B3 builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, recent-state debug and trace, and real-time Streams, all from one dashboard.
Query, subscribe, and stream B3 data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.
Multiple ways to access B3 data, from a single eth_call to real-time streams. Pick the interface, ship faster.
Standard JSON-RPC over HTTPS and WSS on B3 mainnet and B3 Sepolia testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
B3 is an EVM-compatible OP Stack chain settling to Base, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode B3 endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL.
Point your existing Ethereum codebase at a Quicknode B3 endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call, eth_getLogs, eth_sendRawTransaction और eth_subscribe सभी ठीक उसी तरह व्यवहार करते हैं जैसे वे करते हैं Ethereum .
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode B3 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 B3 workload. Clone, customize, and ship.
Full reference for every B3 JSON-RPC method, WebSocket subscription, and the debug and trace namespaces. Code examples for @quicknode/sdk, ethers.js, web3.js, and viem.
Indexes token transfers on an EVM chain using Quicknode Streams and delivers them to your own datastore and API. Works unchanged on B3.
From your first B3 endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your B3 endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated B3 infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.

The Ethereum toolchain you already know works unchanged on B3. Deploy contracts, manage endpoints, and ship from one Quicknode account.
Backfill and real-time B3 blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
इवेंट-आधारित अलर्ट, जिनकी डिलीवरी की गारंटी है। विशिष्ट पतों, इवेंट प्रकारों या ऑनचेन स्थितियों के लिए सदस्यता लें।
Trace transactions and inspect execution with the debug namespace, including debug_traceTransaction and debug_traceBlockByNumber, for deep analysis and reliable indexing.
Query B3's OP Stack rollup data with optimism_syncStatus and optimism_outputAtBlock. Read output roots, sync status, and L1 origin directly from the OP-Node.
Subscribe to new B3 blocks and logs over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.

"एक ट्रेडिंग प्लेटफॉर्म के लिए जहां हर मिलीसेकंड मायने रखता है, Quicknode समर्पित gRPC बुनियादी ढांचा बेजोड़ साबित हुआ। निर्बाध समर्थन और निरंतर चलने वाले प्रदर्शन के साथ, हम पहले दिन से ही आत्मविश्वासपूर्वक विस्तार करने के लिए तैयार हैं।"जोसेफ मर्फी, सीईओ @ रिदम
