Why eth_getLogs returns block range and result-count errors across RPC providers, and how to query thousands of blocks reliably with adaptive chunking.
How to read the Ethereum mempool: stream pending transactions over eth_subscribe, fetch full tx bodies, decode them, and why a co-located node sees more, sooner.
How HTTP, WebSocket, and IPC transports compare for Ethereum RPC latency, with a benchmark you can run, and when sub-millisecond IPC actually matters.
