The Problem

On-chain payroll means
public salaries

Every existing Web3 payroll solution — Sablier, Request Finance, Utopia Labs — transfers visible tokens on-chain. Anyone with a block explorer can see exactly how much every employee earns.

Salary amounts visible on Etherscan
Competitors can poach employees by salary
No compliance with privacy regulations
Zero payroll confidentiality
The Solution

Hushroll encrypts
everything

Using Zama's Fully Homomorphic Encryption, every salary amount is stored as an encrypted euint64. The blockchain processes payments without ever seeing the amounts.

All salaries encrypted with FHE (euint64)
Only employees can decrypt their own pay
On-chain receipts with full privacy
Enterprise-grade multi-sig approvals
Features

Enterprise payroll, Web3 privacy

Every feature you expect from modern payroll software — rebuilt with complete financial confidentiality.

FHE-Encrypted Salaries

All payroll values are stored as encrypted euint64. Salary and payment amounts stay unreadable on-chain while remaining computable for payroll execution.

Multi-Sig Approvals

Configure 1-of-1 to N-of-M approval workflows. Every payment — even automated ones — requires consensus before execution.

Batch Processing

Process payroll for active employees in one batch flow, with pending/approved states handled through the same approval model as single requests.

Encrypted Invoices

Employees submit structured invoices with AES-encrypted metadata and attachments, while confidential invoice amounts flow through the same payroll approval model.

On-Chain Receipts

Permanent, tamper-resistant payment records with clear request and execution history. Employers can export payroll history for reporting.

Real-Time Analytics

Live analytics powered by subgraph aggregates across payroll activity, payment timelines, frequency distribution, and approval workflow health.

Departments & Managers

Organize payroll by departments, assign managers, and operate with role-aware workflows across employer, employee, approver, and manager views.

How It Works

From deposit to paycheck in 4 steps

STEP 01

Deposit & Encrypt

Deposit USDC or USDT and wrap into confidential tokens (cUSDC/cUSDT). Payroll balances become unreadable on-chain.

STEP 02

Add Employees

Onboard employees with encrypted salaries, set payment frequency, and configure solo or multi-sig approval thresholds.

STEP 03

Run Payroll or Review Invoices

Trigger batch payroll for due employees or review encrypted invoices with attachments. Both routes feed the same approval and execution model.

STEP 04

Employees Get Paid

After required approvals are met, payment amounts are transferred as encrypted tokens. Employees can decrypt their own balances and receipts.
