AA40 over verificationGasLimit

The amount of gas used by the smart account and paymaster verification exceeded the verificationGasLimit set for the user operation.

Possible solutions

  • Verify that the verificationGasLimit set for the user operation is high enough to cover the gas used during smart account and paymaster verification.
  • If you are using the eth_estimateUserOperationGas or pm_sponsorUserOperation method 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 smart account and/or paymaster used more gas than expected using tools like Tenderly.
