Farcaster Social Whitelist

Description

This project is intended to allow a creator on Farcaster to cast about an upcoming NFT mint, and reward any follower who likes it with whitelist for the mint.

How it works

• Creator casts about an upcoming NFT mint
• Cast hash is recorded and stored in a javascript function which is stored and deployed onchain.
• Creator deploys a modified ERC721 contract of type FarcasterRestrictedNft which has the .js source code written to storage.
• When the time comes to mint, a follower calls the whitelistMint function, the contract calls the Chainlink function to verify the msg.sender has liked the contract.

Snippits

• Modified ERC721 to integrate Chainlink functions

• Modified whitelist mint function which calls Chainlink function
