Does this handle EVM precompile interactions too if the logged in user is from the EVM?

[AtelyPham]

Small nit, and if you can integrate EVM precompile alongside this that would be ideal.

I'm currently integrating the precompile into the restaking, which should be completed today.

Regarding the fee value, it refers to the transaction fee. I've noted this in the design but haven't implemented it yet, so I've added a TODO in the code.
