I!ROBOT

IIROBOT revolutionizes Web3 e-commerce with a double-blind privacy cashier Infrastructure-as-a-Service (IaaS). We solve the bot sniping problem via native World ID integration while balancing absolute privacy with verifiable trust. For merchants, we offer permissionless pseudonymity to launch e-shops without doxxing corporate identities. For buyers, we ensure strict data separation: our IaaS acts as a zero-knowledge bouncer, returning only a boolean verification without touching consumer data. However, to guarantee ultimate consumer protection, the actual checkout logic is powered by smart contracts. This provides complete sales transparency. Every purchase acts as an immutable on-chain receipt, allowing buyers to cryptographically prove their payments in case of any disputes.

We built HumanGate as a Next.js + React demo with Tailwind for the UI, then paired it with a lightweight Express backend and a small embeddable SDK for merchant flows. Wallet connection is handled with Wagmi/Viem and WalletConnect, while human verification is powered by World ID. On the backend, we verify proofs, generate relying-party context/signatures, and store demo merchant data in SQLite. One of the hackier but useful parts was building a separate tspapi surface so the same verification + payment flow could run both inside the main app and inside very simple static merchant pages like the grandma demo.
