Introduction to zkPay

zkPay is a non-custodial payment identity layer designed for the next generation of commerce. We allow developers to abstract away the complexity of handling multiple payment rails, subscription logic, and agent-driven transactions.

Why zkPay?

Unlike traditional payment gateways, zkPay doesn't hold funds. We create a persistent identity (user@zkpay.me) that routes payment requests to the user's preferred funding source based on rules they define.

Core Concepts

Payment Identity

A unique handle (e.g., alice@zkpay.me) that replaces card numbers and bank details. It's persistent, portable, and privacy-preserving.

Routing Engine

Logic that decides how a payment is processed. Examples: "Route transactions < $10 to my Debit Card", "Require approval for transactions > $100".
