[Help] how to decode transaction? i can not broadcast tx to blockchian.

[weixuefeng]

when i post this transaction to rpc, i got response only hash, and i can not found it on blockchain or any error message. i want to know where my problem is ?

sdk is: wallet-core, like this

code:

Future<String> signTransaction(String toAddress, String privateKeyHex,
      BigInt amount, String? encodedContractData) async {
    var expire =
        (DateTime.now().microsecondsSinceEpoch / 1000000 + 300).toInt();
    Log.d("expire: $expire");
    var transfer = Everscale.Transfer(
        amount: $fixnum.Int64(amount.toInt()),
        expiredAt: expire,
        to: toAddress,
        behavior: Everscale.MessageBehavior.SimpleTransfer,
        bounce: false,
        encodedContractData: encodedContractData);
    var signingInput = Everscale.SigningInput(
        transfer: transfer, privateKey: privateKeyHex.toUint8List());
    var signed = AnySigner.sign(
        signingInput.writeToBuffer(), TWCoinType.TWCoinTypeEverscale);
    Everscale.SigningOutput output = Everscale.SigningOutput.fromBuffer(signed);
    return output.encoded;
  }

result:

   var data =
   "te6ccgICAAQAAQAAAUoAAAPhiAHTB1Uvjerh0Tw4uwZOfH3sWlUBz/l/PF6gz1UmjK+GRhGLPQae5CBpkmxN+YuMpdAiHwYVzS9XfWuSNnplma1Z9fVp8eQ/Fbs5iYsHEk7jx6OvCi/HamAqFJiQJ2v2J6EAaXUlsUy/VG7gAAAAAHAAAwACAAEAaEIAYCUduyOdc1Ge+0Ux+ghMmxAxYzRJ8AMiyXinOzK3tb4h3NZQAAAAAAAAAAAAAAAAAAAAUAAAAABLqS2KpIIs9RVh0XO9boobPTIgF0wzH20xTuYEsWsHcGnE6X4A3v8AIN0gggFMl7ohggEznLqxn3Gw7UTQ0x/THzHXC//jBOCk8mCDCNcYINMf0x/TH/gjE7vyY+1E0NMf0x/T/9FRMrryoVFEuvKiBPkBVBBV+RDyo/gAkyDXSpbTB9QC+wDo0QGkyMsfyx/L/8ntVA==";
    var hash =
      "89b5f22912ce05f0cb33944e6ed5ae4c6536c58b3d7e649f30cdf03108fb51d4";
    var res = await client.sendTransaction(data, hash);

and i got graphql result:

89b5f22912ce05f0cb33944e6ed5ae4c6536c58b3d7e649f30cdf03108fb51d4

but i can not found it on blockchain. what is my problem?

how can i check my transaction right or wrong by myself?
