Welcome!!

You don’t need to know ZK to use ZKaptcha! Think of us as a smart contract captcha service.

QUICK LINKS

Introduction

ZKaptcha uses zero-knowledge proofs to protect smart contracts from bots and spam! We make this possible by making captchas compatible with on-chain logic. We allow users to show proof of personhood through proof of human work. Prevent bots from scalping NFT mints, farming web3 game assets, spamming content on DeSo, and gaming airdrops.

We are an early-stage startup working hard to keep improving our product and address the biggest need for anti-bot in web3. We need your input to help us navigate what the dev experience is like and where in your projects ZKaptcha can shine.
