## Installation

`npm install --save @getsafle/vault-rootstock-controller`

## Initialize the rootstock Controller class

```
const { KeyringController, getBalance } = require('@getsafle/vault-rootstock-controller');

const rootstockController = new KeyringController({
  encryptor: {
    // An optional object for defining encryption schemes:
    // Defaults to Browser-native SubtleCrypto.
    encrypt(password, object) {
      return new Promise('encrypted!');
    },
    decrypt(password, encryptedString) {
      return new Promise({ foo: 'bar' });
    },
  },
});
```

## Methods

```
const keyringState = await rootstockController.createNewVaultAndKeychain(password);
```

### Restore a keyring with the first account using a mnemonic

```
const keyringState = await rootstockController.createNewVaultAndRestore(password, mnemonic);
```

### Add a new account to the keyring object

```
const keyringState = await rootstockController.addNewAccount(keyringObject);
```

### Export the private key of an address present in the keyring

const privateKey = await rootstockController.exportAccount(address);
```

### Sign a transaction

```
const signedTx = await rootstockController.signTransaction(rootstockTx, _fromAddress);
```

### Sign a message

```
const signedMsg = await rootstockController.signMessage(msgParams);
```

### Sign a message

const signedObj = await rootstockController.sign(msgParams, pvtKey, web3Obj);
```

### Sign Typed Data (EIP-712)

```
const signedData = await rootstockController.signTypedMessage(msgParams);
```

### Get balance

```
const balance = await rootstockController.getBalance(address, web3);
```

### Send Transaction
