The development stack includes: Solidity for smart contracts, React/Next.js for frontend, Web3.js or Ethers.js for wallet integration, PostgreSQL or Firebase for user data, and zk libraries (like snarkjs or circom) for privacy-preserving proofs. Backend logic handles referral systems, multi-chain support, and reward validations. Projects often integrate snapshot voting, token gating (ERC-20/NFT), and Discord bot automation. Deploying on EVM-compatible chains ensures lower gas fees and wider wallet support. This stack empowers secure, DAO-friendly Clique-style airdrops systems.
