overview
RELIABLE FOUNDATION

Blockchain Infrastructure for FinTechs

Enterprise-grade node infrastructure and RPC services with 99.9% uptime SLA.

We provide fully managed, multi-chain infrastructure so your team can focus on product development, not node operations. Our global network ensures sub-100ms latency and zero-downtime deployments for critical financial applications.

  • Multi-Chain RPCs: Dedicated endpoints for EVM chains (Ethereum, Polygon, Arbitrum), Solana, and Cosmos.
  • Guaranteed Performance: 99.9% uptime SLA, automatic failover, and 24/7 monitoring.
  • Security & Compliance: SOC 2 Type II compliant, dedicated VPCs, and DDoS protection.
  • Developer Experience: Seamless integration, detailed analytics dashboards, and premium support.

Core Capabilities of Our L2 Indexing API

Purpose-built for production applications requiring real-time, reliable access to on-chain data across all major Layer 2 networks.

01

Multi-Chain Data Unification

Query across Arbitrum, Optimism, Base, zkSync Era, and Polygon zkEVM with a single, unified GraphQL endpoint. Eliminate the complexity of managing separate indexers for each L2.
