* [ ] **Transaction Idempotency:** Explain your methods for preventing duplicate transaction processing to maintain data integrity.
* [ ] **Transaction Failures:** Outline your strategy for managing transactional errors and ensuring error resilience.
  * How do you handle failures, specifically late failures for EFT and ACH?
* [ ] **Webhooks Implementation:**
  * How do you manage webhook delivery failures?
  * What security measures have you implemented for webhooks, such as HMAC signatures or IP restrictions?
  * Have you configured email notifications to be alerted about failed webhook events?
* [ ] **Wallet Balance Management:**
  * Have you set up email notifications to alert you when wallet balances become negative?
* [ ] **Production Account Limits:** Confirm your awareness and understanding of the current limits on your production account.
