Your dApp backend reads and writes chain state through a hosted RPC provider. How do you make that dependency reliable?
dApp RPC node reliability means treating blockchain nodes as rate-limited, sometimes lagging read replicas rather than perfect infrastructure. Production backends need retries, confirmation depth, bounded log queries, nonce coordination and their own indexed reads.

Answer
Short answer
Make a dApp backend reliable by using multiple RPC providers, timeouts, backoff, confirmation-depth rules and idempotent retry paths. Do not use raw RPC as the product database; index events and chain state you need to query repeatedly.
