erpcerpcFault-tolerant EVM RPC load balancer with reorg-aware permanent caching and auto-discovery of node providers.
Trusted by leading blockchain projects
Retries, circuit breakers, failovers, and hedged requests route to the fastest healthy upstream.
Per-provider quotas (daily or hourly) to cap usage and stay within your CU budgets to prevent runaway costs.
Persistent local cache eliminates duplicate reads while staying consistent during chain reorgs.
No need to track which provider supports which `eth_*` method - eRPC routes requests automatically.
Compare results across providers and penalize nodes that consistently disagree or return errors.
Consistent error codes, detailed messages, and integrity checks across multiple providers.
One place to track throughput (RPS), errors, and latency across all providers.
Supports basic auth, secrets, JWT, SIWE and more for secure access.
Influence how upstreams are chosen (or excluded) to serve traffic.
