Blockchain applications depend on infrastructure to read network state, submit transactions, index history, obtain prices, store data, and monitor failures. Providers may offer RPC endpoints, managed nodes, APIs, indexers, oracles, decentralized storage, webhooks, and analytics. Architecture should reflect which functions are critical and what happens when one service becomes unavailable.
Evaluate infrastructure against real traffic
- • Coverage: Check networks, methods, regions, history, and data freshness.
- • Reliability: Measure latency, limits, errors, retries, and fallback behavior.
- • Operations: Review keys, logs, retention, alerts, support, and total cost.
Measure reliability for the actual workload
Compare supported networks and methods, geographic regions, latency, throughput, rate limits, historical and archival access, websocket behavior, data freshness, and service-level commitments. Headline request capacity means little without understanding bursts, compute units, timeouts, retries, and the traffic pattern of the application.
Plan for correctness and failure
Providers can disagree because of node lag, indexing methods, chain reorganizations, caching, or decoding. Define consistency requirements, validate important responses, monitor block height and errors, and use idempotent transaction submission. Critical systems may need fallback endpoints, but careless retries can duplicate work or hide inconsistent data.
Review security, privacy, and cost
Protect API keys with scopes, server-side storage, rotation, and usage alerts. Examine logs, retention, data residency, access controls, DDoS protection, incident history, dependency concentration, exports, and migration. Model total cost across requests, compute units, bandwidth, storage, webhooks, overages, support, and growth—not only the entry plan.
