FAQ
What is a Optimism node provider?
Optimism 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 Optimism RPC node?
A Optimism 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.
Do I need to run my own Optimism node?
Running your own Optimism 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 Optimism APIs does NOWNodes support?
NOWNodes supports multiple Optimism APIs and infrastructure options, including Optimism RPC APIs, Index APIs, WSS (WebSocket) APIs, and Index WSS APIs on Mainnet. Developers can use these services to access blockchain data, index and query on-chain information more efficiently, retrieve transaction and wallet details, stream real-time blockchain events, and build wallets, DeFi protocols, analytics platforms, explorers, and other scalable Web3 applications on Optimism infrastructure.
You can try the interfaces even before purchasing our API through Testnet. There is a whole node list of our service https://nownodes.io/nodes.
How do I start using a Optimism node?
After logging into NOWNodes and selecting a plan, navigate to the Dashboard in your account and choose the Optimism 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 Optimism node through RPC endpoints.
Can I get a free Optimism node?
Yes, you can start with our START plan that gives access to shared crypto nodes with 100,000 requests for one month.
