To mint NFTs triggered by Duolingo streak milestones:
- Create an NMKR account for NFT minting on Cardano.
- Sign up for a Zapier account if you don't have one.
- Start a new Zap in Zapier.
- Select Duolingo as the trigger app and choose 'New Streak Milestone' as the event.
- Connect your Duolingo account to Zapier.
- Set up the NMKR action in Zapier, linking it to your NMKR account.
- Configure the NFT minting parameters, using streak data for NFT metadata.
- Test and activate the Zap. This will automatically mint an NFT on Cardano each time you reach a new streak milestone on Duolingo.
