Arc mainnet is now liveGet started with RPC, Streams, and Webhooks.
建立一個endpoint已通過 SOC 2 Type II 認證 · ISO 27001
Connect to Arbitrum One mainnet and Sepolia Testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Arbitrum One data stack, managed from a single Quicknode dashboard.
Arbitrum 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 Arbitrum 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 Arbitrum 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 Arbitrum One and Sepolia testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
Trailing 24-hour P95 Arbitrum One 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.
過去 24 小時內的 P95（第 95 百分位數）JSON-RPC 延遲，取自全球五大區域的平均值，各服務供應商在相同條件下測量。完整的基準測試預設採用較長的觀察窗口，因此其數值將會有所不同。
查看完整基準測試Arbitrum is EVM equivalent, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode Arbitrum endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL and chain ID 42161.
Point your existing Ethereum codebase at a Quicknode Arbitrum endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call、eth_getLogs、eth_sendRawTransaction 以及 eth_subscribe 的運作方式，與在Ethereum 上完全相同。
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Arbitrum 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 Arbitrum workload. Clone, customize, and ship.
Full reference for every Arbitrum 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 Arbitrum, with working code you can run. Deploy contracts, track tokens and transfers, index onchain events, and stream real-time data.
The Quicknode Multi-Chain Faucet drips Arbitrum One 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 Arbitrum One endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Arbitrum One endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Arbitrum One infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.

Land transactions on the same Quicknode account. The Ethereum toolchain you already know works unchanged on chain ID 42161.
Full historical state with no pruning, plus the deep analysis namespaces. Run debug_traceTransaction and trace_block against Arbitrum archive nodes for indexing, simulation, and trading forensics.
Backfill and real-time Arbitrum blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
具備傳送保證的事件驅動式警示。可訂閱特定地址、事件類型或鏈上條件。
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 Arbitrum.
Batch queries, transaction submission, and contract interactions for HyperEVM and HyperCore historical data.
// Your Ethereum code, pointed at Arbitrumimport { createPublicClient, http } from "viem";import { arbitrum } from "viem/chains";const 客戶端 = 建立公開客戶端({chain: arbitrum,transport: http(QUICKNODE_ARBITRUM_URL)});const 區塊 = await client.getBlockNumber();// Same methods, same SDK. Just chain ID 42161.
Deploy ERC-20 tokens from a factory contract. Clone the app and ship on Arbitrum.
