Simulates a UserOperation and validates the ERC-4337 rules. Note: this function will revert if the UserOperation is invalid.

​
Usage

bool simulationSuccess = userOp.simulateUserOp(ENTRYPOINT_ADDR);

​
Parameters

​
userOp

  • Type: UserOperation | PackedUserOperation
The UserOperation to simulate.

​
onEntryPoint

  • Type: address
The address of the entry point. Note: if you’re using v0.7 of ERC-4337, this should be the address of the EntryPointSimulations contract.

​
Returns

​
simulationSuccess

  • Type: bool
True if the simulation was successful, false otherwise. Note that a UserOperation might revert during validation, in which case the ERC-4337 rules will not be checked properly.
