Go to the marketplace page. You must have a Metamask wallet or any other that supports the Polygon network and there must be a Matic or WETH on the balance (if you want to place a bet).
In the right corner, find the “Connect” button and click on it.
3. Next, select the key you want to buy and click on it.
4. A window with an NFT Key will open in front of you. Click on the “BUY for” button. Confirm the transaction in your wallet and wait for the transaction to complete. After that, you can go above and click on the colored circle, then click on the “My item” tab.
Select the NFT Key and click on it or click on the inscription “Open for bids”.
2. In the Key tab that opens, click on the blue “Place a bid” button.
3. In the pop-up window, you need to enter the price you are willing to pay for the key. Enter the cost, how many days you are ready to wait for the confirmation of the bid. And click on the “Place a bid” button. Attention! In case of a bet, you need to pay in WETH, not Matic. Therefore, there must be WETH on your account.
Confirm the transaction in your wallet and wait for the transaction to complete. After that, you can go above and click on the colored circle, then click on the “My item” tab.
