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

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

1. Log in to your KuCoin account: Visit https://www.kucoin.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 Management page: After logging in, hover over the profile icon in the top-right corner of the page, and click on "API Management" in the drop-down menu.

3. Create a new API key: On the API Management page, click the "Create API" button in the top right corner.

4. Enter API key details: In the "Create API" window, enter a descriptive name for your API key (e.g., "My Trading Bot") and choose an API passphrase. The passphrase is used to sign your API requests and enhance security. Make sure to remember the passphrase or store it securely, as you'll need it when interacting with the KuCoin API.

5. 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". You can also enable other permissions like "General", "Trade", and "Margin Trade" as per your requirements.

6. Restrict IP access: To restrict access to the API key by specifying the IP addresses allowed to use it, toggle the "IP Restriction" switch to "On". Enter the allowed IP addresses specified on Jinca in the "IP List" field.

7. Complete the security verification: KuCoin will prompt you to complete a security verification. Depending on your account settings, you may need to provide a 2FA code from your authentication app, or complete other verification methods.

8. Confirm the creation of the API key: After successfully completing the security verification, click the "Confirm" button to create your API key.

9. Copy your API Key and Secret Key: After successfully creating the API key, you'll be presented with the API Key and Secret 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 KuCoin.
