zkSync stands out as one of the most promising Layer 2 solutions. Leveraging zk-rollups technology, zkSync offers fast, secure, and cost-effective transactions. But how do developers actually interact with zkSync’s network? The answer is zkSync RPC – your gateway for applications to communicate with the zkSync Layer 2 blockchain.
Let’s explore what zkSync RPC is, why it’s important, and why you might prefer using a professional API provider instead of running your own node.
What Is zkSync RPC?
RPC stands for Remote Procedure Call – a protocol that lets your application send requests to a blockchain node to perform actions like querying balances, sending transactions, or interacting with smart contracts.
Ethereum developers are familiar with JSON-RPC endpoints provided by services like Infura or Alchemy. zkSync, being a Layer 2 network, requires its own specialized RPC interface because it operates differently from the Ethereum mainnet. zkSync RPC understands zk-rollups, Layer 2 state, and offers methods to interact with zkSync’s faster and cheaper transaction environment.
Simply put, zkSync RPC is the API that allows your app to speak directly with the zkSync network.
Why Would You Run Your Own zkSync Node?
Running your own node means you have full control over the data, you don’t depend on third parties, and you can ensure your infrastructure is tailored to your needs.
However, this comes at a cost:
- High infrastructure and maintenance requirements.
- Constant updates to keep up with protocol changes.
- Monitoring and scaling to handle traffic spikes.
- Significant technical expertise required.
For many projects, this overhead is simply too high, especially when the main goal is to build great user experiences, not to manage infrastructure.
Why Use a NOWNodes zkSync API Instead?
Node providers offer ready-to-use zkSync RPC endpoints backed by powerful infrastructure. Here’s why you should consider them:
- Instant access – no setup or maintenance, just connect and start.
- Reliability and uptime – NOWNodes guarantee 99,95$ uptime.
- Scalability – they handle traffic spikes effortlessly.
- Automatic updates – always use the latest version of zkSync RPC.
This lets your team focus on building your app, not running servers.
How to Get Started with zkSync via NOWNodes API
- Sign up to get your API key.
- Use the provided zkSync endpoint in your code.
- Make JSON-RPC calls: check balances, send transactions, interact with contracts.
- Enjoy support, SLA, and peace of mind.
Conclusion
zkSync RPC is your gateway to the fast, cheap, and secure Layer 2 Ethereum experience. While running your own node is an option, using a professional API provider offers a simpler, cost-effective, and more reliable way to access zkSync.
