FAQ
What is an zkSync node provider?
zkSync Node providers deliver managed crypto nodes and reliable infrastructure — giving developers instant access to the blockchain without the burden of running and maintaining their own servers. Instead of dealing with complex synchronization, heavy storage requirements, and ongoing maintenance, teams can get started immediately using high-performance hosted endpoints.
What is a zkSync RPC node?
An zkSync Node provides full blockchain access through Remote Procedure Call (RPC) endpoints. These RPC endpoints allow developers to interact with the network programmatically — sending transactions, fetching block and transaction data, querying addresses, and monitoring real-time network activity. In production environments, RPC access is the standard way most applications connect to blockchain nodes.
Should I run an zkSync node myself?
Running your own zkSync node is not necessary for most projects. Operating a node requires storage capacity, constant synchronization, security monitoring, and dedicated DevOps resources. These requirements often make self-hosted nodes costly and time consuming, particularly as your project grows.
What zkSync APIs does NOWNodes support?
NOWNodes supports multiple zkSync APIs and infrastructure options, including zkSync RPC APIs, Archive APIs and WSS (WebSocket) APIs via Mainnet. Developers can use these services to access blockchain data, stream real-time updates and build scalable Web3 applications. There is a whole node list of our service.
How can I connect to zkSync RPC endpoints?
After logging into NOWNodes and selecting a plan, navigate to the Dashboard in your account and choose the zkSync network. Then scroll down the page and click the Add a New Key button. Once your API key is generated, you can immediately start using the zkSync node through RPC endpoints.
Can I access zkSync infrastructure for free?
Yes, you can start with our START plan that gives access to shared crypto nodes with 100,000 requests for one month.
