Smarter Node RPC for fast and resilient blockchain apps.
Lasso wrangles your node infrastructure and turns it into a fast, reliable, and deeply configurable RPC layer. No SDKs, no downtime, just better endpoints and access to high performance proxy infrastructure.
How it works
01 / Choose your node infrastructure profile
Public Providers
FreeBuild and test quickly
Free public RPC endpoints with shared rate limits. For higher throughput, upgrade or self-host.
Start buildingPremium Providers
ProHigher throughput and reliability
Public providers plus commercial RPC providers (Alchemy, QuickNode, and others) for higher throughput and broader chain coverage.
Bring Your Own Keys
BYOKCustom profiles with your own provider keys
Bring your own provider keys. Lasso adds routing, failover, and observability on top of infrastructure you already manage.
02 / Express your routing
Express your desired chain + routing strategy + node infrastructure profile in the RPC endpoint. Target different URLs to fit your RPC workload the best. Optimize for latency, cost, RPC method support, and more.
Route each RPC method to its lowest-latency upstream provider

03 / Ship with more resilient node RPC
› Instant Failover
Provider down or rate-limited? Traffic reroutes to the next best provider with no request disruption.
› Adaptive Routing
Lasso learns which providers perform best with per-method granularity while getting smarter over time.
› Real-Time Health
Latency, error rates, and block sync tracked per provider, per method. Only route to healthy, synced providers.
› Expressive Strategies
Use dynamic URL slugs to control latency, cost, throughput, and more to match your app's needs.
Live Dashboard
Full visibility into your RPC layer
Realtime observability across your RPC activity, provider health, and method-level performance.
› Per-Provider Metrics
P50/P95 latency, error rates, success rates, and request volume — broken down by RPC method per provider.
› Live Routing Decisions
Watch which provider handled each method, the strategy used, and the response latency in real time.
› Circuit Breaker State
See which providers are active, in cooldown, or circuit-broken — with zero-downtime failover details.
› Per-Method Latency
Compare how each provider performs on specific methods. Spot outliers across your entire provider fleet.
› Block Sync Status
Track block heights across every provider. Instantly spot providers behind the chain tip.
› Multi-Region View
Compare provider performance from each edge region or aggregate across the full cluster.
