NadForm

NadForm is a decentralized, drag-and-drop form builder on Monad. Creators can author forms manually or generate them from natural language prompts using a client-side AI assistant (Vercel AI SDK). Form schemas are published directly to our Solidity smart contract. All submissions are encrypted client-side before hitting the chain, ensuring absolute privacy where only the creator and the submitter can decrypt the responses. NadForm includes custom on-chain access controls (Allowlist, Token-gated, Paid forms) and a built-in template marketplace where creators can list and sell form designs with a 10% platform royalty. Traditional builders (Google Forms, Typeform) rely on centralized backends that can suspend accounts, suffer downtime, or compromise sensitive user data. Web3 form alternatives improved wallet sign-in but kept database servers. NadForm solves this end-to-end: 1/ Data Sovereignty: No server in the middle. Forms and submissions reside immutably on Monad. 2/ Privacy at Rest: E2E client-side encryption guarantees that responses remain completely unreadable to operators or attackers. 3/ Programmable Access & Payments: Gating is enforced directly by Solidity. Creators can configure paid forms that route MON fees directly to their wallets, or token-gate entry to specific assets. Building NadForm taught us how to optimize complex on-chain storage on Monad without bloating gas fees. We mastered integrating client-side asymmetric cryptography seamlessly into standard React forms, managing keys securely in the browser. Finally, we learned that web3 UX can match web2 speed: by optimizing EVM transaction handling through standard wallets like MetaMask, we created a form-filling experience that is fast, secure, and fully decentralized.
