FAQ
What is a Qtum node provider?
A Qtum node provider delivers managed blockchain infrastructure, giving developers instant access to the Qtum 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 Qtum node?
A Qtum node is software that connects to the Qtum blockchain, validates and relays network data, and provides access to on-chain information. Developers use Qtum nodes to retrieve blockchain data, broadcast transactions, interact with smart contracts, and build wallets, payment platforms, blockchain explorers, and other Web3 applications. Running a node provides direct access to the network but also requires continuous synchronization and infrastructure management.
Should I run a Qtum node myself?
Running your own Qtum 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 Qtum APIs does NOWNodes support?
NOWNodes provides Qtum RPC API, BlockBook API, WebSocket (WSS) API, BlockBook WebSocket (BlockBook WSS) API, and Archive API through reliable, enterprise-grade infrastructure. These services enable developers to broadcast transactions, retrieve both current and historical blockchain data, access indexed blockchain information, and subscribe to real-time blockchain and indexed events without maintaining their own Qtum nodes.
How do I start using a Qtum 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 Qtum API.
Can I access Qtum infrastructure for free?
Yes. You can start with our START plan, which provides access to shared Qtum infrastructure with up to 100,000 API requests per month.
