# What is ZKP?

**ZKPay $ZKP** is a **privacy-preserving decentralized payroll network** designed to modernize how the global workforce gets paid. Built on advanced **zero-knowledge cryptography**, ZKPay enables companies, DAOs, and global organizations to **disburse salaries securely and compliantly across borders** — without exposing sensitive employee data such as identities, amounts, or locations.

At its core, ZKPay bridges **traditional corporate payroll systems** with **Web3 financial infrastructure**, leveraging the **X402 payment protocol** to facilitate near-instant fiat-to-crypto conversions for salary disbursement. With ZKPay, employers can fund payroll in fiat currencies, while contributors receive stablecoins or other digital assets on-chain, all verified through **zkPayroll Proofs** that confirm payments were made fairly and on time — without revealing confidential details.

In short, ZKPay combines **financial compliance**, **cross-border accessibility**, and **cryptographic privacy** into a unified network — forming the world’s first **Private Global Payroll Layer** for Web3 and traditional enterprises alike.
