Hello!

I’m wondering if the contract can claim unused gas from the user. I had an idea for a project, where it would inflate the gas price of a contract, and then the contract would claim the unused gas on the transaction. This is possible on other L2s like Blast.

Is this possible on Fuel?

Hey @milo could you elaborate on what do you mean by unused gas?

On other networks, like zkSync, and I’m pretty sure Fuel, there is always a max transaction cost, but the actual tx cost is usually less than that max fee. Would it be possible to inflate the “max fee” to something higher, and claim the unused gas? On [Blast](https://docs.blast.io/about-blast#gas-revenue-sharing) it is done like that, I’m wondering if that Is possible on Fuel.
