PRIVACY-PRESERVING PAYROLL

Global payroll without oversharing.

ZKPay blends x402 Payment APIs with zero-knowledge payroll proofs so teams can disburse salaries across borders while keeping amounts, counterparties, and internal policies private—yet verifiable.

WHAT IS

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.

TECHNOLOGY

Technology Behind ZKPay

ZKPay’s technological foundation combines zero-knowledge proofs, smart contract automation, and multi-layer financial bridging to achieve privacy, compliance, and scalability.

Zero-Knowledge Payroll Proofs (zkPayroll Proofs)

Each payroll transaction batch is encoded into a proof that validates payment fairness, timing, and total consistency — without exposing individual employee details. This ensures transparency for auditors while preserving privacy for recipients.

  • Batch-level fairness, timing, and totals proofs
  • Auditable without revealing individual pay stubs

X402 Bridge Layer

A high-speed payment bridge that converts fiat inflows into stablecoin outflows in seconds, enabling compliant cross-border settlements. This layer supports integration with multiple regulated on/off-ramp providers for smooth liquidity flow between banks and blockchain.

  • Seconds-level fiat→stablecoin conversion
  • Pluggable, regulated on/off-ramps

zk-KYC Compliance Modules

Optional zero-knowledge identity verification plugins for jurisdictions requiring auditability. Regulators or enterprises can confirm compliance status without accessing user data.

  • Selective disclosure for compliance checks
  • Proofs of status without identity leakage

HR Integration SDK

A developer-friendly toolkit that embeds ZKPay’s infrastructure into existing HR software, payroll tools, or DAO dashboards—supporting APIs for automated payouts, zkProof verification, and multi-chain operations.

  • REST/JS client helpers for payouts & proofs
  • Drop-in widgets for approval & receipts

Multi-Chain Deployment Architecture

EVM-compatible and initially deployed on Ethereum L2s for low fees and scalability—expanding cross-chain to Base, Polygon, and zkSync.

Ethereum Base Polygon zkSync

Encryption & Security Layer

All transactional metadata—identities, salary amounts, timestamps—is encrypted with zk-SNARK-based privacy layers, ensuring even validators cannot correlate payments to individuals.

  • End-to-end encrypted metadata vault
  • Anti-correlation design for recipients & batches
OUR VISION

Building the Invisible Payroll Network

The vision of ZKPay is to create a world where anyone can work and get paid privately, anywhere, anytime — regardless of geography, banking status, or local currency restrictions.

In today’s economy, millions of people work remotely for international employers. Yet global payroll remains complex, slow, and privacy-invasive. ZKPay envisions a future where salaries flow as freely as information — borderless, compliant, and confidential by design.

Through the power of zero-knowledge proofs, ZKPay aims to become the invisible payroll layer beneath the modern digital economy — a trustless, transparent, yet privacy-first infrastructure that empowers both employers and workers to transact securely, without intermediaries or exposure.

ROADMAP

ZKPay Roadmap

Phase 1 — Foundation of Privacy

Objective: Build the cryptographic and structural backbone of the ZKPay network.

  • Research & development of zkPayroll Proofs
  • Design of X402 Bridge Layer architecture
  • Smart contract audit framework & testnet deployment
  • Prototype payroll demo for multi-wallet salary disbursement
  • Strategic partnerships with HR tech and payment providers
  • Launch of official website & ZKPay documentation hub

Outcome: A fully functional testnet showcasing privacy-preserving salary payments powered by zero-knowledge proofs.

Phase 2 — Integration & Expansion

Objective: Enable real-world integration and prepare the network for enterprise adoption.

  • Launch of ZKPay SDK for HR & payroll platforms
  • Integration with Deel, Remote, BambooHR, and DAO tooling
  • Rollout of zk-KYC Compliance Modules for selective jurisdictions
  • Partnership onboarding with on/off-ramp providers via X402 APIs
  • Expansion to multiple EVM-compatible chains (Ethereum L2, Base, Polygon)
  • Community & ecosystem developer grants to build ZKPay integrations

Outcome: Enterprises and DAOs can integrate ZKPay directly into their payroll stacks—achieving borderless, compliant, and private salary infrastructure.

Phase 3 — Mainnet & Governance

Objective: Decentralize governance, strengthen liquidity, and launch the mainnet.

  • ZKPay Mainnet Launch with cross-border stablecoin settlements
  • Introduction of ZKP Token Utility for governance, staking, and gas rebates
  • Deployment of Payroll Proof Explorer — public zk verification dashboard
  • Establishment of ZKPay DAO for protocol evolution & upgrade voting
  • Cross-chain interoperability with LayerZero & Axelar bridges
  • Onboard NGOs, remote enterprises, and global freelancer platforms

Outcome: ZKPay evolves into a fully operational decentralized payroll network, governed by the community and trusted by enterprises worldwide.

Phase 4 — Global Payroll Layer

Objective: Transform ZKPay into the universal private payroll standard.

  • Launch of ZKPay Global Payroll Network (GPN) supporting 100+ countries
  • Fiat settlement layer expansion through licensed financial partners
  • Integration with DAO treasuries and global workforce dApps
  • Release of ZKPay Card (crypto-to-fiat payroll debit integration)
  • Continuous upgrades to zkPayroll Proofs and compliance layers
  • Begin development of AI-driven payroll analytics (privacy-respecting insights)
