Smarter Node RPC for fast and resilient blockchain apps.

Geodistributed RPC routing Automatic failover Expressive routing control

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

Free

Build and test quickly

Free public RPC endpoints with shared rate limits. For higher throughput, upgrade or self-host.

Start building

Premium Providers

Pro

Higher throughput and reliability

Public providers plus commercial RPC providers (Alchemy, QuickNode, and others) for higher throughput and broader chain coverage.

Bring Your Own Keys

BYOK

Custom 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.

Chain

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.
