Insufficient funds when sending a transaction

[kielabokkie]

First of all, great work on this @sc0Vu! I know this is still bleeding edge at the moment but I encountered an issue that I hope you can help me out with. Below is a snippet from my proof of concept code to send transactions on the rinkeby testnet.

$web3 = new Web3(new HttpProvider(new HttpRequestManager(env('INFURA_URL'), 5.0)));
$eth = $web3->eth;

$eth->getBalance(env('WALLET_ADDRESS'), function ($err, $balance) {
    if ($err !== null) {
        $this->error($err->getMessage());
    }
    $this->comment(sprintf('Current balance: %s ETH', wei_to_ether($balance)));
});

$eth->gasPrice(function ($err, $gasPrice) {
    if ($err !== null) {
        $this->error($err->getMessage());
    }
    $this->gasPrice = $gasPrice;
    $this->comment(sprintf('Gas price: %s gwei', wei_to_gwei($gasPrice->toString())));
});

$eth->estimateGas(['from' => env('WALLET_ADDRESS')], function ($err, $gas) {
    if ($err !== null) {
        $this->error($err->getMessage());
    }
    $this->gasEstimate = $gas;
    $this->comment(sprintf('Gas limit: %s units', $gas->toString()));
});

$eth->getTransactionCount(env('WALLET_ADDRESS'), 'pending', function ($err, $nonce) use ($eth) {
    if ($err !== null) {
        $this->error($err->getMessage());
    }
    $this->comment(sprintf('Nonce: %s', $nonce));

    for ($i = 0; $i < count($this->recipients); $i++) {
        $this->info(
            sprintf(
                'Sending %s ETH to %s',
                $this->recipients[$i]['amount'],
                $this->recipients[$i]['address']
            )
        );

        // @todo: should use TransactionFormatter to do all hex conversion (when it works)
        $txParams = [
            'from' => env('WALLET_ADDRESS'),
            'to' => $this->recipients[$i]['address'],
            'value' => sprintf(decimal_to_hex(ether_to_wei($this->recipients[$i]['amount']))),
            'nonce' => sprintf(decimal_to_hex($nonce->toString() + $i)),
            'gasLimit' => decimal_to_hex($this->gasEstimate->toString()),
            'gasPrice' => decimal_to_hex($this->gasPrice->toString()),
            'chainId' => 4,
        ];

        $transaction = new Transaction($txParams);

        $signedTransaction = $transaction->sign(env('WALLET_PRIVATE_KEY'));

        // Send the transaction
        $eth->sendRawTransaction(sprintf('0x%s', $signedTransaction), function ($err, $tx) {
            if ($err !== null) {
                $this->error($err->getMessage());
            }
            $this->comment(sprintf('TX: %s', $tx));
        });
    }
});

Everything works flawlessly until sending the transaction, it comes back with the following error insufficient funds for gas * price + value. I'm sure that I have sufficient funds, as I have a very similar proof of concept using web3js that works fine. Below are the transaction parameters right before signing for both versions:

PHP

array:7 [
  "from" => "0x83ca28679f477Cd4710B72D11e47905A66dd6Dd4"
  "to" => "0xEFd7b1e4F28Dcd8000abb62974A77DB6a35618A6"
  "value" => "0x5af3107a4000"
  "nonce" => "0x89"
  "gasLimit" => "0xcf08"
  "gasPrice" => "0x3b9aca00"
  "chainId" => 4
]

Javascript

{ from: '0x83ca28679f477Cd4710B72D11e47905A66dd6Dd4',
  to: '0xEFd7b1e4F28Dcd8000abb62974A77DB6a35618A6',
  value: '0x5af3107a4000',
  nonce: '0x89',
  gasLimit: '0xcf08',
  gasPrice: '0x3b9aca00',
  chainId: 4 }

As you can see the parameters are identical so I'm a bit lost as to why the transaction doesn't get through. Any thoughts?

Hi @kielabokkie ,
Thanks for report this, I had test sendRawTransaction lots of times with ethereum-tx js library and ethereum-tx php library, tested with infura json rpc service.
Both got insufficient funds error, I still try to find what happend here.
I think it's tx library issue or api service issue, still try to find way to fix it.

@sc0Vu I got the "Insufficient funds" error today through the JS library when I passed the chain ID as a string instead of an integer. Not sure if it is related but thought I mention it 😉️

@kielabokkie I am frustrated... I am not able to call a function mutating status passing params... could you write an exmplae, because you're able to do this, please?
