Tron Signature about hdwallet HOT 17 CLOSED

@artem03 right now I am using this library to create&sign&send TRC20 TriggerSmartContract transactions without problem.
Did you try to send any?
I will check if there was any custom modification for TriggerSmartContract on my side, but as I remember I done nothing regarding to it.

@farukterzioglu I was trying to send a TRC20 TriggerSmartContract for USDT just today, and got a SIGERROR error when broadcasting.

from hdwallet.

Let me check more

Yes of course, maybe I made a mistake somewhere, but I've checked my code many times, maybe I'm just doing something wrong

from hdwallet.

@farukterzioglu Did you find any "custom modification" for the TRC20 TriggerSmartContract sign?

from hdwallet.

@artem03 Just checked and saw they are same, there is no difference between signing TRX transaction and TRC20 transaction. Both signs the txid and adds the result to the signatures field. Both signatures is 68 bytes and this works in Tron Mainnet and Shasta.

@farukterzioglu Oh, sorry, I sent a transaction to the broadcast without the fee_limit field, after adding this field everything worked, the problem can be closed, I wanted to ask if you know how to decode the data field (to get the recipient and the amount you received) when receiving the transaction block

from hdwallet.

@artem03 normal TRX transaction or TRC20 transaction?

from hdwallet.

I guess you are asking about this

Amount = Convert.ToInt64(transactionEvent.Result.Value),
From = transactionEvent.Result.From.Replace("0x", "41").ToVisibleAddress(),
To = transactionEvent.Result.To.Replace("0x", "41").ToVisibleAddress(),

with

using NBitcoin.DataEncoders;

public static string ToVisibleAddress(this string tronAddress)
        {
            if (string.IsNullOrWhiteSpace(tronAddress))
            {
                return null;
            }

            byte[] bytes = tronAddress.FromHexToByteArray();
            return Encoders.Base58Check.EncodeData(bytes);
        }
        
public static byte[] FromHexToByteArray(this string input)
        {
            var numberChars = input.Length;
            var bytes = new byte[numberChars / 2];
            for (var i = 0; i < numberChars; i += 2)
            {
                bytes[i / 2] = Convert.ToByte(input.Substring(i, 2), 16);
            }
            return bytes;
        }

Not sure what exactly I need, I asked about Data in TriggerSmartContract, I use the following code to encode the data

public class TestParamsInput
	{
		[Parameter("address", 1)]
		public string First { get; set; }
		[Parameter("uint256", 2)]
		public UInt64 Second { get; set; }
	}
var abiEncode = new ABIEncode();
var data = abiEncode.GetABIParamsEncoded<TestParamsInput>(new TestParamsInput() { First = "address", Second = UInt64.Parse("amount") });

But I don't know how to decode them

from hdwallet.

can you paste the encoded data here

from hdwallet.

"00000000000000000000000033a53245269c4706e378e7c58788bfb47c8d4fbd00000000000000000000000000000000000000000000000000000000000f4240"

from hdwallet.

not sure this what you want but you can check this request:

Thanks, it will help me

from hdwallet.

to decode that kind of data, I use Nethereum heavily

some code to give an idea:

_contractBuilder = new ContractBuilder(abi, contractAddressVisible);
_contract = new Nethereum.Contracts.Contract(null, abi, contractAddressVisible);

...

public Function GetFunction(string functionName)
        {
            return _contract.GetFunction(functionName);
        }
        
public TReponse DecodeSimpleResponse<TReponse>(string functionName, string data)
        {
            Function function = GetFunction(functionName);
            return function.DecodeSimpleTypeOutput<TReponse>(data);
        }

May you please help me with some c# code how to transfer Trc20 contract balance to another trx wallet? both creating the transaction signing and broadcasting to the network

Hey, I have the similar problems, might need your help. Can you do me a favor?
