pimlico_getUserOperationStatus

Returns the user operation status and, optionally, the transaction hash that the bundler is using to bundle the user operation onchain. This method uses 50 credits from your daily balance.

info

The transaction hash returned when the result is submitted can change if the bundler resubmits the user operation inside a different transaction. For this reason, when showing the pending transaction hash to the user, it is recommended to keep calling this method in case the transaction hash changes.

Parameters

• userOpHash: (string) - The 32-byte hash of the user operation to check the status for.

Returns

An object containing the status information:

• status: (string) - The current status of the user operation. Possible values:

  Result	Response includes transaction hash	Description
  not_found	false	The operation hash is not known to the bundler or has been rejected during validation and has never entered the mempool.
  not_submitted	false	The operation hash is known to the bundler but is sitting in the mempool and has not been bundled into a transaction yet.
  submitted	true	The operation hash is known to the bundler, has been bundled into a transaction which is currently pending in the mempool.
  rejected	false	The operation hash has entered the mempool but as it was being bundled into a bundle transaction the re-simulation failed and it was never submitted.
  included	true	The operation hash is known to the bundler and has been included onchain.
  failed	true	The operation hash is known to the bundler and the transaction bundling it has been included onchain but the bundle transaction reverted.
  queued	false	The operation hash is known to the bundler but is waiting in a queue before being sent to the mempool due to its nonce being too high.

• transactionHash: (string) - The transaction hash bundling the user operation, or null if not applicable for the current status.
