How to implement RPC load balancing for blockchain apps: round-robin, latency-based and method-based routing, failover, and provider vs app-level strategies.
How compute unit pricing works in blockchain RPC — and why eth_getLogs costs more than eth_getBalance on most providers. Plus how fixed request unit pricing changes the math for DeFi teams.
How to build a reliable, production-grade eth_getLogs pipeline. Covers chunking, deduplication, reorg handling, retry logic and storage patterns for indexing blockchain events at scale.
What RPC infrastructure MEV searchers actually need: latency requirements, mempool access, Flashbots endpoint configuration, WebSocket patterns and provider selection criteria.
Build a production-grade smart contract event monitor using ethers.js WebSocket subscriptions. Covers reconnection logic, missed event recovery, multi-contract monitoring and alerting.
How to protect your blockchain RPC API keys in production. Covers environment variables, backend proxies, IP whitelisting, key rotation and what happens when a key is compromised.
Choosing the wrong RPC provider can break your dApp. Here are the 7 factors that actually matter when evaluating blockchain RPC infrastructure.
Building on more than one chain? Here's how to manage multi-chain RPC endpoints, avoid common pitfalls, and keep your infrastructure simple as you scale.
How to dramatically reduce RPC call volume in DeFi applications using Multicall3, response caching, batch requests and WebSocket subscriptions instead of polling.
How to implement RPC failover for your dApp using ethers.js FallbackProvider, health checks, circuit breakers and multi-provider strategies. Prevent downtime before it happens.
Real cost breakdown: running your own Ethereum node vs using an RPC provider. Hardware, maintenance, syncing time, and when each makes sense. Updated 2026.
WebSocket or HTTP for your RPC calls? Learn when to use each for DeFi, trading bots, and wallet apps — with real code examples. Blockchain-first guide.
What RPC infrastructure a production liquidation bot needs — latency, mempool monitoring, health factor scanning, Flashbots submission and failover patterns for DeFi protocols.
Every RPC error your dApp will encounter and exactly how to handle each one. Covers ethers.js v6 error types, retry logic, transaction failure debugging and production patterns.
What is a blockchain node and how does your application connect to one? Developer-first guide covering node types, RPC connections, and when to self-host vs use a provider.
Remote Procedure Call (RPC) explained: how it works, real examples, RPC vs REST, and why blockchain developers need reliable RPC infrastructure. Read the guide.
