When creating API keys on the Kraken platform, on the **Add API key** page, set the **Nonce window** field to `10000000000` (one followed by ten zeros).

To avoid typos when entering this value, you can copy it above and paste it into the form as follows:

This is required for proper handling of time variables (nanoseconds in this case).
