Secure peer-to-peer connectivity between dApps and wallets

Features

• Privacy-first, end-to-end encrypted, no metrics, no tracking
• No central dependency, rather a variety of signaling layers
• Peer-to-peer transport via WebRTC (or other transport layers)
• Reuse of existing infrastructure and p2p standards
• User control over connection & configuration

Quickstart

dApp (host)

import 'package:openlv/openlv.dart';

final dapp = await OpenLv.dapp(
  info: PeerInfo(identity: 'com.example.dapp', name: 'Example dApp'),
  onRequest: (message) async {
    final request = message as Map<String, dynamic>;
    return {
      'jsonrpc': '2.0',
      'id': request['id'],
      'error': {'code': -32601, 'message': 'Method not found'},
    };
  },
);

await dapp.connect();
print('Connection URL: ${dapp.uri}'); // share with the wallet

await dapp.waitForLink();
final response = await dapp.send({
  'jsonrpc': '2.0',
  'id': 1,
  'method': 'eth_chainId',
  'params': [],
});
print('Response: $response');

await dapp.close();

Wallet (client)

final wallet = await OpenLv.wallet(
  'openlv://...', // connection URL from the dApp
  info: PeerInfo(identity: 'com.example.wallet', name: 'Example Wallet'),
  onRequest: (message) async {
    final request = message as Map<String, dynamic>;
    return {
      'jsonrpc': '2.0',
      'id': request['id'],
      'error': {'code': -32601, 'message': 'Method not found'},
    };
  },
);

await wallet.connect();
await wallet.waitForLink();
print('Connected!');

await wallet.close();

See example/ for a small Flutter app exercising both roles.

Native builds & platform setup

openlv supports Android, iOS, Linux, macOS, and Windows. Make sure you have a rust toolchain setup. And for cross-compilation you'll also need Android NDK or Xcode.

You can also adjust the hooks.user_defines.openlv.profile in your application's pubspec.yaml to debug for development.

Consumer Flutter apps need network access:

• Android: add <uses-permission android:name="android.permission.INTERNET" /> to android/app/src/main/AndroidManifest.xml.
• macOS: enable com.apple.security.network.client in both DebugProfile.entitlements and Release.entitlements when using App Sandbox.
