How to use the bundler

ERC-4337 bundlers are relayers that bundle user operations into transactions and submit them to the blockchain. You can interact with bundlers using standard JSON-RPC requests.

To get access to the bundler, you need to use your Pimlico API key. Create one here if you don't have one. Using the API key, you can make the following JSON-RPC requests to the bundler:

• eth_sendUserOperation
• eth_estimateUserOperationGas
• eth_getUserOperationReceipt
• eth_getUserOperationByHash
• eth_supportedEntryPoints
• pimlico_getUserOperationGasPrice
• pimlico_getUserOperationStatus

If you would like an end-to-end example of how to use the bundler, please refer to tutorial 1 of the permissionless.js documentation.
