# Option 1: Buy Sentry Key via the website

#### Go to <https://sentry.xai.games/> and follow the steps below.

{% hint style="warning" %}

* The recommended max quantity per transaction is 100 keys. Purchasing more than 100 keys in a single transaction will likely fail due to gas limits on Arbitrum One.
* There is no limit to the number of Keys per wallet.
* If you have a promo code, be sure to click "Add promo code", paste in the code, then click "Confirm".
* #### The price you see below is only for demo purposes - this is not a real key and not a final price.
