Sending for the BNB Hack - BNB chain cookbook. Wishlist topic number 10 : Discord bot: Create and on chain webhook to listen for blockchain events and integrate it with Discord bot for real-time notifications.

Great work on setting up the Discord notification system with clear documentation and structure. The implementation is clean and easy to follow, but there are a few high-priority concerns: please address Discord webhook error handling (add retries/logging). Overall, this is a solid feature, just a few changes needed for production readiness!

[VamshiVerma]

Looks solid overall. One thing to consider: If the Discord webhook fails (for example, due to rate limits or network errors), the current implementation throws and returns a 500 error, which causes the notification to be lost. For critical alerts, could you add simple retry logic (e.g., 2–3 attempts with backoff) to reduce the risk of missing important events?

let attempts = 0;
const maxAttempts = 3;

while (attempts < maxAttempts) {
  try {
    await axios.post(DISCORD_WEBHOOK_URL, message);
    break; // Success
  } catch (err) {
    attempts++;
    if (attempts === maxAttempts) {
      logger.error("Discord webhook failed after retries", { err, message });
      throw err;
    }

    // Exponential backoff
    await new Promise(res => setTimeout(res, 500 * attempts));
  }
}

At minimum, please log the full error details so failed notifications can be diagnosed or resent. Thanks!

Nice work overall!
