PIP-34: Paloma Mainnet Messenger Support for Polygon Mainnet

PIP Name: PIP-34 Paloma Mainnet Messenger Support for Polygon Mainnet

Status: Proposed

Author(s): @LARRY

Type: EVM Proposal

Discussions-to: PIP-34: Paloma Mainnet Messenger Support for Polygon Mainnet

Created: 07/04/2023

Simple Summary

Activate controls via Paloma’s Compass-EVM deployment to Polygon mainnet. Direct the pigeons to initiate valset updates on Polygon mainnet from the Paloma Messenger Mainnet to launch the newest Paloma bots for executing remote control and liquidity management! Paloma pigeons will now control custody and liquidity on Polygon.


We will be reactivating controls to Polygon, this time from Paloma’s mainnet. This effort will allow the current Paloma validators to add or reconfirm the endpoints for chains that we believe will have liquidity and demand for secure cross-chain messaging. Our proposal for the governance vote is as follows:


Paloma is meant to monitor and deliver messages across multiple blockchains that host the most liquidity transactions. The Polygon chain hosts Quickswap & Uniswap AMM and Paloma’s validators aim to land their flock of pigeons to monitor and secure transactions on MATIC.

Specification Overview

Pigeons will need to update their .pigeon/config.yaml with the details for the Polygon Mainnet and Pigeons will need to ensure that they have 0.05 MATIC available on their MATIC wallets.

Technical Specification

  1. We will run the governance command to propose governance for the new EVM chain using the block height 44742754 and at block hash 0x1135676caf97f01afa87e736294d28d1a6d5d9966cae6112ae66785503ee83c4 from Polygonscan at Polygon Blocks #44742754 | PolygonScan
  2. The chainID for Polygon is 137.

  1. Pigeons will also have to update their ~/.pigeon/config.yaml file to add the new EVM-chain, Polygon. Pigeons will need to secure RPC endpoints for Polygon.
  chain-id: 137
  base-rpc-url: ${MATIC_RPC_URL}
  keyring-pass-env-name: MATIC_PASSWORD
  signing-key: ${MATIC_SIGNING_KEY}
  keyring-dir: ~/.pigeon/keys/evm/matic-main
  gas-adjustment: 1
  tx-type: 0

Pigeons query the MATIC chain and query for the submitted block height and block hash sent by Paloma and compare them to confirm they are on the right chain for Pigeon. If someone misconfigured their files, it would throw an error that the block height and hash are not matched.

  1. Pigeons will need to set up up their MATIC Chain EVM Keys. Don’t forget your passwords!
pigeon evm keys generate-new ~/.pigeon/keys/evm/matic-main

or import existing you existing Polygon evm private keys

pigeon evm keys import ~/.pigeon/keys/evm/matic-main


With the success of Paloma’s arbitrary logic calls on Ethereum and BNB Mainnets, Paloma aims to land on Polygon to take advantage of the control of remote liquidity on Polygon’s various DEXes including Curve, Quickswap & Uniswap.

Validator happiness is crucial to a successful Paloma Chain and this will now be the first step towards ensuring that Paloma validators will be rewarded for delivering messages on behalf of developers and users on Polygon.
