Building Cost-Effective Blockchain Infrastructure with eRPC and Ponder

Frak shares how they built scalable blockchain infrastructure for their automated on-chain reward distribution platform using open-source tools:

• eRPC: A fault-tolerant EVM RPC load balancer providing intelligent routing and smart caching
• Ponder: An indexer for tracking complex marketing campaigns and real-time statistics
• SST: Infrastructure-as-code for zero-touch deployments

Their setup processes ~8 transactions per active user weekly while managing 8 master contracts and 3 active factories on Arbitrum.​ Key benefits include:

• Cost optimization through strategic use of free tiers
• High reliability via multi-provider fallbacks
• Scalable architecture that grows with needs
