tron.account.not.found

When trying to obtain the balance from a TRON (USDT) address that was generated with Tatum API, you may get the tron.account.not.found error code.

{
    "statusCode": 403,
    "errorCode": "tron.account.not.found",
    "message": "No such account for address: <address>"
}

The reason why you cannot find the account is because it is not activated in the blockchain.

To activate the account, you must make a transaction. Refer to the TRON documentation for details.

If there was no TRX sent (from the blockchain node that you receive this error) but you can find the account in the Explorer, it is because the account can accept TRC tokens.
