use Nebulas\Core\TransactionCallPayload;

$neb = new Neb();
$neb->setProvider(new HttpProvider("https://testnet.nebulas.io"));

$keyJson = '{"version":4,"id":"814745d0-9200-42bd-a4df-557b2d7e1d8b","address":"n1H2Yb5Q6ZfKvs61htVSV4b1U2gr2GA9vo6","crypto":{"ciphertext":"fb831107ce71ed9064fca0de8d514d7b2ba0aa03aa4fa6302d09fdfdfad23a18","cipherparams":{"iv":"fb65caf32f4dbb2593e36b02c07b8484"},"cipher":"aes-128-ctr","kdf":"scrypt","kdfparams":{"dklen":32,"salt":"dddc4f9b3e2079b5cc65d82d4f9ecf27da6ec86770cb627a19bc76d094bf9472","n":4096,"r":8,"p":1},"mac":"1a66d8e18d10404440d2762c0d59d0ce9e12a4bbdfc03323736a435a0761ee23","machash":"sha3256"}}';
$password = 'passphrase';

$from = Account:: fromKey($keyJson, $password);

//get nonce value
$resp = $neb->api->getAccountState($fromAddr);
$respObj = json_decode($resp);
$nonce = $respObj->result->nonce;

//make new transaction
$chainId = 1001;
$to = "n1H2Yb5Q6ZfKvs61htVSV4b1U2gr2GA9vo6";
$tx = new Transaction($chainId, $from, $to, $value = "0", $nonce + 1 );
$tx->hashTransaction();
