overview
RELIABLE FOUNDATION

Blockchain Infrastructure

Enterprise-grade node infrastructure with 99.9% uptime SLA for your core Web3 services.

We operate and maintain dedicated, high-performance nodes across all major networks, including Ethereum, Polygon, Solana, and Avalanche. This eliminates the operational overhead and single points of failure of self-hosting.

Deploy production-ready RPC endpoints in under 48 hours, backed by a 99.9% uptime SLA and 24/7 monitoring.

  • Guaranteed Performance: Dedicated resources ensure consistent block propagation and low-latency API responses.
  • Enhanced Security: Isolated environments, DDoS protection, and regular security audits.
  • Cost Predictability: Transparent, flat-rate pricing without surprise usage spikes.
  • Full Observability: Real-time dashboards for health, latency, and request metrics.
