Basic Usage

import signer, { unsigner } from '@cryptape/cita-signer'

const transaction = {
  privateKey: '0x7cc34429d268cdf33e1595d9aa3c56bfcb785c24b7f6dd031fe059d93d8e92d9',

  chainId: 1,
  version: 2,
  validUntilBlock: 999999999,
}

const signed = sign(transaction)
const unsignedTransaction = unsigner(signed)

In the case of no private key

If the transaction has no private key and web3.eth.accounts.wallet is empty, the returned msg will be plain transaction.
