@bidzyyys What should the type of _underlying be?

[0xNeshi]

You should probably be using pub _underlying: Address, as this is an external contract, and Stylus currently has no way to represent them as part of structs.

You'll then also probably need to define a local sol interface, like in VestingWallet.
