This module allows an address on one chain to control an avatar on another chain using an Arbitrary Message Bridge (AMB). This enables a DAO on one chain to control assets and interact with systems like a Gnosis Safe on a different chain.
This module is intended to be used with the Gnosis Safe.
- Execute transactions initiated by an approved address on an approved chainId using an approved AMB
- On chain (A), deploy a Gnosis Safe and then enable the Bridge Module on the Gnosis Safe.
- On chain (B), call
requireToPassMessage()on the Bridge contract. - On chain (a), call
executeSignatures()on the Bridge contract.
The contracts have been developed with Solidity 0.8.0 in mind. This version of Solidity made all arithmetic checked by default, therefore eliminating the need for explicit overflow or underflow (or other arithmetic) checks.
