詳細はこちらConnect to Arc mainnet and every active testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Arc data stack, managed from a single Quicknode dashboard.
SOC 2 タイプ II 認証取得・ISO 27001
Arc builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, historical data, and real-time Streams, all from one dashboard.
Query, subscribe, and stream Arc 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 Arc data, from a single eth_call to real-time streams. Pick the interface, ship faster.
Standard JSON-RPC over HTTPS and WSS on Arc public testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
Full historical Arc testnet state with no pruning. Query any block, balance, or contract state from genesis over HTTPS and WSS.
Backfill and real-time Arc blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
配信保証、再送信、および組み込みの再編成処理機能を備えたイベント駆動型アラート。特定のアドレス、コントラクトイベント、またはオンチェーンの条件をサブスクライブし、リアルタイムで対応できます。
Trace transactions and inspect execution with the debug and trace namespaces, including debug_traceTransaction, debug_traceBlockByNumber, and trace_block, for deep analysis and reliable indexing.
Subscribe to new Arc blocks and logs over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.
Arc is an EVM-compatible layer 1 from Circle, so the tooling you already know works unchanged. ethers.js, web3.js, viem, Hardhat, and Foundry all hit a Quicknode Arc endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL.
Point your existing Ethereum codebase at a Quicknode Arc endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call、eth_getLogs、eth_sendRawTransaction、および eth_subscribe は、すべてEthereum での動作とまったく同じです。
// Your Ethereum code, pointed at Arcimport { createPublicClient, http } from "viem";const クライアント = createPublicClient({// Arc public testnet, gas paid in USDCtransport: http(QUICKNODE_ARC_URL)});const ブロック = await client.getBlockNumber();// Same methods, same SDK. Arc is EVM compatible.
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Arc 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 Arc workload. Clone, customize, and ship.
Full reference for every Arc 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 Arc.
Runnable sample apps and starter kits across Quicknode-supported chains, including Arc. Clone one and ship.
From your first Arc endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Arc endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Arc infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.
「Quicknode のAdmin API は、Circleにおけるインフラ管理のあり方を一変させました。これにより、エンドポイントをプログラムで完全に制御できるようになり、自動化がシームレスに行えるようになったほか、equipe の作業時間を大幅に短縮できました。」Circle エンジニアリング担当副社長、ジェームズ・フォン
