Streaming Payroll Infrastructure for Next-Generation Enterprises
SafeStream transforms enterprise payroll management by enabling automated, real-time PYUSD streaming through Safe multisig wallets—making PYUSD the backbone of next-generation payroll systems.
We're building the streaming payroll infrastructure for the enterprise payroll market, leveraging PYUSD's regulatory compliance to enable second-by-second salary distributions—driving mass stablecoin adoption where it matters most: everyday business operations for next-generation payroll systems.
Traditional enterprise payroll is fundamentally broken:
- Slow & Inefficient: 2-5 business days for wire transfers, locking capital
- Expensive: 2-5% fees on international payments, eating into margins
- Opaque: No real-time visibility for employees or finance teams
- Inflexible: Fixed monthly/bi-weekly schedules don't match modern work
- Complex: Multi-currency conversions, compliance overhead, banking intermediaries
Real-time PYUSD streaming that revolutionizes payroll:
- Instant: Per-second payment flows matching actual work performed
- Efficient: Near-zero transaction fees with PYUSD on-chain
- Transparent: Complete on-chain auditability for compliance
- Flexible: Employees access earned wages anytime—no loans, no waiting
- Simple: Single stable currency with regulatory clarity

Traditional Payroll:
Month 1: Work 30 days → Wait → Get paid on day 30 → Access money
[██████████████████████████████] 30 days later
SafeStream:
Day 1: Work → Money streams → Access anytime → Withdraw instantly
[█] [█] [█] [█] ... every second
Example:
- Employee earns $120,000/year
- SafeStream calculates: 3.8 PYUSD flowing per second
- After 10 days worked: $3,287.67 available (vs. $0 with traditional)
- Employee can withdraw any amount, anytime
