Request to Extend simulateContract Functionality to Include Event Emissions

[alessandroaw]

Hello,

I frequently use the simulateContract method in Viem for simulating contract executions, which currently provides either a revert reason or the contract's return value upon simulation. This functionality is invaluable; however, it is limited when dealing with write operations that do not return values but instead emit events (which often happened to save gas).

Typically, to capture these event emissions, I switch to using the Alchemy Simulation API. While effective, this workaround is not ideal—it requires using Alchemy's RPC and adjusting the API URL for each supported network.

Would it be possible to enhance the simulateContract method to include event emissions in the simulation results? This enhancement would not only streamline development workflows but also eliminate the need for external API dependencies.

Relevant documentation can be found here:

• Viem simulateContract documentation
• Alchemy simulateExecution reference

Looking forward to your thoughts on this potential improvement.

Thank you for considering this enhancement.
