected inpage provider pattern; it keeps compatible metamask_* RPC and stream names so the extension and inpage script stay in sync.

The BaseProvider implements EIP-1193. StreamProvider adds stream-based JSON-RPC. The inpage implementation is TajirWalletInpageProvider (DevTools shows Proxy(TajirWalletInpageProvider)). The package still exports MetaMaskInpageProvider as a deprecated alias for the same class. The injected window.ethereum exposes isTajirWallet: true, _tajirwallet for the experimental API, and a _metamask getter that returns the same object for older snippets.

Usage

import { initializeProvider } from '@tajirwallet/provider';

const walletStream = new LocalMessageDuplexStream({
  name: 'inpage',
  target: 'contentscript',
});

initializeProvider({
  connectionStream: walletStream,
});

const { ethereum } = window;

Types

Types ship with the package. You may need Node types for EventEmitter and streams (e.g. @types/node).

Do not modify the provider

Do not mutate the provider object; unsupported mutations can break wallet behavior.
