MultiGov Overview＃

MultiGov is a multichain governance system that enables decentralized decision-making across multiple blockchain networks. Built on Wormhole messaging, it allows DAOs to manage proposals, voting, and execution from any connected chain without relying on a single hub or bridging assets. It empowers true multichain governance by aggregating voting power across chains and coordinating secure proposal execution.

Key Features＃

MultiGov expands DAO governance across blockchains, increasing participation, improving security with Wormhole messaging, and enabling unified decision-making at scale. Key features include:

  • Multichain governance: Token holders can vote and execute proposals from any supported chain.
  • Hub-and-spoke model: Proposals are created on a central hub chain and voted on from spoke chains, where governance tokens live.
  • Secure vote aggregation: Vote weights are checkpointed and verified to prevent double voting.
  • Cross-chain proposal execution: Approved proposals can be executed across multiple chains.
  • Flexible architecture: Can integrate with any Wormhole-supported blockchain.
  • Upgradeable and extensible: Supports upgrades across components while preserving vote history and system continuity.
  • Backed by Tally: Proposal creation, voting, and execution are coordinated via Tally.

How It Works＃

  1. Create proposal on hub chain: Proposals are created on the hub chain, which manages the core governance logic, including vote aggregation and execution scheduling.
  2. Vote from spoke chains: Token holders on spoke chains vote locally using SpokeVoteAggregators, with checkpoints tracking their voting power.
  3. Transmit votes via Wormhole: Votes are securely sent to the hub using VAAs, ensuring message integrity and cross-chain verification.
  4. Aggregate and finalize on hub: The hub chain receives votes from all spokes, tallies results, and finalizes the outcome once the voting period ends.
  5. Execute actions across chains: Upon approval, proposals can trigger execution on one or more chains, again using Wormhole messaging to deliver commands.

Use Cases＃

  • Cross-Chain Treasury Management

    • MultiGov: Vote on treasury actions from any supported chain.
    • Messaging: Transmit proposal execution to target chains.
    • Token Bridge: Optionally move assets.

  • Coordinated Protocol Upgrades Across Chains

    • MultiGov: Create a unified proposal to upgrade contracts across networks.
    • Messaging: Send upgrade instructions as VAAs and deliver execution payloads to target chains.

  • Progressive Decentralization for Multichain DAOs

    • MultiGov: Extend governance to new chains while preserving coordination.
    • Queries: Fetch on-chain vote weights from remote spokes.
    • Messaging: Aggregate results and execute actions via the hub.
