Connect to Cosmos Mainnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Cosmos data stack, managed from a single Quicknode dashboard.
Cosmos Hub builders need more than basic RPC. Quicknode runs the full surface: Tendermint RPC, REST, and gRPC, plus archive history and WebSocket subscriptions, all from one dashboard.
Query and subscribe to Cosmos data with low latency. From a single call to live block subscriptions, you get the right interface for the job.
The Cosmos toolchain you already know works unchanged on Quicknode. CosmJS, the gaiad CLI, and IBC tooling all point at a Quicknode endpoint.
Six ways to access Cosmos data, from a single query to gRPC and live subscriptions. Pick the interface, ship faster.
CometBFT JSON-RPC over HTTPS and WSS for blocks, transactions, and consensus state on cosmoshub-4.
Full Cosmos Hub archive from block height 5200791, the start of cosmoshub-4, with no pruning. Query historical balances, staking, and governance state over REST and Tendermint RPC.
Query bank balances, staking, distribution, and governance modules over the REST gateway.
High-performance gRPC access to every Cosmos SDK module for typed, efficient queries.
Query IBC channels, connections, and packet state, plus staking and governance modules, over the Cosmos REST gateway and gRPC to track transfers across connected zones.
Subscribe to new Cosmos Hub blocks and events over a persistent WSS connection with Tendermint subscriptions. Push updates the moment they land, with no polling.
Point CosmJS at a Quicknode Cosmos Hub endpoint and read balances, delegations, and blocks, or broadcast transactions. The same Tendermint RPC, REST, and gRPC you already use, on private low-latency infrastructure.
Point CosmJS or the gaiad CLI at a Quicknode Cosmos Hub endpoint. Modules, queries, and tooling carry over.
Tendermint RPC, the Cosmos REST gateway, and gRPC are all available on one endpoint.
// Query Cosmos Hub with CosmJSimport { StargateClient } from "@cosmjs/stargate";const client = await StargateClient.connect(QUICKNODE_COSMOS_URL);const height = await client.getHeight();const balances = await client.getAllBalances(address);// Tendermint RPC, REST, and gRPC over one endpoint.
Docs, guides, and runnable sample apps for every Cosmos workload. Clone, customize, and ship.
Full reference for the Cosmos Hub Tendermint RPC, REST (LCD), and gRPC interfaces, with query and transaction examples.
Connect to a Cosmos Hub endpoint and make your first Tendermint RPC, REST, and gRPC calls in minutes.
Runnable sample apps and starter kits across Quicknode-supported chains, including Cosmos. Clone one and ship.
From your first Cosmos endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Cosmos endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Cosmos infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.
"Relay routes cross-chain intents across dozens of networks, so every new chain we add has to be rock-solid from the first block. Quicknode's HyperEVM support gave us the performance and uptime we need to quote and settle swaps in real time, without babysitting infrastructure."Julien Genestoux, VP of Engineering @ Uneven Labs (Relay)
