Project Description

Plugin on Safe, that allows a Safe wallet on chain A, to control another Safe wallet on Chain B Hyperlane SDK is used to facilitate the communication across chains.

We envision that this can open possibilities, where one Safe wallet can control multiple Safe wallets on different chains, making cross-chain control seamless from a single Safe.

How it's Made

  • Safe Plugin that allows arbitrary execution, this is done on the destination chain and enabled on the Safe wallet
  • Hyperlane Messaging API, dispatch & handle functions for cross chain messaging amongst Safe

Tech Stack:

  • Solidity
  • Typescript -> Transaction encoding / crafting
