Lasso Logo Lasso RPC

Smart RPC aggregation for consumer grade blockchain apps.

46 live RPC endpoints
46 node providers
3 configurable routing strategies

Lasso wrangles your node infrastructure and turns it into a fast, performant, reliable, and deeply configurable RPC layer. No SDKs, no downtime, just better RPC endpoints.

Intelligent Routing

Tune your RPC infra for your application's needs

Different apps require different performance characteristics from their RPC endpoints. Optimize for speed, cost, sync, throughput, or whatever matters most to you. Express those preferences through RPC endpoint slugs.

client_setup.ts
import { createPublicClient, http, webSocket } from 'viem';
// Distribute load across providers
const client = createPublicClient({
chain: mainnet,
transport: http("https://lasso.sh/rpc/eth")
});
// Distribute load across providers (WebSocket)
const clientWs = createPublicClient({
chain: mainnet,
transport: webSocket("wss://lasso.sh/ws/rpc/eth")
});

Resilience & Scale

Don't let infrastructure failures impact your users.

Lasso gives you layers of infra backups and intelligently manages them so your app doesn't have to.

Zero-Downtime Failover

Intelligent routing automatically switches between providers and protocols (HTTP/WS) to bypass outages and latency spikes.

Fault Isolated

Chains and providers run in isolated supervision trees. Failures are contained and never cascade.

Massive Concurrency

100k+ parallel routing connections enabled by the BEAM VM

Real-time Health Monitoring

Continuously tracks latency, errors, and sync status per provider, view live status in the dashboard.
