Umbra Protocol Integration

Shawage

Stealth-address batch payroll for DAOs that protect contributor privacy.

Colosseum Frontier Hackathon 2026

The Problem

On-chain payroll is a privacy nightmare.

  • 💰 Salary Doxxing — Anyone can see exactly what every contributor earns
  • 🔍 Pattern Analysis — Regular payments to the same addresses expose org structure
  • ⚖️ Compliance Gap — No way to prove payroll happened without revealing individuals

A DAO contributor quit after their salary was doxxed on-chain.

The Solution

Umbra stealth addresses + scoped Viewing Keys. Privacy without the lawsuits.

👻

Stealth Transfers

Each employee gets a unique stealth address per pay cycle. Explorer sees 5 unrelated wallets.

🔑

Viewing Keys

Scoped, time-bound audit keys. Compliance officer sees payroll; public sees nothing.

📄

Audit Reports

Generate PDF audit reports with decrypted payroll data. Regulatory-ready on demand.
