Mukutu Router

Mukutu Router is a Safe app for managing assets and interacting with smart contracts and dapps on multiple chains from one Safe account.

This app works as an intermediary between a Safe account on the origin chain and Safe apps providing an interface to an app or asset on the remote chain.

This is achieved by advertising the remote chain and a Hyperlane Interchain Account (which is an EIP-1014/CREATE2 account) as the currently connected chain and account respectively to the Safe app while also providing a Safe apps SDK interface (including an RPC provider for read calls to the remote chain). This allows us to leverage already existing user-friendly UI/UX of other Safe apps to compose the remote chain transaction. This app then intercepts the sendTransaction call, translates it to a call to the Hyperlane Interchain Account Router on the origin chain and submits it to the Safe Account for approval and execution.

NOTE: 🚧 Mukutu Router is still work in progress, check back over the next few weeks for regular updates.
