RPC Failover
Redundancy Tester
Simulate outages to verify your application's ability to switch to backup RPC providers without downtime.
RPC Redundancy & Failover Test
This simulation artificially blocks connection to the primary RPC to verify if your application correctly switches to defined backup providers.
RPC Failover & High Availability
Ensure 100% uptime for your dApps by configuring intelligent RPC failover. Automatically switch between providers if one goes down or becomes too slow.
Why Failover is Critical
Centralized RPC providers like Infura or Alchemy can experience downtime. If your application relies on a single provider, their outage becomes your outage. Configuring a backup provider (failover) ensures your users can still transact.
Active vs. Passive Failover
Passive: The system tries Provider A. If it errors, it retries with Provider B.
Active: The system constantly monitors multiple providers and routes traffic to the healthiest one (lowest latency, fully synced).
Frequently Asked Questions
Typically: HTTP 429 (Rate Limited), HTTP 5xx (Server Error), or connection timeouts. Advanced setups also failover if the node falls behind the network head (sync lag).
Yes. Some advanced architectures (like 'quorum' selection) query multiple providers for every request and compare the results to ensure data accuracy and prevent malicious node responses.
