PIP-37: Paloma Messenger Support for BASE

PIP Name: PIP-37: Paloma Messenger Support for BASE

Status: Proposed

Author(s): @LARRY

Type: EVM Proposal

Discussions-to: PIP-37: Paloma Messenger Support for BASE

Created: 08/10/2023

Simple Summary

Activate BASE deployment of the Paloma Compass-EVM vyper contract via the Paloma validator set. Direct the Pigeons to initiate valset updates on Coinbase ETH L2 BASE from the Paloma Messenger Mainnet to launch the newest Paloma bots for executing secure, remote trades on the BASE network and the decentralized exchanges launching there.


This will be the first time that Paloma mainnet will be deployed to BASE. 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 BASE chain hosts the BaseSwap and Paloma’s validators aim to land their flock of pigeons to monitor and secure transactions on its first Ethereum L2.

Specification Overview

Pigeons will need to update their .pigeon/config.yaml with the details for the Base Mainnet and Pigeons will need to ensure that they have 0.01 ETH available on their Base wallets and 0.01 ETH in the Ethereum wallets, which are already provisioned supporting the Ethereum mainnet.

Technical Specification

  1. For the BASE blockchain, we will run the governance command to propose governance for the new EVM chain using the block height 2430000 and at block hash 0x8db2ec3713f3e1e3db3357232840b9059dcec3a73b84bf97ca29fe6c60812e37 from Base Explorer at https://basescan.org/
  2. The BASE ChainID is 8453.

  1. Pigeons will also have to update their ~/.pigeon/config.yaml file to add the new EVM-chain, information for Base.

Pigeons query the Base 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 Base EVM Keys. Don’t forget your passwords!

Wallet Funding Requirement

BASE-MAIN: This wallet will require 0.001 ETH for funding. Volume will provide 0.01 BASE-ETH to all Paloma Validators on their accounts to help them get ready for BASE deployment of Compass-EVM . Paloma Foundation will refund payments daily based on balances spent from Paloma main chain use.


The newly launched Coinbase network, Base, has untapped potential for automation of trades. We look forward to bring Paloma to Base mainnets from the Paloma messenger mainnet.
