I’m currently working with a Fireblocks sandbox account that includes multiple networks such as `BTC_TEST` and `XRP_TEST`, both functioning properly with updated balances and transfers.

However, I encounter an error when trying to create addresses for networks such as:

- `BNB_TEST`
- `ETH_TEST5`
- `ETH_TEST_HOODI`
- `ETH-AETH_RIN`
- `ETH-AETH_SEPOLIA`
- `ETH-OPT_KOV`
- `SOL_TEST`

```auto
Problem:

Each time I attempt to create an address on these networks, I receive the following error:

{
  "message": "Creating addresses for the provided asset is not supported",
  "code": 1010
}

Code:

const FireblocksSDK = require('fireblocks-sdk');
const fireblocks = new FireblocksSDK('YOUR_API_KEY');

async function createNetwork() {
  try {
    const vaultAccount = await fireblocks.createVaultAccount("Ram");
    console.log(vaultAccount);

    const vaultAsset = await fireblocks.createVaultAsset(vaultAccount.id, "BNB_TEST");
    console.log(vaultAsset);

    const address = await fireblocks.generateNewAddress(vaultAccount.id, "BNB_TEST");
    console.log(address);
    
  } catch (error) {
    console.error("Error creating network:", error);
  }
}

```

Hi Osiz,

Thanks for reaching out to us.

The error code 1010 means that “You’re trying to add an address to a blockchain which does not support more than 1 address.”

Please review our [API document](https://developers.fireblocks.com/reference/api-error-codes).
