Reliable Base Mainnet and Testnet infrastructure with Flashblocks. No complexity. Just infrastructure that scales with you.
Get a free Base RPC geo-balanced endpoint with Flashblocks. You can also deploy a Base node in the US, Europe, or Asia region for the lowest possible latency. By keeping your Base RPC traffic local, your users can experience lightning-fast interactions from anywhere.
Chainstack makes sure you get access to robust and scalable infrastructure, ready for your Base journey, in a matter of minutes.
We take away the burden of managing it so that you can instantly focus on building and exploring data on Base RPC and API.
Flashblocks feature is available for Base Mainnet and Testnet Sepolia endpoints, bringing near-instant transaction signals that improve responsiveness.
Built directly into Base, Flashblocks reduces effective confirmation time from 2 seconds to 200ms by streaming partial block updates before full block finality.
Global Base RPC Nodes provide personal, geographically diverse, and protected API endpoints you can immediately start using to interact with Base, starting at $0 per month.

Full node – Stores the latest Base state plus a rolling window of recent blocks, so it spins up quickly from fast-sync snapshots. Ideal for production dApps, wallets, relayers, and bot back-ends that only need up-to-date balances, events, and transaction submission.
Archive node – Keeps every historical state diff and trace from genesis onward, letting you ask “what did this address look like at block #12 345 678?” or replay transactions for forensic audits. Perfect for indexers, analytics dashboards, on-chain credit scoring, and back-testing strategies that demand full time-travel reads.
Flip a switch to turn any Arbitrum RPC node into an Unlimited. Select an RPS tier (25, 100, 250, 500, or 1000 requests per second) and make unlimited calls within that ceiling with zero plan quota drain or surprise overage fees.
Spin up a dedicated Base full or archive node on isolated hardware. Unlock full trace and debug APIs, insert custom plug-ins, and meet compliance or data-sovereignty requirements.

Lock down every Arbitrum RPC endpoint with enterprise-grade controls:
IP allowlists – Accept calls only from approved server or edge IPs. One mis-typed address and the request never reaches your node, blocking botnets and shadow APIs at the perimeter.
Origin rules – Enforce CORS and referrer checks to allow only traffic from your production domains to access the endpoint, preventing front-end code injection and hostile iframe drops before they occur.
JWT authentication – Issue short-lived JSON Web Tokens for scripts, back-end jobs, and mobile apps; each token carries a crypto-signed expiry, so even if it leaks it dies quickly and can’t be reused.
Set Slack or Email alerts so you’re the first to know if your Arbitrum node needs attention.
Chainstack Console performance charts – Open any Arbitrum node details page in Console to see API calls activity. Toggle between 1 h, 6 h, 12 h, 24 h, 7 d ranges; hover for exact data points; and download CSVs for deeper BI analysis.
Chainstack Status page alerts – Subscribe to the public status dashboard for instant email, Slack, or webhook notifications on planned maintenance, regional cloud incidents, or unexpected network events, keeping your team and stakeholders in sync without extra monitoring overhead.
We update and maintain Base nodes for you; no action needed. We apply every new chain version or security fix, ensuring you never experience downtime. If an update causes trouble, we automatically roll back to the last good setup. Your RPC stays fast, secure, and always online, allowing you to keep building.

Base is Coinbase’s OP-Stack layer 2 that settles to Ethereum while offering cheaper gas, a familiar EVM environment, and easy fiat on-ramps for the exchange’s 100 M+ users.
Base inherits the Ethereum JSON-RPC spec through the OP Stack, so familiar calls such as eth_blockNumber and eth_estimateGas work unchanged. Extra methods surface L2 gas metrics and deposit status when bridging from Ethereum L1. Developers simply point their HTTP or WSS client at a Base node for cheaper, faster EVM execution.
Because Base is an L2, storage requirements are smaller, yet sequencer traffic can spike; cloud bills range from US $100 to US $250 / month depending on archival depth. Add engineering time for OP-Stack upgrades and the real cost grows. It’s far more economical to grab a pay-as-you-go Base endpoint from a provider such as Chainstack.
You can point to Base’s shared OP Stack endpoint for free, though it slows down whenever traffic spikes. Chainstack’s free-usage tier delivers up to 3 million reliable Base requests before any billing kicks in.
Copy the Base endpoint shown in your Chainstack project. Drop it into your EVM wallet’s custom RPC list or update ethers.providers.JsonRpcProvider(<URL>) and you’re transacting on Base.
