To purchase a digital collectible book on the Polygon blockchain, you need to use POL, Polygon's native cryptocurrency token. Learn more about Digital Collectibles in CryptoComics here.
There are several ways to add POL to your CryptoComics Wallet.
From the purchase page of any digital collectible book, select Purchase.
The purchasing screen will pop up. It will tell you how much POL is currently in your CryptoComics Custodial Wallet (and the approximate equivalent in USD).
If you do not have any POL in your Wallet, you can click Add Funds. This will show you the ways to add funds to your Wallet.
You can use one of the recommended POL to USD exchanges to purchase POL.
If you already own POL, you can send it to your Custodial Wallet by copying your Custodial Wallet Address, or scanning the QR code to copy the address to your device. You can then send the POL from any other Wallet to your Cryptocomics Custodial Wallet by sending the amount to the address.
NOTE: Be sure to send to the correct address to avoid irreversible loss of funds.
You can also purchase POL from the My Wallet Address card in your Dashboard. Just select Add Funds and follow the prompts.
