Hi @tabshaikh! Neat suggestion! I see you have a draft PR open - are you still interested in pursuing this and do you need any help from the DevX team?

[supercontracts]

Hey @fainashalts, I had conversation in OP R&D channel (@tagging u in the thread there) and Mark suggested having it in a seperate repository called interop-std in optimism org. Temporarily i moved it all to this repo https://github.com/RiftLend/interop-std and have many more contracts like SuperPausable, SuperProxyAdmin. Would love greater discussion from op devx and contracts teams so that we can create this standard in a way that is generalized for every use case and so that it gets more adoption :)

Hi @supercontracts sorry for the delay in getting back to you on this! Very cool set of contracts you've put together! We've also been talking on the devX team about providing folks with more examples of multichain-enabling contracts/execution patterns. A little unsure right know what exactly that would look like but would love to include what you have when we do it. I was envisioning a set of libraries folks can import and build on top of, so its more about how to package it up for devs to make it maximally useful.

@fainashalts i am already using them in riftlend's multichain lending protocol https://github.com/RiftLend/contracts-v1
