TL;DR: To create an API key on Kraken, log in to your account, access Security > API settings page, generate a new API key, select API key permissions including withdrawal permission, restrict IP access to Jinca’s server, confirm the creation of the API key, and copy both the API Key and Private Key to save them on Jinca.

Creating an API key on Kraken involves generating a key with the required access levels and then using it to interact with Kraken's services. Here's a step-by-step tutorial on how to create an API key with withdrawal permissions and IP address restrictions on Kraken:

Disclaimer: Make sure to enable 2FA (Two-Factor Authentication) on your Kraken account for enhanced security.

1. Log in to your Kraken account: Visit https://www.kraken.com and log in with your email and password. If you don't have an account, you'll need to sign up for one first.

2. Access the API settings page: After logging in, click on your profile icon in the top-right corner of the page, and click on "Security" in the drop-down menu. From there, navigate to the "API" tab.

3. Create a new API key: On the API settings page, click the "Generate New Key" button.

4. Select API key permissions: Choose the permissions you want to grant to the API key by clicking on the checkboxes. To enable withdrawal permissions, make sure to check the box next to "Withdraw funds". You can also enable other permissions like "Query Funds", "Query Closed Orders & Trades", and "Modify Orders" as per your requirements.

5. Restrict IP access: To restrict access to the API key by specifying the IP address given to you on Jinca, enter the allowed IP address in the "Allowed IPs" field.

6. Confirm the creation of the API key: After selecting the appropriate permissions and adding the mandatory IP address restrictions, click the "Generate Key" button to create your API key.

7. Copy your API Key and Private Key: After successfully creating the API key, you'll be presented with the API Key and Private Key. Make sure to copy both keys and save them on Jinca, as you won't be able to see the Secret Key again.

Congratulations! You've successfully created an API key on Kraken.
