Jepeux vérifier la signature (SECP256K1) de latransaction contre des outilstierset vérifie (c'est-----simplement signé la valeur «hachage» correctement). J'ai utilisé lenoeud RPC 'Forge' Endpointpour vérifier la sérialisation correcte avec JSON suivant:

I am writing full custom wallet software for Tezos in C# and got the following raw transaction:

When I try to inject the raw signed transaction ('Signed') with the node rpc I get the response:
[
{
"kind": "temporary",
"id": "failure",
"msg": "Error while applying operation oozXCEKTUFcw8PHcrskvuWphiH1kNz12eohX1mp8AKinJU9fPYS:\nrefused (Error:\n The operation signature is invalid\n)"
}
]

I can verify the signature (secp256k1) of the transaction against third party tools and it verifies (that is purely that the 'Hash' value is signed correctly). I used the node rpc 'Forge' endpoint to verify the correct serialization with following JSON:
{ "branch":"BKiXcfN1ZTXnNNbTWSRArSWzVFc6om7radWq5mTqGX6rY4P2Uhe",
"contents":[{
"kind":"reveal",
"fee":"1300",
"gas_limit":"10100",
"storage_limit": "300",
"public_key":"sppk7ZjMvKgUwnjYZKoQEYaNhorr1NJxmqgHLjExsP3uq98XKChFius",
"counter":"2622172",
"source":"tz2G2Zy3sgYCuh1EQqrx9Q62CcpSkgcLPPDt"},{
"kind":"transaction",
"fee":"1520",
"gas_limit":"10500",
"storage_limit": "300",
"amount":"300000",
"counter":"2622173",
"destination":"tz2FwBnXhuXvPAUcr1aF3uX84Z6JELxrdYxD",
"source":"tz2G2Zy3sgYCuh1EQqrx9Q62CcpSkgcLPPDt"}]
}

And also was able to verify UnsignedRaw => Hash with python code:

from pyblake2 import blake2b import binascii operation=binascii.unhexlify('008f1d96e2783258ff663f03dacfe946c026a5d194c73d1987b3da73fadea7d46b01549a0cde570a49b9200680341a6c78e87635480f940adc85a001f44eac02010238244743822921db1661fc7306c3044faac1e373906fdb5582d9454352b3b31c6c01549a0cde570a49b9200680341a6c78e87635480ff00bdd85a0018452ac02e0a712000153957451d3cc83a71e26b65ea2391a1b16713d2d00') h = blake2b(digest_size=32) h.update(b'\x03' + operation) digest = h.digest() print(binascii.hexlify(digest)) => 8541434de6c77aaa3e6a4d4e341717a5c96b14e990183fd33e8157ef53f38579

It almost seems like a bad error message. Can anyone help me figuring out what the problem with my transaction is?

P.s. in a second run with the same software I was able to generate a fully valid transaction: 007fc1ecd6a56046aaaeab78bbfa1c889eb8f502b66c720bf1ac3b40ee9ecf6d6b01549a0cde570a49b9200680341a6c78e87635480f940adc85a001f44eac02010238244743822921db1661fc7306c3044faac1e373906fdb5582d9454352b3b31c6c01549a0cde570a49b9200680341a6c78e87635480ff00bdd85a0018452ac02c09a0c000153957451d3cc83a71e26b65ea2391a1b16713d2d00231176ec0cf55e3f04d5de633c33b38a6370ad2c37fd31c4c45e12ec9f1466753c8137f5dee8105bd5cc3d4ce780f51ec01d5adb21893e75eef4b960189818a3

A third run was again deemed invalid.

Assurez-vous de révéler la clépublique une seulefoiset assurez-vous de votre comptoir correctement.

Aussi,jetez un coup d'œil à Netezos ,C # Tezos SDK. Voici unexemple de lamanière deforger,de signeret d'envoyer unetransaction:

var key = Key.FromBase58("edskS9DjUKo8ogBBU8LeU..."); var rpc = new TezosRpc("https://rpc.tzkt.io/carthagenet/"); var head = await rpc.Blocks.Head.Hash.GetAsync<string>(); var counter = await rpc.Blocks.Head.Context.Contracts[key.PubKey.Address].Counter.GetAsync<int>(); var forge = new LocalForge(); var bytes = await forge.ForgeOperationAsync(head, new TransactionContent { Source = key.PubKey.Address, Counter = ++counter, Fee = 10_000, GasLimit = 20_000, StorageLimit = 20_000, Amount = 1_000_000, Destination = "tz1KhnTgw...", }); var sig = key.Sign(new byte[] { 3 }.Concat(bytes).ToArray()); var op = bytes.Concat(sig.ToBytes()).ToArray(); var tx = await rpc.Inject.Operation.PostAsync(Hex.Convert(op));

Si celane fonctionnepasmême avec Netezos,vérifiez si votrenœud RPCest synchroniséet àjour.
Make sure you revealed public key just once and make sure you properly incement counter.

Also, take a look at Netezos, C# Tezos SDK. Here is an example of how to forge, sign and send a transaction:

var key = Key.FromBase58("edskS9DjUKo8ogBBU8LeU..."); var rpc = new TezosRpc("https://rpc.tzkt.io/carthagenet/"); var head = await rpc.Blocks.Head.Hash.GetAsync<string>(); var counter = await rpc.Blocks.Head.Context.Contracts[key.PubKey.Address].Counter.GetAsync<int>(); var forge = new LocalForge(); var bytes = await forge.ForgeOperationAsync(head, new TransactionContent { Source = key.PubKey.Address, Counter = ++counter, Fee = 10_000, GasLimit = 20_000, StorageLimit = 20_000, Amount = 1_000_000, Destination = "tz1KhnTgw...", }); var sig = key.Sign(new byte[] { 3 }.Concat(bytes).ToArray()); var op = bytes.Concat(sig.ToBytes()).ToArray(); var tx = await rpc.Inject.Operation.PostAsync(Hex.Convert(op));

If it doesn't work even with Netezos, check if your RPC node is synced and up to date.

  Based on the JSON in the original question and the status of the sender address [link](https://tezos.id/accounts/tz2G2Zy3sgYCuh1EQqrx9Q62CcpSkgcLPPDt), does counter & reveal look ok?

- Je vous suggère d'utiliser Tzkt Explorer,caril affiche desinformationsplus utiles,y compris les opérations ayant échoué dans MEMPOOL HTTPS://TZKT.IO/TZ2G2ZY3SGYCUH1EQQRX9Q62CPSKGCLPPDT/Operations.Donc,ce queje vois,c'est deux échec dans les opérations demémoire demémoires avec des comptoirs `.72`,`.73` àpartir de `12:01:49 UTC`.Dans votre question,je vois Json avec lesmêmes comptoirs,mais avec la succursale https://tzkt.io/bkixcfn1ztxnnntwsrarrswzvfc6om7radwq5mtqgx6radwq5mtqgx6radwq5mtqgx6ry4p2uhe - de `12:55:12 UTC`.Donc,je suppose que vous avezessayé d'envoyer les opérations avec les comptoirs `..72`,`.73` qui avait déjà été à Mempool.
  
  I suggest you use TzKT explorer, because it shows more useful info, including operations failed in mempool https://tzkt.io/tz2G2Zy3sgYCuh1EQqrx9Q62CcpSkgcLPPDt/operations. So, what I see is two failed in mempool operations with counters `..72`, `..73` from `12:01:49 UTC`. In your question I see JSON with the same counters BUT with the branch https://tzkt.io/BKiXcfN1ZTXnNNbTWSRArSWzVFc6om7radWq5mTqGX6rY4P2Uhe - from `12:55:12 UTC`. So, I assume that you tried to send the operations with the counters `..72`, `..73` which had already been in mempool.

- Demanièregénérale,votre JSON a l'air d'allerbien,mais lefait qu'il aiteu échoué «clones» dans lamémoire MEMPOOLpeutprovoquer l'erreur que vous avez décrite.
  
  Generally speaking, your JSON looks fine, but the fact that there were failed "clones" in the mempool may cause the error you described.

- Mercipour la réponse rapide.Latransaction dans lamémoire MEMPOOLest latransaction réussie queje parlais,maiselleestmaintenantinvalide,car la succursaleest obsolète,si cela devaitbloquer lestransactionsfutures,il seraitterminé debloquer le compteet devrait être rendu unbogue critique dans lenœud Tezos,alorsje nepensepas que ce soit la cause de l'erreur.
  
  Thanks for the quick response. The transaction in the mempool is the successfull transaction that I was referring to, however it is now invalid because the branch is outdated, if that were to block future transactions it would complete block the account and should be rendered a critical bug in the Tezos node, so I don't think that it should be the cause of the error.

- Malheureusement,je nepourraipastester la signature avec Netezos depuis queje récupère la signature d'un HSMet jene peuxpas avoir accès à la cléprivée.
  
  Unfortunately I won't be able to test signing with Netezos since I retrieve the signature from an HSM and can not get access to the private key.

Ilexiste deuxpoints de la CE valides qui correspondent à lamême signature,mais certains chaumes deblocage limitent l'utilisation à l'un de ces deuxpoints ECpour éviter lamalléabilité (=ilestfacile de convertir la signature à l'autre valeur de signatureet crée ainsi une secondetransaction valide qui aurait une carte detransaction différente sans avoir accès à la cléprivée).
