Core Capabilities of Our ZK-Rollup Payroll System
A purpose-built, modular infrastructure that delivers confidential payroll processing with the scalability and cost-efficiency of Layer 2. We handle the complex cryptography so you can focus on your core business.
01
Zero-Knowledge Payroll Processing
Process payroll runs with complete confidentiality. Individual salaries, bonuses, and tax withholdings are kept private on-chain, visible only to the employee and authorized administrators via ZK proofs.

Modular Rollup Architecture
Deploy on your choice of EVM-compatible L1 (Ethereum, Arbitrum, Polygon) with our custom ZK-rollup stack. Isolate payroll logic from your main dApp for security and simplified compliance.

Architectural Comparison
ZK-Rollup Privacy vs. Traditional On-Chain Payroll
A technical and operational breakdown of how a custom ZK-Rollup payroll system fundamentally differs from a traditional, transparent on-chain implementation.
| Feature | Traditional On-Chain Payroll | Chainscore ZK-Rollup System |
|---|---|---|
Salary & Bonus Visibility | Publicly visible to anyone on-chain | Fully private; only visible to sender/receiver |
Regulatory Compliance Risk | High (public PII/salary data) | Low (ZK proofs validate without exposing data) |
On-Chain Gas Costs | High (per-transaction, per-payroll run) | Negligible (batched into single rollup proof) |
Time to Final Settlement | Network-dependent (mins to hours) | Sub-second (ZK-Rollup L2 finality) |
Implementation Complexity | Medium (standard smart contracts) | High (requires ZK circuit design & prover integration) |
Development Timeline | 4-8 weeks (standard dev) | 12-20 weeks (specialized ZK engineering) |
Ongoing Infrastructure | Mainnet/L2 node + indexers | ZK prover infrastructure + sequencer management |
Typical Audit Scope & Cost | $15K - $30K | $50K - $100K (circuit + contract audits) |
Total Cost of Ownership (Year 1) | $80K - $150K | $200K - $400K |
Best For | Transparent DAO treasuries, public grants | Enterprises, regulated entities, competitive startups |

STRUCTURED EXECUTION
Our Delivery Process: From Design to Deployment
We deliver production-ready ZK-Rollup payroll systems through a proven, transparent process. Each phase is designed to de-risk your project and ensure seamless integration with your existing financial infrastructure.
01
Phase 1: Architecture & Privacy Design
We conduct a deep-dive workshop to map your payroll logic and compliance requirements onto a zero-knowledge circuit architecture. This includes defining the privacy set (who can see what), selecting the optimal ZK-SNARK framework (e.g., Circom, Halo2), and finalizing the on-chain/off-chain data flow.

Phase 2: Circuit Development & Audit
Our cryptography engineers implement the custom ZK circuits that prove payroll calculations are correct without revealing sensitive salary data. We follow formal verification practices and submit the circuit logic for an independent security review before any integration.

Development Time

External Audit Mandatory

Phase 3: Smart Contract & Rollup Integration
We deploy the verifier contracts (Solidity/Vyper) to your chosen L1/L2 and build the off-chain prover service. This phase includes integrating with your existing HR/payroll APIs and implementing the sequencer and data availability layer for the rollup.

Phase 4: Staging & Compliance Testing
Your system is deployed to a staging environment mirroring production. We execute full payroll cycles with test data, validate privacy guarantees, and run compliance checks (e.g., tax withholding proofs, audit trail generation) to ensure regulatory readiness.
