$transaction = new Transaction ($nonce, $gasPrice, $gasLimit, $to, $value);
$transaction->getRaw ($privateKey);
// f86d048503f5476a0083027f4b941a8c8adfbe1c59e8b58cc0d515f07b7225f51c72882a45907d1bef7c00801ba0e68be766b40702e6d9c419f53d5e053c937eda36f0e973074d174027439e2b5da0790df3e4d0294f92d69104454cd96005e21095efd5f2970c2829736ca39195d8

With different chainId

use kornrunner\Ethereum\Transaction;

$nonce    = '04';

Create a EIP1559 transaction

use kornrunner\Ethereum\EIP1559Transaction;

Smart Contract to Wallet

Can I use that script to send a specific ERC20 token from a smart contract to a wallet? Thanks!

Error: invalid sender

I'm trying to send a transaction for signature, in response I get an error: Invalid sender

Example code

$nonce = '01';
$gasPrice = '03f5476a00';
$gasLimit = '027f4b';

    $transaction = new Web3Transaction(
        sprintf('0x%s', $nonce),
        sprintf('0x%s', $gasPrice),
        sprintf('0x%s', $gasLimit),
        '0x89ece67cad34d1c248fdd1d34a1008a3a67209bb',
        $dataUser->address,
        '1000000000000000000',
    );

    $signedTx = $transaction->getRaw($dataUser->private_key, 56);

    $web3->getEth()->sendRawTransaction(sprintf('0x%s', $signedTx), function ($err, $tx) use (&$result) {
        if ($err !== null) {
            throw new \Exception($err->getMessage());
        }

        $result = $tx;
    });

    dd($result);

Doesn't work when the nonce is 0

RLP encoding error when broadcasting the tx via etherscan. Will fix myself if you don't manage before!

Messing up nonce for specific nonce and chain id

So I saw that when using chainId 56(bsc mainnet) and nonce 180, the nonce is signed as 0

Does this work with vechain(vet)?

https://www.vechain.org/ this network.

I am trying to generate a HEX using chain ID 56, and after the sign, when I decode it, seems that uses another "sender" than the one of the private key, when generating the transaction.
By using same private key and changing only amount: from 0.1 to 0.01, changes the sender.

EIP1559 Transaction

Enable to support EIP1559 transaction

Can I use from this to create transaction in Erc20 tokens?

I am currently using your package to generate transaction raw and sign it in ETH, now I want to create a transaction for tokens (ex.Tether). Can I use this package? If yes please tell us how.

the heco erc20 doesn't work

error: insufficient funds for gas * price + value

chainID 128 enough balance

Call to undefined function Mdanter error

When I use your code and execute it after chanding with my own values, I am receiving this error:
PHP Fatal error: Uncaught Error: Call to undefined function Mdanter\\Ecc\\Curves\\gmp_init() in /var/www/html/vendor/mdanter/ecc/src/Curves/SecgCurve.php:122

May you tell me pleae what is this problem for and how can I solve it? Maybe I had a mistake, or the code has a bug!
