base

An implementation of MetaMask's Keyring interface, that uses a WalletS1 hardware wallet for all cryptographic operations.

There are a number of differences:

• Because the keys are stored in the device, operations that rely on the device will fail if there is no WalletS1 device attached

• It does not support the decryptMessage, exportAccount methods, because own devices do not support these operations.

• Because extensions have limited access to browser features, there's no easy way to interact wth the Hardware wallet from the MetaMask extension. This library implements a workaround to those restrictions by injecting (on demand) an iframe to the background page of the extension, (which is hosted here).

The iframe is allowed to interact with the WalletS1 device (since U2F requires SSL and the iframe is hosted under https) using the libraries from browser-wallet and establishes a two-way communication channel with the extension via postMessage.

usage

1. npm i @wangkaixuan/wallets1-keyring or yarn add @wangkaixuan/wallets1-keyring
2. example, see wallets1-keyring-demo for detail.

   const WalletIOKeyring = require('@wangkaixuan/wallets1-keyring');
   let ins = new WalletIOKeyring();
   console.log('addAccounts:', await ins.addAccounts(2));
   console.log('getAccounts:', await ins.getAccounts());
   console.log('serialize:', await ins.serialize());
