BEP-20 transaction about ethereum-tx

[sc0Vu]

Hey @Razorholt, you have to fetch nonce from blockchain state with getTransactionCount(). In EVM based blockchain, it'll checkout the nonce in their state database.

Hi Did it work?

Hello, so I am pretty new to this kind of coding and wanted to create a function to sent bnb transactions(0.1bnb gasprive 10gwei, gaslimit 21000). For now I am using the testnetwork and I just cant get it to work. Thanks in advance.

use Web3\Web3;
use Web3p\EthereumTx\Transaction;

$web3 = new Web3('https://data-seed-prebsc-1-s1.binance.org:8545');
$eth = $web3->eth;

$transaction = new Transaction([
    'nonce' => '0x' . bin2hex(makeRandomString()),
    'from' => "0x73AdF374419E4BAaDDC243e2250d6f6661D0Ff46",
    'to' => "0x367A32ba87E10e3AdAE8C60546B9383c78a3841A",
    'gas' => '0x' . dechex(21000),
    'gasPrice' => '0x' . dechex(10000000000),
    'value' => '0x' . dechex(100000000),
    'chainId' => 97
]);

$signedTransaction = $transaction->sign($privatekey);

$eth->sendRawTransaction('0x'. $signedTransaction, function ($err, $tx) {
    if ($err !== null) {
        $err->getMessage();
    }
    echo 'TX: '. $tx . PHP_EOL;
});

function makeRandomString($bits = 256) {
    $bytes = ceil($bits / 8);
    $return = '';
    for ($i = 0; $i < $bytes; $i++) {
        $return .= chr(mt_rand(0, 255));
    }
    return $return;
}`

傻屌，nonce不能用随机数，用getTransactionCount获取
