The actual gas cost of the user operation ended up being higher than the prefund paid by the smart account or the paymaster.
- If you encounter this error, try increasing the
verificationGasLimitset for the user operation.
- If you are using the
pm_sponsorUserOperationmethod from bundler provider like Pimlico to set user operation gas limits and the EntryPoint throws this error during submission, reach out to them.
- If all else fails, investigate why the actual gas cost ended up being higher than the prefund paid using tools like Tenderly.
