overview
FULLY MANAGED

Blockchain Infrastructure

Enterprise-grade, multi-chain infrastructure with 99.9% uptime SLA for production applications.

We provide the dedicated, high-performance RPC nodes and secure infrastructure your application needs to scale. Our managed services eliminate the operational overhead of running your own nodes, allowing your team to focus on core product development.

  • Multi-Chain Support: Deploy on Ethereum, Polygon, Arbitrum, Base, and other major L1/L2 networks.
  • Guaranteed Performance: 99.9% uptime SLA with sub-second latency and high request throughput.
  • Enhanced APIs: Access historical data, real-time event streams, and debug endpoints.

Move from prototype to global scale without infrastructure bottlenecks or unexpected downtime.

Security is foundational. Our nodes run in isolated, secure environments with DDoS protection, private networking, and regular security audits. We handle upgrades, monitoring, and disaster recovery so you get a production-ready endpoint from day one.

STRUCTURED, ZERO-DOWNTIME APPROACH

Our 4-Phase Migration Process

A proven, step-by-step methodology to upgrade your payroll system with zero disruption to your operations or employee payouts.

01

Phase 1: Discovery & Audit

We conduct a comprehensive audit of your existing payroll logic, tokenomics, and user permissions. This includes a security review of the legacy contract and mapping all state variables for a clean migration path.

Technical & Process Questions

Smart Contract Payroll Migration FAQs

Get clear answers on timelines, security, and process for migrating your on-chain payroll system. Based on 30+ successful migrations for DAOs and Web3 companies.

A standard migration from an older payroll system (like Sablier V1 or a custom solution) to a modern, gas-optimized contract takes 2-4 weeks. This includes audit, testing on testnet, and mainnet deployment. Complex migrations with multi-token support or custom vesting logic may extend to 6 weeks. We provide a detailed project plan within 3 business days of scoping.
