Connect to BNB Smart Chain Mainnet and every active Testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete BNB Smart Chain data stack, managed from a single Quicknode dashboard.
BNB Smart Chain builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, full archive with debug and trace, MEV protection, and real-time Streams, all from one dashboard.
Query, subscribe, and stream BNB Smart Chain data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.
Land transactions and protect swaps on the same Quicknode account. The Ethereum toolchain you already know works unchanged on chain ID 56.
Six ways to access BNB Smart Chain 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 Mainnet and 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 BSC archive nodes for indexing, simulation, and trading forensics.
Backfill and real-time BSC blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
Event-driven alerts with guaranteed delivery, retries, and built-in reorg handling. Subscribe to specific addresses, contract events, or onchain conditions and react in real time.
Add wallet risk scores, OFAC address checks, stablecoin balances, and block timestamp lookups to your BSC endpoint with Marketplace add-ons.
Smart Transactions and reliable broadcasting land transactions during congestion, with mempool visibility and resubmission handled.

Trailing 24-hour P95 BNB Smart Chain 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.
View full benchmarkBNB Smart Chain is fully EVM compatible, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode BSC endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL and chain ID 56.
Point your existing Ethereum codebase at a Quicknode BSC 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 BSCimport { createPublicClient, http } from "viem";const client = createPublicClient({chain: { id: 56, name: "BNB Smart Chain" },transport: http(QUICKNODE_BSC_URL)});const block = await client.getBlockNumber();// Same methods, same SDK. Just chain ID 56.
BNB Smart Chain is one of the most MEV-active networks in crypto. Quicknode MEV Protection shields your swaps and high-value transactions, with no code changes.
Transactions route through a private relay instead of the public mempool, invisible to searchers and mempool explorers until they are included in a block.
Included on every Standard Plan BSC endpoint. Same contract logic, identical onchain results, no SDK changes.
Custom routing, execution guarantees, and MEV rebate programs for enterprise teams.
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode BSC 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 BSC workload. Clone, customize, and ship.
Full reference for every BSC JSON-RPC method, WebSocket subscription, and the debug and trace namespaces. Code examples for @quicknode/sdk, ethers.js, web3.js, and viem.
Step-by-step tutorials for building on BNB Smart Chain, with working code you can run. Deploy contracts, track BEP-20 tokens, index transfers with Streams, and stream real-time data.
Runnable sample app that connects AI agents like Claude and Cursor to EVM chains including BSC. Check balances, analyze contracts, and monitor gas prices through natural language.
The Quicknode Multi-Chain Faucet drips BNB Smart Chain Testnet tokens to your wallet, one drip per network every 12 hours. Connect MetaMask, Coinbase Wallet, Uniswap Wallet, or Phantom and pick your network.
From your first BNB Smart Chain endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your BNB Smart Chain endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated BNB Smart Chain infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.
