AA40 over verificationGasLimit
AA40 over verificationGasLimit is an ERC-4337 EntryPoint error that means smart account and paymaster verification together used more gas than the user operation's 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
verificationGasLimitset for the user operation is high enough to cover the gas used during smart account and paymaster verification. - If you are using the
eth_estimateUserOperationGasorpm_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 smart account and/or paymaster used more gas than expected using tools like Tenderly.
