anoncast

Post anonymously to Farcaster and X using zero-knowledge proofs.

How it works

anoncast uses ZK proofs to verify you hold $ANON tokens without revealing your wallet address. This allows truly anonymous posting while preventing spam through token-gating.

Holder Requirements

• 5,000 $ANON - Post to Farcaster
• 2,000,000 $ANON - Auto-crosspost to X

Tech Stack

• Frontend: Next.js 15, React, Tailwind CSS
• Wallet: RainbowKit, wagmi
• ZK Proofs: Noir circuits for balance verification
• Farcaster: Neynar API
• Twitter/X: twitter-api-v2
