You can find Cryptohopper's IP addresses in the Base config of your trading bot, under the Exchange section. The Paper trading feature must be turned off before the IP addresses are visible.

Most exchanges require you to whitelist IP addresses when you create API keys. This is a security measure called IP whitelisting — it ensures that only Cryptohopper's servers can access your exchange account through the API. Without the correct IP addresses, your exchange will block Cryptohopper's trading requests.

Click the copy button next to the IP addresses in your Base config. You can then paste all IP addresses at once into the API key settings on your crypto exchange.
