Overview

Cross-chain Gov enables DAOs to manage operations across multiple blockchains while maintaining consistent governance parameters, membership, and decisions. The system uses a home chain as the source of truth, with cross-chain proofs to synchronize state changes to foreign chains.

Motivation

Provide a coordination tool that fits the needs of regular users.

Features

• Synchronization of cross-chain governance parameters
• Non-transferable membership NFTs with voting capabilities
• DAO manifesto management across chains
• Secure proof generation and verification for cross-chain operations

Install

Build

forge build

Test

forge test

Deploy locally

Run the setup-chains.sh script:

chmod +x setup-chains.sh
./setup-chains.sh

Then deploy the factories:

forge script script/DeployFactories.s.sol --rpc-url local_optimism --broadcast

Change the factories contract addresses in script/DeployDAO.s.sol and deploy your DAO:

forge script script/DeployDAO.s.sol --rpc-url local_optimism --broadcast

Propose:

cast send <GOV_CONTRACT_ADDRESS> \
  "propose(address[],uint256[],bytes[],string)" \
  "[<GOV_CONTRACT_ADDRESS>]" \
  "[0]" \
  "[$(cast calldata "setManifesto(string)" "QmNewManifestoCID")]" \
  "New CID" \
  --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 \
  --rpc-url local_optimism

Get proposal ID:

cast call <GOV_CONTRACT_ADDRESS> "proposalIds(uint256)" 0 --rpc-url local_optimism
