A Farcaster frame that allows users to mint NFTs on solana directly to their wallets or email after recasting and liking the cast. Check out the blog for more details on how to create this frame and check out this cast to see the frame in action.
Tools used in this project are:
- Next.js: We'll use next.js as our framework for creating the frame.
- Crossmint: To mint NFTs on solana to the user's wallet address or email, we'll use crossmint.
- Neynar: We will use neynar to check whether the user has recasted and liked the cast.
