Overview

In some environments, firewalls or other security configurations may block incoming traffic unless it originates from approved IP addresses. If your environment requires IP addresses to be approved, you'll need to add the following outbound IP addresses used by Fireblocks to send webhooks to your workspace's IP allowlist.

Fireblocks strongly recommends validating webhook signatures instead of relying solely on IP addresses. Signature validation ensures the authenticity of the notification regardless of your network configuration.

❗️

Before you begin

Please note the following:

• Only Admin-level users (Owner, Admin, and Non-Signing Admin) can add IP addresses to your workspace's IP allowlist.

How to allowlist IP addresses

1. In the Fireblocks Console, go to Settings > General > IP address allowlist and then select Manage allowlist.
2. On the IP address allowlist window, select Add IP address.
3. Complete the required fields, then select Add IP address.
