No, you shouldn't use the same API keys for Cryptohopper and other platforms. For most crypto exchanges on Cryptohopper, IP whitelisting is required. This means your API key will only work from Cryptohopper's servers, so using the same key on another platform would result in errors.

Even if your exchange doesn't require IP whitelisting, using the same API keys across multiple platforms is strongly discouraged. When multiple platforms share the same API key, it becomes difficult to see which platform performed a specific trade or action on your exchange. Create a separate API key for each platform you use.
