APIBundlerBundler API Endpoints

eth_getUserOperationReceipt

Get the UserOperationReceipt based on the userOpHash.

Limitations

This method retrieves and decodes userOperations from the logs of mined transactions by querying the node. If you attempt to fetch a receipt for a transaction from a distant past block, the request may be rejected by the node due to limitations on the block range size it can process.

The default range we support is 150 blocks, however the following networks have an unlimited range.

  • Ethereum
  • Polygon
  • Base
  • Optimism
  • Worldchain
  • Arbitrum
