To purchase a digital collectible book on the Polygon blockchain, you need to use Matic, Polygon's native cryptocurrency token. Learn more about Digital Collectibles in CryptoComics here.
There are several ways to add Matic 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 Matic is currently in your CryptoComics Custodial Wallet (and the approximate equivalent of that to USD).
If you do not have any Matic 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 Matic to USD exchanges to purchase Matic, Transak or Coinbase. For more information on using Transak or Coinbase to purchase Matic, read more here.
If you already own Matic, 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 Matic 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 Matic from the My Wallet Address card in your Dashboard. Just select Buy Matic on Transak and follow the prompts.
