FAQ

What is a Sui node provider?

A Sui node provider delivers managed blockchain infrastructure, giving developers instant access to the Sui network without the burden of deploying and maintaining their own nodes. Instead of managing synchronization, infrastructure, software updates, and ongoing maintenance, teams can connect to reliable hosted endpoints and start building immediately.

What is a Sui RPC node?

A Sui RPC node provides access to the Sui blockchain through Remote Procedure Call (RPC) endpoints. These endpoints allow developers to submit transactions, retrieve blockchain data, query on-chain objects, interact with smart contracts, and monitor network activity programmatically. Managed RPC access is the standard way for wallets, dApps, exchanges, and other Web3 applications to connect to the Sui network in production.

Should I run a Sui node myself?

Running your own Sui node is not necessary for most projects. Operating a node requires continuous synchronization, software updates, security monitoring, and dedicated infrastructure. These requirements often make self-hosted nodes costly and time-consuming, particularly as your application grows.

What Sui APIs does NOWNodes support?

NOWNodes provides Sui RPC API and gRPC API through reliable, enterprise-grade infrastructure. These services enable developers to broadcast transactions, retrieve blockchain data, and build high-performance applications using gRPC without maintaining their own Sui nodes.

How do I start using a Sui node?

After logging in to NOWNodes and selecting a plan, navigate to the Dashboard in your account and scroll down the page. There you will find the Add a New Key button. Click it to generate your API key, then use it to connect to the Sui API.

Can I access Sui infrastructure for free?

Yes. You can start with our START plan, which provides access to shared Sui infrastructure with up to 100,000 API requests per month.
