Blockchain Nodes

Stackup offers nodes as a service so that you can focus on building your app instead of running infrastructure.

A node is an individual computer or device that participates in a blockchain network. To connect to the blockchain you'll need access to a node, typically via JSON-RPC. With Stackup hosted services, you can access both nodes and bundlers through a single URL and API key.

• JSON-RPC API for Nodes
