Frequently Asked Questions

What is Zksync?

zkSync Era is a type-4 zkEVM rollup that places proofs on Ethereum while offering account abstraction and native paymasters for meta-transactions.

How to get Zksync RPC endpoint?

Sign up for a free Chainstack account and open your project dashboard. In the dashboard, choose Add node, select Zksync, and provision either a dedicated node or an elastic cluster. After the node syncs, open Access & credentials and grab the RPC URL for immediate integration.

How to run a zkSync node?

Use Chainstack Global Node for shared zkSync Era infrastructure, a Dedicated Node for higher throughput, or self-host the zkSync node software. Chainstack keeps your node updated and synced.

What is zkSync RPC API?

The zkSync Era RPC API supports JSON-RPC calls to interact with zkSync nodes. You can access it through an RPC node provider like Chainstack for fast and managed connectivity.

How much does it cost to run a zkSync RPC?

Using Chainstack for zkSync RPC is a cost-efficient choice compared to self-hosting, which demands continuous DevOps effort to ensure uptime, security, and software updates.

Is zkSync RPC free?

Public zkSync Era RPC URLs exist, but they may be limited. Chainstack provides a free Developer plan so you can test a zkSync RPC endpoint with managed uptime.

How to setup a zkSync RPC?

Quickly set up zkSync Era RPC by creating a Chainstack account and deploying an endpoint. Self-hosting requires running the zkSync open-source software from the docs, which is more complex.

Notes for zkSync Era API

When communicating with a zkSync Era node, the client implements a JSON-RPC specification compatible with Ethereum, plus zkSync-specific extensions. The recommended libraries are ethers.js for JavaScript or web3.py for Python, alongside the official zksync-ethers SDK.

Uses ZK rollup technology with native account abstraction and custom fee tokens.

You can also access zkSync Era directly through the Chainstack MCP server — query live on-chain data, deploy nodes, request testnet funds from the faucet, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.
