* `keychain.js` - Keychain class with ws connection initialization
* `index.js` - override `web3.eth.accounts.signTransaction` method
* `test.js` - example usage together (`keychain` + `web3`)
**Usage**
* Sign ethereum transaction
```javascript
const { Keychain, keychainWeb3 } = require('keychain.js');
const Web3 = require('web3');
const API_KEY = 'https://ropsten.infura.io/v3/YOUR_ID';
const web3 = new Web3(new Web3.providers.HttpProvider(API_KEY));
const transactionParams = {
to: '0xE8899BA12578d60e4D0683a596EDaCbC85eC18CC',
value: 100,
gas: 21000
};
// now we are using web3 with keychain
web3.eth.accounts.signTransaction = keychainWeb3.signTransaction.bind(web3);
const keychain = new Keychain();
keychain.selectKey()
.then(publicKey => web3.eth.accounts.signTransaction(transactionParams, publicKey));
```
* Sign & build ready for broadcast bitcoin transaction
```javascript
// import library
import { bitcoin, Keychain } from 'web3override';
// tx - bitcoin.TransactionBuilder instance with inputs & outputs
const keyInstance = await Keychain.create();
const data = await keyInstance.selectKey();
const publicKey = data.result;
tx.inputs.forEach((input, index) => {
tx.prepareTx(index, publicKey)
});
const txRawHex = await tx.buildTxKeychain(keyInstance, publicKey);
```
**Run tests**
```
npm run test
```
Add key to your `key_data`:
```
keyname: test1@76de427d42c38be4
password: qwe
```
