Im using "web3": "^1.0.0-beta.37"

And I want to understand How can I send rawTransaction

My code is:

const pk = 'xxxxxxx';
const rawTransaction = {
    "to": "0xa53709839ab6Da3ad9c1518Ed39a4a0fFCbA3684",
    "value": web3.utils.toWei('1', 'wei'),
    "gas": 2000000,
    "chainId": 3
};
let signedTx = await web3.eth.accounts.signTransaction(rawTransaction, pk).catch(console.dir);
let sendTx = await web3.eth.sendSignedTransaction(signedTx.rawTransaction).catch(console.error);

My account has 4Eth (on ropsten) and my httpProvider is ropsten (using infura)

but I get this error

Error: Returned error: insufficient funds for gas * price + value

I follow:

https://web3js.readthedocs.io/en/1.0/web3-eth-accounts.html?highlight=signTransaction#signtransaction

and then

https://web3js.readthedocs.io/en/1.0/web3-eth.html#eth-sendsignedtransaction

  • Most of the time when I receive that error it's due to not being fully synced with the chain. Make sure you're fully synchronized.

  • @LauriPeltonen thanks for reply, I don't have ropsten locally, I use infura to broadcast my TX. It's wrong ?

  • Oh, if you use Infura then it's synchronized. Another thing I noticed is that I'm unsure if toWei supports decimal numbers - just to be sure use only integers. Check details: web3js.readthedocs.io/en/1.0/web3-utils.html#towei

  • why from field is missing in your raw transaction?, Try adding it and run.

  • Shouldn't 21000 gas be enough for this type of transaction?

Well, the message is saying that you don’t have funds. Here’s what you can do:

  1. Double check that the pk you are using to sign that transaction is actually the private key of the account with enough balance.

  2. Double check the web3 provider is actually pointing to the same network you have ethers in. Are you sure the infura node is connected to ropsten?

  3. Try to execute getBalance() for that account and verify the output is displaying correctly your balance

  • 1. Im sure, Can I verify the integrity of signature ? 2. yes, the url is ropsten.infura.io/v3/API_KEY 3. await web3.eth.getBalance(address) => 12285448249427863490

  • Add a ‘from’ parameter to the transaction object with value your address

  • Then the problem is probably from the private key that you are using, I think it’s not correct
