This is a monorepo containing the front-end and contracts for Dropify.

• App: Next.js font-end application.
• Contracts: Smart contracts on Base.

Airdrop Scams on X: Social platforms, especially Twitter, are flooded with airdrop promotions, many of which are scams that distribute malicious links and exploit users.

Victimization of Users: A significant number of users fall prey to these scams, compromising their security and losing funds due to the deceptive nature of these airdrops.

Secure Airdrops?: Existing social media platforms lack a secure and reliable protocol for conducting legitimate airdrops, leaving users exposed to fraud.

On-chain Attestations with EAS: Each airdrop and claim is verified on-chain through Ethereum Attestation Service (EAS), providing transparency and trustworthiness to the process.

Sybil-proofing with Worldcoin: Dropcast ensures a secure airdrop process by leveraging Worldcoin to prevent sybil attacks, ensuring that each airdrop is distributed fairly and securely.

Cross-chain via Chainlink CCIP: Dropcast supports cross-chain airdrops using Chainlink CCIP, enabling seamless and secure transactions across different blockchain networks.
