PIP Name: 137: Paloma Pigeon Support for Celo L2 EVM

Status: Proposed

Author(s): @birdlady

Type: EVM Proposal

Discussions-to: Governance - Paloma

Created: 05/30/2025

Abstract

Paloma is planning to bring the Gold token as celoGold to the MiniPay app on Celo to take advantage of MiniPay’s 7M user strong distribution network.

Motivation

The MiniPay app on Celo has 7M+ active wallets and is directly integrated with the popular Opera Mini Android browser. Launching a MiniApp where MiniPay users can buy and sell celoGold will help with celoGold distribution and is directly aligned with MiniPay’s use case of holding and sending stable assets. Paloma therefore wants to deploy Compass on Celo to allow the build on MiniPay.

Specification Overview

Pigeons will need to update their .pigeon/config.yaml with the details for Celo Mainnet and Pigeons will need to ensure that they have 5 CELO available on their Celo wallets.

Technical Specification

  1. For the Celo blockchain, we will run the governance command to propose governance for the new EVM chain using a current block height Block and corresponding block **hash **from the Celo Explorer at https://celoscan.io/
  2. The Celo ChainID is 42220.

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

Pigeons query the Celo 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.

  tx-type: 2
  1. Pigeons will need to set up up their Celo EVM Keys. Don’t forget your passwords!

or import existing you existing Celo EVM private keys

Wallet Funding Requirement

CELO-MAIN: This wallet will require 5 CELO for funding. Volume will provide 10 CELO to all Paloma Validators on their accounts to help them get ready for Celo deployment of Compass-EVM . Paloma Foundation will refund payments daily based on balances spent from Paloma main chain use.

Rationale

Paloma is launching celoGOLD, a gold backed token in collaboration with Celo. To support this, the Paloma Protocol proposes to add support for Celo chain where celoGOLD will be launched.
