RPC looks like a solved problem until you depend on it in production. Notes from running Binari Nodes.
Latency is a budget
Every product has a latency budget, and RPC quietly spends it. Treat p99 as the number that matters — a fast median hides the calls that time out and break a user flow.
Failover is not optional
Nodes fall behind, forks happen, providers blip. Reliable RPC means redundancy with health-aware routing: route away from a node the instant it stops keeping up, not after it fails.
Observability you can act on
You can't fix what you can't see. We expose latency, error rates, and sync status so problems are visible before a customer reports them.
What builders actually want
- Predictable throughput they can plan around.
- Endpoints that don't require babysitting.
- Someone else running the chain.
That's the whole promise: take the undifferentiated heavy lifting off the builder's plate.
