• Installation
• Initialize the Velas Controller class
• Methods
  • Generate Keyring with 1 account and encrypt
  • Restore a keyring with the first account using a mnemonic
  • Add a new account to the keyring object
  • Export the private key of an address present in the keyring

  • Get balance

Installation

npm install --save @getsafle/vault-velas-controller

Initialize the Velas Controller class

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

const velasController = 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

Generate Keyring with 1 account and encrypt

const keyringState = await velasController.createNewVaultAndKeychain(password);

Restore a keyring with the first account using a mnemonic

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

Add a new account to the keyring object

const keyringState = await velasController.addNewAccount(keyringObject);

Export the private key of an address present in the keyring

const privateKey = await velasController.exportAccount(address);

Sign a transaction

const signedTx = await velasController.signTransaction(velasTx, _fromAddress);

Sign a message

const signedMsg = await velasController.signMessage(msgParams);

Sign a message

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

Sign Typed Data (EIP-712)

const signedData = await velasController.signTypedMessage(msgParams);

Raw transaction object

rawTx: {
  to,                          // receiver address
  from,                        // sender address
  value,                       // amount to send
  gas,                         // gas Limit of transaction
  gasPrice,                    // gasPrice
  data,                        // data in hex to send
  nonce,                       // transaction nonce
  chainId,                     // chainID | 111 - TESTNET, 106 - MAINNET
}

Get balance

const balance = await getBalance(address, web3);
