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. 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_sendCompressedUserOperation
• 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.
