Signing a Transaction

The code snippet below signs the staking transaction with the wallet constructed earlier.:

async function signTransaction(wallet, transaction) {

  return await wallet.signTransaction({
    type: 0,
    to: transaction.to,
    from: wallet.address,
    nonce: transaction.nonce,
    gasLimit: transaction.gas,
    gasPrice: transaction.gas_price,
    data: transaction.data,
    value: transaction.value,
    chainId: ethers.toBeHex(transaction.chain_id),
  });
  
}
