Chainstack

How do I get started with Chainstack?

Create a free Chainstack account to deploy your first node. Select a project, choose a network, click Create node, and grab the auto-generated RPC URL for immediate use in Hardhat, Foundry, web3.js, ethers.js, or any SDK you prefer. Upgrade plan for more throughput and included API calls.

What blockchains and networks does Chainstack support?

Chainstack gives you reliable access to 70+ chains: Ethereum, Solana, Base, Polygon, BNB Smart Chain, and Arbitrum to newer ecosystems such as Hyperliquid, Unichain, Linea, Berachain, and Katana — across mainnets, testnets, and layer-2 rollups.

Which plan is right for me?

Developer (Free): Spin up a Global Node in seconds with 3M request units and 25 RPS — great for testing and hackathons. Growth: 20M request units, 250 RPS, Unlimited Node tiers, Trader Node, and Debug & Trace support. Pro: 80M RUs, 400 RPS, 15 nodes per project, Dedicated Nodes. Business: 200M RUs, 600 RPS, automation, and advanced support. Enterprise: 400M+ RUs, unlimited nodes, 24/7 support, and custom SLAs.

What is an RPC node provider?

A RPC node provider is a service that runs and maintains blockchain nodes for you and exposes them through Remote Procedure Call (RPC) interfaces. By connecting to the best RPC provider like Chainstack, you get instant, always-on access to reliable nodes without having to build or secure the infrastructure yourself.

Is the managed RPC node secure?

Yes. Every RPC node instance on Chainstack is isolated, encrypted in transit and at rest, and shielded by automated DDoS protection. You can also restrict access with IP whitelists, origins, and private credentials, so only your app can reach the endpoint.

What is an RPC node?

An RPC node is a full or archive blockchain node that exposes standard JSON-RPC or gRPC methods. It listens to new blocks, stores historical data, and answers calls so your application can read from or write to the chain with low-latency.

What is an RPC endpoint?

An RPC endpoint is the network address—HTTP(S) or WebSocket—where a blockchain node accepts requests. When your code sends a signed transaction or a read-only query, it hits this endpoint, which forwards the call to the blockchain client and returns the result.

What is an RPC URL?

An RPC URL is the complete address of an endpoint, including protocol, host, and unique project path or token. Point your web3 library at this URL to start building immediately.
