Connect to Base mainnet and every active testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Base data stack, managed from a single Quicknode dashboard.
Base builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, full archive with debug and trace, and real-time Streams, all from one dashboard.
Query, subscribe, and stream Base data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.
Six ways to access Base data, from a single eth_call to billions of rows of queryable history. Pick the interface, ship faster.
Standard JSON-RPC over HTTPS and WSS on Base mainnet and Base Sepolia testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
Full historical state with no pruning, plus the deep analysis namespaces. Run debug_traceTransaction and trace_block against Base archive nodes for indexing, simulation, and trading forensics.
Backfill and real-time Base blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
Ereignisgesteuerte Benachrichtigungen mit garantierter Zustellung, Wiederholungsversuchen und integrierter Reorg-Behandlung. Abonnieren Sie bestimmte Adressen, Vertragsereignisse oder On-Chain-Bedingungen und reagieren Sie in Echtzeit.
Fetch a block and all of its transaction receipts in a single call with qn_getBlockWithReceipts. Fewer round trips and faster indexing for trackers, explorers, and analytics on Base.
Subscribe to new blocks, logs, and pending transactions over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.
Trailing 24-hour P95 Base RPC response time, the slowest 5% of requests, the tail your users actually feel. Averaged across five global regions and measured against the most-cited providers in the category. Lower and flatter is better.
P95 (95th-percentile) JSON-RPC latency over the trailing 24 hours, averaged across five global regions, identical conditions across providers. The full benchmark defaults to a longer window, so its figures will differ.
Vollständigen Benchmark anzeigenBase is EVM equivalent, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode Base endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL and chain ID 8453.
Point your existing Ethereum codebase at a Quicknode Base endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call, eth_getLogs, eth_sendRawTransaction, and eth_subscribe all behave exactly as they do on Ethereum.
// Your Ethereum code, pointed at Baseimport { createPublicClient, http } from "viem";import { base } from "viem/chains";const client = createPublicClient({chain: base,transport: http(QUICKNODE_BASE_URL)});const block = await client.getBlockNumber();// Same methods, same SDK. Just chain ID 8453.
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Base RPC URL with the details on the right. Save, and MetaMask routes through your private Quicknode endpoint instead of a rate-limited public RPC.
Docs, guides, and runnable sample apps for every Base workload. Clone, customize, and ship.
Full reference for every Base JSON-RPC method, WebSocket subscription, and the debug and trace namespaces. Code examples for @quicknode/sdk, ethers.js, web3.js, and viem.
Use Base Flashblocks preconfirmations to react to transactions in roughly 200ms. Wire the Flashblocks WebSocket into your app for near-instant UX.
Runnable Base app that streams Flashblocks preconfirmations and renders sub-second transaction updates. Clone, customize, and ship.
From your first Base endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Base endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Base infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.
„Streams der Einfachheit und Benutzerfreundlichkeit von Quicknode Streams wir die Unterstützung für neue Blockchains in beispielloser Geschwindigkeit bereitstellen, sodass wir der Konkurrenz stets einen Schritt voraus sind.“Mario Baxter, Founder & CEO @ Stable Finance
