How to queue begintransaction?

Question

Laravel

Question on transactions:
There is a script which changes a cell. But the fact is that if, for example, I make a simultaneous request from two devices, then one request (which is the first one) is executed, and the second one is not. And it is necessary that both were executed, only in the order of the queue.
How to implement something like this. I did not find information on this issue, or maybe I just did not ask the right question.

DB::beginTransaction();

$balanceNow = Users::find(Auth::id());

if ($balanceNow < $request->sum) {
      return Response::json([
         "errors" => ["Ошибка"]
      ], 422);
}

$response = json_decode(Wallet::send($request->address, $request->sum));
//записи в базе
if ($response->desc == 'OK') {
   DB::commit();
}else{
   DB::rollBack();
}

So you need https://laravel.ru/docs/v5/queues queues, not transactions.
Transactions are needed when writing to the database, in your example you don’t understand why
