I'm trying to make an ethereum raw transaction by php and these libraries:
https://github.com/simplito/elliptic-php
https://github.com/kornrunner/php-keccak
this is my code:
use Elliptic\EC; use kornrunner\Keccak; use Web3p\RLP\RLP; $privateKeyHex = '.....'; // wallet private key $toWallet = '118086be6247fBDa3BC64B4A11F07F3894aA1fAF'; $ec = new EC('secp256k1'); $key = $ec->keyFromPrivate($privateKeyHex ); $publicKeyHex = $key->getPublic('hex'); // $publicKeyHex => 0445e2caf0f227247dfa10440765812492e4d4c9df7b4e74d0d5cd3279fa80f5ef987a70e061ca20c06f09690957c9ba365cf06541181d1291e14c847d0d826583 $nonce= 0; $gasPrice = 1e10; $gasLimit = 21000; $to = hex2bin($toWallet); $value = 1e15-($gasLimit*$gasPrice)-1; $inputData = 0; //*********** EIP_155 ********* $chain_id = 1; $r = 0; $s = 0; //***************************** $SignData = [$nonce,$gasPrice,$gasLimit,$to,$value,$inputData,$chain_id,$r,$s]; $SignRlpData = rlpEncode($SignData); $signHash = Keccak::hash(hex2bin($SignRlpData), 256); $signature = $ec->sign($signHash ,$key); $r = $signature->r->toString('hex'); $s = $signature->s->toString('hex'); $v = $chain_id*2 + ($signature->recoveryParam +35); $trxData = [$nonce,$gasPrice,$gasLimit,$to,$value,$inputData,$v,hex2bin($r),hex2bin($s)]; $trxRlpData = rlpEncode($trxData ); // trxRlpData => f86b808502540be40082520894118086be6247fbda3bc64b4a11f07f3894aa1faf8702ce80355f5fff8026a0d879bd4319788f5e75fba039f879f7b38f25a80d1b6768f8c80d2e0dec7dc11aa0d952e26360e25f95821fc7f92d231925cd0cd1c412fc1d4b5bbdb439fbf0f19b function rlpEncode($a){ $rlp = new RLP; $encodedBuffer = $rlp->encode($a); return $encodedBuffer->toString('hex'); } now after I send value of $trxRlpData to the ethereum network by https://etherscan.io/pushTx, show me this error message:
Error! Unable to broadcast Tx : {"jsonrpc":"2.0","id":1,"error":{"code":-32000,"message":"invalid sender"}} but where is problem ?
