Transaction signing - Githubissues

ErkanKule commented 5 years ago

Hi ,

There is no sample for transaction signing

I has a transfer contract for TRX ,

        TransferContract trx = new TransferContract();
        trx.Amount = 100;
        trx.OwnerAddress = Google.Protobuf.ByteString.CopyFrom("TPMcVMR5PsGqsywBtXmjwxEVTtmBzWYaJv", Encoding.ASCII);
        trx.ToAddress = Google.Protobuf.ByteString.CopyFrom("TYZ9AYiuCsNyzhYGosUE1Zeay6DLn96w5p", Encoding.ASCII);

I had private key or ECKey too ,

what next to sign trx in c# ?

@ErkanKule Have you found a solution to your question? If so, could you share how to sign a transaction directly in C #

any news? it really should be with some sample code

EnjoX commented 3 years ago

I did it this way but im not sure if its correct, but would be nice if u can test ist.

private const string SignAlgorithmName = "SHA-256withECDSA"; public byte[] SignTransaction(byte[] data) { ISigner signer = SignerUtilities.GetSigner(SignAlgorithmName); signer.Init(true, _privateKey); signer.BlockUpdate(data, 0, data.Length); byte[] sigBytes = signer.GenerateSignature(); return sigBytes; }

and how do you send it to the blockchain? i appreciate if you send full sample of your solution.

I have never tried. Its documented at https://developers.tron.network/docs/account If you want to test it you can use https://developers.tron.network/reference#walletbroadcasttransaction-1 I will also test it if i have time

Does anyone have a full example of signing and broadcasting?

Not with this library, but check this out: https://github.com/stoway/TronNet#sample-3-contract-trc20-transfer-usdt

I used it in dotnet core... you should implement it in .net 4.7 yourself .

@MRayp ok. because .net framework does not support grpc ... .thank you
