Harden Web3 backends, event indexers, and RPC clients against rate limits, reconnect gaps, duplicate delivery, and chain reorgs.
Make Web3 backends resilient against real-world node infrastructure failures. Implements idempotent cursor management, provider fallback cascades, and deep reorganization recovery.
Provider fallback strategy with health checks and exponential backoff jitter
Idempotent event processing schema tracking txHash + logIndex + blockHash
Reorganization handler detecting removed logs and rolling back state cleanly
Automated reliability test suite simulating node timeouts and dropped connections
Examines client transports (HTTP/WS), polling vs subscription models, log filter ranges, and cursor storage.
Separates transient transport errors (429/timeouts) from permanent EVM reverts, applying specialized retry rules.
Configures redundant provider endpoints with active health checks and randomized exponential backoff.
Constructs durable event identity keys (chain + blockHash + txHash + logIndex) to guarantee exactly-once processing.
Builds backfill routines that detect block reorganization forks and reconcile state against confirmed blocks.
