First post:
Most Web3 applications start with third-party RPC providers because it is faster, cheaper, and operationally simpler than maintaining blockchain nodes internally.
That approach works well until RPC infrastructure becomes a critical dependency.
The main trade-off is straightforward.
Third-party RPC providers offer:
- fast deployment;
- global infrastructure;
- automatic scaling;
- built-in monitoring;
- support for multiple chains;
- lower DevOps overhead.
But they also introduce:
- rate limits;
- vendor dependency;
- potential censorship or filtering;
- privacy concerns;
- unpredictable costs at scale;
- a single external failure point.
Self-hosting gives much more control, but operating reliable blockchain infrastructure is not trivial. You need redundancy, monitoring, snapshots, storage planning, failover logic, and engineers who understand node behavior.
For production systems, the most sensible architecture may be hybrid: internal nodes for critical workloads, with external RPC providers as fallback or load-balancing capacity.
The question is where the threshold sits.
At what point should a Web3 project stop relying entirely on public RPC infrastructure and start running its own nodes?
Would you base that decision on traffic volume, monthly RPC costs, privacy requirements, or business criticality?
