Hi,

I’m trying to deploy a simple the Simple Counter smart contract and call its functions.

After creating a Vault and Uploading the Contract Template successfully I call the contract template deploy endpoint which gives me a transaction ID.

I use that ID to send a CONTRACT\_CALL request at **/v1/transactions**.

I get status “SUBMITTED” but I if I look at the transaction history I can see the that it has failed.

```auto
	"status": "FAILED",
	"txHash": "",
	"subStatus": "UNKNOWN_ERROR",

```

is there a way to have more details on what exactly has went wrong?

Thanks  
Dinob

Hey @dinob,

Can you please share the failed transaction ID so we’ll be able to take a closer look?

Hi @dinob  
when sending a string, it must be a hex string. We got: ‘30fb48c8-0996-46e9-8b11-d578e8119f93’ in the One Time Address in the payload. (type=value\_error)

Please make sure the payload is correct and try it again

</div>

Hey @BetsalelKog

Thanks for your response, we’ve adjusted the payload and can confirm that we get a successful response back from Fireblocks. The below is a response from the `/v1/transactions` endpoint.

```auto
{
  "id": "03cfd4b4-3955-41b4-b768-53e9776b7772",
  "status": "SUBMITTED",
  "systemMessages": null
}

```

Unfortunately, this is where we start to face problems again. Once the above is complete, we carry out a `GET` call to the `/v1/transactions`. In the `GET` call we can see that we’ve got an error.

The first time, the status was

```auto

"status": "FAILED",
"txHash": "",
"subStatus": "INSUFFICIENT_FUNDS_FOR_FEE",

```

The second time, the status is returned as the below.

```auto

"status": "FAILED",
"txHash": "",
"subStatus": "UNKNOWN_ERROR",

```

At this point we’re unsure why this is occurring and what the steps are to resolve these errors. I am unsure on how we’re to interact with our demo counter smart contract. Any help would be appreciated. Thanks!

@msantilal The address you put is not a valid one.  
I can see this CONTRACTCALL data is to advance the nonce for this address right?  
0x9E6890662b51914ee5CDd66852132828D93779ca

If yes please enter this address here  
“destination” : {  
“type” : “ONE\_TIME\_ADDRESS”,  
“oneTimeAddress” : {  
“address” : “0x9E6890662b51914ee5CDd66852132828D93779ca”

I can certainly try that and let you know in a few minutes.

Out of curiosity, in the `oneTimeAddress` field, we’re passing through the ID of the deployedContract which is returned to us as `24abd0db-0c03-47a9-b114-f5640dcffc5e`. Where is the `0x9E6890662b51914ee5CDd66852132828D93779ca` address retrieved from?

Gave the provided one time address a try, still getting.

```auto
"status": "FAILED",
"txHash": "",

This 0x9E6890662b51914ee5CDd66852132828D93779ca is the source address of the vault.  
you can see it in the vault in the console.

Please set the address with 0x  
use 0x9E6890662b51914ee5CDd66852132828D93779ca

Have tried with `0x`. Still no change.

Could you provide an example payload on what the system is expecting?

Because you have 0 balance in the vault.

Use a fauct to get some ETH\_TEST5 and then try the payload with the 0x

Ok gotcha, so I use a faucet and request ETH on the `0x9E6890662b51914ee5CDd66852132828D93779ca` account?

Hi @msantilal , I’d like to pick it up from this comment of yours:

> [@msantilal](#):
>
> Out of curiosity, in the `oneTimeAddress` field, we’re passing through the ID of the deployedContract which is returned to us as `24abd0db-0c03-47a9-b114-f5640dcffc5e`. (…)

For this field, you need to pass the `contractAddress` (not ID) of your deployment, but it seems you don’t have a valid deployment yet. Please retry this deployment by referring to the pointers below:

- The `/v1/tokenization/templates` endpoint mentioned in one of your other posts will let you create a contract template to later reuse for deployments. I’m assuming you have successfully created the template, as per your initial post. I’m also assuming that now you are trying to deploy a contract instance of such template, to further perform a contract call.
- To deploy your template, for which you should have the template ID, please use the `/v1/tokenization/tokens` endpoint that is described in the OpenAPI spec (search for Fireblocks docs api swagger issueNewToken). This is the recommended endpoint to deploy contracts based on templates.
- **NOTE:** If you are using auto-fueling please revisit [Set Auto Fueling Property](https://developers.fireblocks.com/docs/set-auto-fueling-property) as your vault account still needs to have a gas token balance before the transaction is initiated.
- Your `CONTRACT_CALL` transaction seems mostly correct. The one time address to use, should actually be the address of your deployed contract.
- To find the address of your deployed contract, inspect the response of the “Issue New Token” request from above. If should have a metadata field with the contract address. Please see this sample return object from one of the SDKs, which documents return types and properties: [ts-sdk/docs/models/TokenLinkDto.md at master · fireblocks/ts-sdk · GitHub](https://github.com/fireblocks/ts-sdk/blob/master/docs/models/TokenLinkDto.md)

Happy to continue helping if you have questions on any of the above.
