AA50 postOp reverted

The paymaster contract's postOp function reverted.

Possible solutions

  • If you are using your own paymaster contract, verify that that you have correctly implemented the postOp function (if you are using one). If you do not intent to make use of the postOp function, make sure you do not set the context parameter in the paymaster's validatePaymasterUserOp function.
  • If you are using a paymaster service like Pimlico and you see this error, reach out to them.
  • If all else fails, investigate why the postOp function reverted using tools like Tenderly.
