Cutting blockchain costs five times with dedicated nodes
How Digital Care replaced a DeFi platform’s expensive third-party RPC provider with dedicated Arbitrum and Ethereum nodes, built and operated end to end.
Paralax is a liquidity infrastructure provider: individuals, DAOs and other protocols use it to generate yield on the Arbitrum network. Every feature depends on reading and writing blockchain data, and all of it went through an expensive third-party RPC provider. The bill grew with usage, ate directly into margins, and performance depended on someone else’s infrastructure.
Own the critical path: replace the third-party provider with dedicated blockchain nodes that are cheaper at scale, faster to respond and fully under the platform’s control.
The critical path, brought in-house.
Dedicated node fleet
Deployed blockchain nodes specifically optimized for the Arbitrum and Ethereum networks, sized for the platform’s real workload.
Kubernetes underneath
Nodes run as declarative workloads with Helm and Terraform: reproducible, recoverable and easy to scale.
Hosting and management
Digital Care operates the fleet end to end: high availability, robust security and the latest node software at all times.
Monitoring
Prometheus + Grafana across every node: sync status, latency and resource consumption always visible.
Cost engineering
Economies of scale and right-sizing brought the cost of blockchain access down five times against the third-party provider.
