Some exchanges allow you to whitelist IP addresses when setting up API keys. If your exchange supports this, you can use Crypto Tax Calculator (CTC)’s static IP addresses to add an extra layer of security and help prevent unauthorised access to your account.

IP whitelisting is a way to limit who can use your API key. By adding one or more trusted IP addresses to a whitelist, you’re telling the exchange:

“Only allow connections from these specific locations.”

If someone tries to use your API key from any other IP address, it will be blocked, even if they have your key.

If your exchange gives you the option to whitelist IPs during API key setup, we recommend doing so. It’s not mandatory, but it improves security and ensures CTC can access your transaction data reliably.
