PIP Name: PIP #50: - Deploy Upgraded Compass-EVM on Paloma Mainnet After Paloma v10.0.1 Upgrade

Type: EVM Proposal

Created: 11/29/2023
Simple Summary
The Compass-EVM for Gravity Bridge functionality requires that all events observed by Pigeons contain an event nonce, that is continuously increased with every event emitted by the contract. Currently gravity events emitted from the contract have the following signature:
SendToPalomaEvent(address,address,string,uint256)BatchSendEvent(address,uint256)
However, this is not enough to ensure that each batch is once. This upgrade will require a new deployment of the Compass-EVM contract to the Paloma Messenger Mainnet. The old Compass-EVM will be abandoned by the flock and all users of Paloma will need to update their EVM smart-contracts to use the newest address for Paloma’s compass-EVM client.
Abstract
Paloma Compass-EVM is the arbitrary logic call contract that deploys to each supported EVM-chain on the Paloma network. The Compass-EVM manages arbitrary contract calls as well as bridge functionality secured by the Paloma validator set of Paloma validators. From time to time, the Compass-EVM undergoes upgrades for increased security and performance.
Motivation
Paloma is meant to monitor and deliver messages across multiple blockchains via its network of validator datacenters. We are relaunching deployment on EVM target chains with new upgrades the Pigeon relay messaging system with the new messenger mainnet that comes with features required for the Paloma bridge to be fully functional.

If the proposal passes, Compass EVM will be deployed to all existing and future supported EVM target chains.
Rationale
Compass EVM manages arbitrary contract calls as well as bridge functionality secured by the Paloma validator set. In order to send messages cross-chain securely, Compass EVM needs to be deployed. The new Compass-EVM will include new event emitters as well as new functions for blueprint ERC20 contracts that will be launched from Paloma and owned by the Paloma validator set.
