FAQ
What is an Ardor node provider?
An Ardor node provider delivers managed blockchain infrastructure, giving developers instant access to the Ardor network without the burden of deploying and maintaining their own nodes. Instead of dealing with synchronization, storage requirements, software updates, and ongoing maintenance, teams can connect to reliable hosted endpoints and start building immediately.
What is an Ardor RPC node?
An Ardor RPC node provides blockchain access through Remote Procedure Call (RPC) endpoints. These endpoints allow developers to broadcast transactions, retrieve block and transaction data, query account information, monitor network activity, and build wallets, explorers, and blockchain applications without operating their own infrastructure.
Should I run an Ardor node myself?
Running your own Ardor node is not necessary for most projects. Operating a node requires storage capacity, continuous synchronization, security monitoring, software updates, and dedicated infrastructure. These requirements often make self-hosted nodes costly and time-consuming, particularly as your application grows.
What Ardor APIs does NOWNodes support?
NOWNodes provides Ardor RPC API and Archive mode through reliable, enterprise-grade infrastructure. These services allow developers to broadcast transactions, retrieve block and transaction data, access historical blockchain records, query accounts and addresses, and build wallets, explorers, analytics platforms, and other blockchain applications without maintaining their own Ardor nodes.
You can try the interfaces even before purchasing our API through Testnet. There is a whole nodelist of our service https://nownodes.io/nodes.
How do I start using an Ardor 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 Ardor API.
Can I access Ardor infrastructure for free?
Yes. You can start with our START plan, which provides access to shared Ardor infrastructure with up to 100,000 API requests per month.
