Transaction not getting broadcasted

Questions
1

Hello,

I am trying to send ethereum from 1 address to another using php, and everything looks fine but the transaction is not showing up on the network.

I am using this package to make a connection with infura: allmediaindo/infura

I am using this package to create & sign a transaction: web3p/ethereum-tx

This is the code I am currently using to create, sign and send the transaction:

use allmediaindo\Infura\Infura;
use Web3p\EthereumTx\EIP2930Transaction;
  
$transaction = new EIP2930Transaction([
    'nonce' => '0x01',
    'from' => '0x70abb694597d4b902e4be55429599a703bd1c3bd',
    'to' => '0x4be102722f7370ad987f82fbdfa19532141f8b70',
    'gas' => '0x' . dechex(50000),
    'gasPrice' => '0x' . dechex(20000000000),
    'value' => '0x' . dechex(10000000000000000), //0.01eth
    'chainId' => 1,
    'accessList' => [],
    'data' => ''
]);

$signedTransaction = '0x' . $transaction->sign($privateKey);

$client = new Infura('mainnet', $infuraProjectID);
$tx = $client->eth_sendRawTransaction($signedTransaction);

The signedTransaction outputs:

0x01f86d01018504a817c80082c350944be102722f7370ad987f82fbdfa19532141f8b70872386f26fc1000080c001a0408ffef7134ea97f01f44350460ef0229e6065ba29ca89286e3d7f0eef13e8f4a01754d367205c0fbca42ceb3e1bc7ba2360ad790afe3f0b42fbaf4dd471d11c13

And this is the final hash:

0xd1af846358e37bea78a28773f10cc68fde6cd9a58f708da0c9847c2145ef7784

I’ve tried using MyCrypto - Ethereum Wallet Manager to manualy send the signed transaction, everything looks good, but it doesn’t show up on the network.

I’m not sure if my gas & gasPrice is good, but if I’m right it is way over the recommended amount.

I am struggling with this for a couple of days now already, so any help would be more than welcome!

Have a good one :slight_smile:

Hey, at the first look I’d say the nonce is the problem, it should be 0x0 because you haven’t sent any txns yet from that account.

Thank you very much, changing the nonce to 0 fixed it!

I didn’t understand what nonce actualy was for, but it is the outgoing transaction count from the sender address right?

Hi @Luxiflex, that’s correct - the nonce is the number of transactions sent from a specific address.
