Dedicated RPC Endpoint

Overview

A Dedicated RPC Endpoint is a blockchain node interface reserved for one customer, application, workload, or capacity allocation rather than shared broadly across unrelated users. It is used to submit JSON-RPC calls, query chain state, and broadcast transactions. The Dedicated RPC Endpoint implementation should distinguish node acceptance, transaction broadcast, execution, confirmation, and indexed visibility where those stages apply.

The main risks include provider outage, stale node state, chain lag, quota exhaustion, exposed credentials, and hidden dependence on a single region or client implementation. The Dedicated RPC Endpoint recovery procedure should distinguish a rejected RPC call from a transaction that was broadcast but not acknowledged.

In production, teams should define ownership and apply authenticated access, network allowlists, capacity limits, regional redundancy, health checks, method restrictions, and request-level telemetry. It is different from running a private node because the infrastructure may still be managed by a provider, and different from a shared endpoint because capacity and policy are isolated.

Useful measures include RPC availability, p95 latency, block lag, error rate, throttled request rate, and failover success rate. Dedicated RPC Endpoint is closely connected to RPC Monitoring, RPC Failover, and RPC Rate Limit. For Dedicated RPC Endpoint, the client should retain chain, method, block or transaction reference, provider response, and the final on-chain observation.

Provider failover for Dedicated RPC Endpoint should not create a second transaction or replace a verified chain result with stale node data.

Testing Dedicated RPC Endpoint should include provider disagreement, reorganization or indexing delay, malformed data, and an unavailable node when relevant to the method.
