EVM RPC Benchmark Methodology: Block Lag, eth_getLogs and eth_call

A practical framework for comparing EVM providers using freshness, complex reads, reliability and tail latency.

Freshness baseline

Compare block number and block hash across independent endpoints. Report lag separately from response time.

Representative methods

Benchmark eth_chainId, eth_blockNumber, eth_call, eth_getLogs and receipt reads. Use bounded log ranges to avoid unfair provider limits.

Reliability

Measure HTTP errors, JSON-RPC errors, timeouts and inconsistent results. Retry behavior must be documented rather than hidden.

Reporting

Publish raw JSON, summary CSV and methodology. Redact URL paths containing API keys.
