# Best Practices

Follow these best practices to ensure smooth operation and avoid common issues.

* **Always check balance first**: Before adding balance, check if there's already sufficient balance.
* **Error handling**: Implement proper error handling for blockchain transactions.
* **Default values**: Use reasonable default values for balance amounts (e.g., 0.05 ETH).
* **Chain ID**: Always ensure the correct chain is selected before adding balance.
* **Subscription check**: Verify if the user is subscribed before adding a balance.
