Installation

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

Initialize the BEVM Controller class

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

const bevmController = 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' });
    },
  },
});

const keyringState = await bevmController.createNewVaultAndKeychain(password);

Restore a keyring with the first account using a mnemonic

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

Add a new account to the keyring object

const keyringState = await bevmController.addNewAccount(keyringObject);

Export the private key of an address present in the keyring

const privateKey = await bevmController.exportAccount(address);

Sign a transaction

const signedTx = await bevmController.signTransaction(bevmTx, _fromAddress);

Sign a message

const signedMsg = await bevmController.signMessage(msgParams);

Sign a message
