Introduction to Node API
Use Stackup's nodes to access ERC-4337 bundlers and blockchain nodes
Bundlers 🤝 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 ERC-4337 bundlers through a single URL and API key.
