 ## Transaction
 
+> Starting from version 9.6 you can safely use standard framework transactions.
+
+You definitely need to know the feature of transactions. The wallet is automatically blocked from the moment it is used until the end of the transaction. Therefore, it is necessary to use the wallet closer to the end of the transaction.
+
+Very important! Almost all wallet transactions are blocking.
+
+```php
+use Illuminate\Support\Facades\DB;
+
+DB::beginTransaction();
+$wallet->balanceInt; // now the wallet is blocked
+doingMagic(); // running for a long time.
+DB::commit(); // here will unlock the wallet
+```
+
+The point is that you need to minimize operations within transactions as much as possible. The longer the transaction, the longer the wallet lock.
+The maximum wallet blocking time is set in the configuration. The longer the transaction takes, the more likely it is to get a race for the wallet.

Starting with version 8.2, a special error has appeared that will inform you about incorrect work with the `TransactionStartException` package.
