If you have your MATIC in your wallet you can go on with the next step.
4. Press “Get Ticket”. You will be shown the total MATIC you have to pay. We did the tutorial on the Polygon Mumbai Testnet, on Mainnet the fees will be most probably a little bit higher. You will need to press “Confirm”. If the minting is not limited to one NFT per User, you will find a Slider next to the "Get Ticket"-Button, use it to mint more then one NFT at once.
5. Congratulations, you will receive your NFT within seconds. After getting the Success Notification from Metamask, you can view your NFT on OpenSea.
