#Troubleshooting Authentication with Stellar Accounts on Soroban

In [this document], the example successfully calls the increment function through [Transaction Invoker] authentication, but I want to try to authenticate using [Stellar Account]. I have made many attempts, but none of them have been successful, and I don't know where I went wrong. I would like to ask if anyone has successfully authenticated using Stellar Account, I haven't found any successful transactions on the chain 😔.

Here is the transaction I constructed:
https://horizon-futurenet.stellar.org/transactions/2c407c54556853e56e6107a100f32fd050544bb6ac839bcd3b37810c8e5c1915

The contract id is 8542841a633aafc771f07bc472b7a799fa2e82cced417356505f569daaaedc47, and the contract code is available at https://github.com/stellar/soroban-examples/tree/v0.6.0/auth.

The following are the keypairs used in the transaction:

kp0:

(it's holiday in the states so people might be slower to respond)

(or, of course, you can wait for more client side support)

nonce has to correspond to the contractID of the rootInvocation. It is stored in the ledger entry with CONTRACT_DATA key with contractID from rootInvocation and SCVal key with the following value: ScVal::Object(Some(ScObject::NonceKey(address))).

@twin glade If the data described above cannot be found in the ledger entry, should the nonce be set to 0?

twin glade
#

yes

tx looks correct overall

#

obviously, I've no idea if symbols/signatures are correct, but the structure appears right

#

does it succeed?

sharp merlin
#

I've checked the symbols and signatures many times and I think they should be correct, but this transaction fails.

twin glade
#

ah, I see. what is the contract you're trying to invoke?

sharp merlin
twin glade
#

ok, just the example one, good

#

I think I've found one issue: the signature args needs one more external array. this is a bit unfortunate and probably should be changed, but that's what we have this release

#

though let me check...

#

here is a valid ContractAuth entry in Rust:

ContractAuth {
 address_with_nonce: Some(
 AddressWithNonce {
  address: Account(
  AccountId(
   PublicKeyTypeEd25519(
   Uint256(277b79c38cd2c1795c546b1fea23e15e03c7971d4526307f08e6b9db36ae62a2),
   ),
  ),
  ),
  nonce: 0,
 },
 ),
 root_invocation: AuthorizedInvocation {
 contract_id: Hash(933fac395a8e18efb564c85b0d6e74fb6c518327a3734ec503938e4421a7a77e),
 function_name: StringM(tree_fn),
 args: ScVec(
  VecM(
  [],

 ),
 sub_invocations: VecM(

  AuthorizedInvocation {

   args: ScVec(
   VecM(

   ),
   ),
   sub_invocations: VecM(

   ),
  },
  ],
 ),
 },
 signature_args: ScVec(
 VecM(
  [
  Object(
   Some(
   Vec(
    ScVec(
    VecM(
     [
     Object(
      Some(
      Map(
       ScMap(
       VecM(
        [
        ScMapEntry {
         key: Symbol(
         StringM(public_key),
         ),
         val: Object(
         Some(
          Bytes(
          BytesM(277b79c38cd2c1795c546b1fea23e15e03c7971d4526307f08e6b9db36ae62a2),
          ),
         ),
         ),
        },
        ScMapEntry {
         key: Symbol(
         StringM(signature),
         ),
         val: Object(
         Some(
          Bytes(
          BytesM(f448dff40288fc32afa950d816128d0f5a74b3999af1b033febcb6bef9b6b57096bd51fc8f4fb3e8676bdca42c60102d365227e61299aa35e0807ecc0626a009),
          ),
         ),
         ),
        },
        ],
       ),
       ),
      ),
      ),
     ),
     ],
    ),
    ),
   ),
   ),
  ),
  ],
 ),
 ),
}
#

and we indeed need one more vec for the signature_args, sorry about the confusion

sharp merlin
#

@twin glade, thank you for your response 👍. I will patiently wait for the new release.

twin glade
#

oh, current release totally works as well

#

just wrap your signature args into one more sc vector, like I do here

#

it's just that this vector is redundant

#

so we should remove it. but for this release just use a wrapper vector and everything should hopefully work

sharp merlin
#

I understand, thank you. If I succeed in submitting, I will let you know.

twin glade
#

good luck! it would be cool if you make it work
