NullPay - Pay Privately. Nullify the trace.

Hey PH — Ashish here, co-founder of NullPay. The idea started with a block explorer. I sent a test transaction to show a friend how fast crypto payments were. Pulled up the explorer to prove it landed. There it was — my wallet balance, every previous transfer, who I paid and when. I felt exposed. Not because I was hiding anything. Because I had never thought of my financial life as public property. That night I called Dhruv. We realized every business running payments on-chain is operating naked. Merchant balances, supplier payments, payroll — all visible to anyone with a block explorer. That is not a theoretical concern. It's the reason most companies refuse to touch blockchain payments for anything beyond speculation. We built NullPay on Aleo using zero-knowledge proofs. When you create an invoice, the smart contract hashes your address, the amount, and a cryptographic salt. Only the hash touches the chain. When someone pays, the contract verifies the hash without ever revealing who paid whom or how much. The payment is verifiable. The data is invisible. We also shipped an MCP server so AI agents can natively create and settle private invoices — from Claude, Cursor, Codex, or your group chat via OpenClaw. We are two final-year students at IIT Roorkee. Built this in two and a half months across five consecutive Aleo Buildathon waves. Won first place in four of them. Judges called it "on par with institutional partnerships." Happy to answer anything. Roast us, ask technical questions, tell us why this will or will not work. We are here for all of it.
