Smartphone-Based Sensing API

We develop and deploy custom APIs and SDKs that abstract smartphone sensors (GPS, camera, mic, accelerometer) for building scalable mobile DePIN data collection applications with built-in, standardized on-chain attestation.

overview
RELIABLE FOUNDATION

Blockchain Infrastructure & Node Management

Enterprise-grade node infrastructure with 99.9% uptime SLA, multi-cloud redundancy, and real-time monitoring.

We deploy and manage your dedicated blockchain nodes, eliminating the operational overhead of self-hosting. Our infrastructure is built for production-grade reliability across EVM, Solana, Cosmos, and other major L1/L2 networks.

  • 99.9% Uptime SLA with automated failover and multi-cloud redundancy (AWS, GCP, Bare Metal).
  • Real-time Health Monitoring & Alerts via custom dashboards for RPC latency, sync status, and error rates.
  • Secure Access Controls with private endpoints, IP whitelisting, and DDoS protection.
  • Predictable, All-Inclusive Pricing – no surprise costs for requests or data.

Focus on building your application, not maintaining infrastructure. We handle node provisioning, upgrades, security patches, and 24/7 incident response.

Our managed service includes archive node access, WebSocket support, and dedicated engineering support to ensure your dApp never misses a block or suffers from unreliable public RPCs.
