The Stack Arc Builders Ship On

Quicknode is a leading Arc RPC provider, serving Arc testnet over low-latency JSON-RPC from 17+ global regions with a 99.99% uptime SLA. You get private JSON-RPC and WSS endpoints, full archive data, the debug_* en trace_* namespaces, and real-time Streams and Webhooks, on a platform that handles 500B+ requests a month across 80+ chains.

Arc is an EVM-compatible layer 1 from Circle, purpose-built for stablecoin finance, with USDC as the native gas token and sub-second deterministic finality from a Tendermint-based consensus engine. Arc entered public testnet in October 2025.

Create a free Quicknode account, select Arc, and a private RPC URL is generated instantly. You get full method coverage and rate limits that scale with your plan. No credit card is required for the free tier.

An Arc node is a server that validates blocks and answers JSON-RPC requests for the Arc network. Running your own means managing sync, storage, upgrades, and archive retention. With Quicknode you connect to a managed Arc testnet endpoint with HTTPS and WSS, full archive access, and a 99.99% uptime SLA, with no infrastructure to maintain.

Quicknode supports the full Arc Ethereum JSON-RPC over HTTPS and WSS, including eth_call, eth_getLogs, eth_sendRawTransaction, en eth_subscribe, plus the debug_* namespace and the trace_* namespace such as trace_transaction en trace_block for deep transaction analysis. Real-time Streams and Webhooks complete the data stack.

Quicknode serves Arc over low-latency JSON-RPC for current-state reads, historical queries, and broadcasting. Archive coverage tracks the network as it moves from public testnet toward mainnet.

Yes. Arc is EVM compatible. Deploy Solidity contracts with Hardhat, Foundry, or Remix, and use ethers.js, web3.js, viem, and @quicknode/sdk against your Quicknode endpoint exactly as you would on Ethereum.

Quicknode supports Arc testnet (chain ID 5042002). Create a free account to get a private testnet endpoint with JSON-RPC and WSS in seconds, with no credit card required.

Quicknode serves Arc from 17+ global regions behind a 99.99% uptime SLA, with automatic failover and low-latency routing. The same infrastructure handles 500B+ requests a month across 80+ chains, so your Arc apps stay responsive under load.

Quicknode offers a free tier for Arc with no credit card required, so you can get an Arc testnet endpoint in seconds. Paid plans scale with request volume and add higher rate limits, and enterprise plans add dedicated infrastructure and a 99.99% uptime SLA.

Arc uses USDC as its native gas token, so transaction costs stay dollar-denominated. Arc is currently in public testnet; use your Quicknode Arc RPC URL and the network parameters listed in the Quicknode and Circle docs.

Use Quicknode Streams and Webhooks for backfill, real-time data, and push notifications on Arc where supported, and connect over WSS with eth_subscribe for in-app subscriptions.

Arc is built for stablecoin finance: payments and settlement, foreign exchange, capital markets, and treasury apps that want dollar-denominated fees and fast finality.
