# Integrating MultX for Cross-Chain Governance & Treasury Management

<figure><img src="/files/FcsbbE96fNfyOfUASasO" alt=""><figcaption></figcaption></figure>

Based on the MultX protocol, it enables secure cross-chain token transfers using a multi-validator scheme. This can be leveraged for: ✅ Cross-Chain DAO Voting Execution\
✅ Secure Treasury Management\
✅ Automated Proposal-Based Fund Transfers

### 1. How MultX Works & Its Governance Application <a href="#xo2x3fsdtgyc" id="xo2x3fsdtgyc"></a>

#### MultX Protocol Flow (Simplified) <a href="#vx1mk4j9cey0" id="vx1mk4j9cey0"></a>

1. A user initiates a cross-chain transaction (sending tokens to a bridge contract).
2. 3 separate validators catch the event and independently sign it.
3. Once 2 out of 3 validators approve, the relayer executes the transaction on the destination chain.
4. The smart contract verifies signatures and processes the swap.

#### Use Case: Cross-Chain DAO Voting Execution <a href="#qrtzyig8mehu" id="qrtzyig8mehu"></a>

●     Instead of token swaps, governance votes can be transferred across chains.

●     Validators confirm votes and relay them securely.

●     Final tally is aggregated on the main governance chain.

### 2. Implementing Cross-Chain DAO Voting with MultX <a href="#a4pxqo9q38g5" id="a4pxqo9q38g5"></a>

We modify our DAO Voting Contract to work with MultX Validators.

#### 2.1 Deploy Cross-Chain Voting Smart Contract <a href="#dqntrpyctsbh" id="dqntrpyctsbh"></a>

Modify CrossChainDAO.sol:

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts/access/Ownable.sol";
contract MultXCrossChainDAO is Ownable {
    struct Proposal {
        uint id;
        string description;
        uint yesVotes;
        uint noVotes;
        bool executed;
    }
    mapping(uint => Proposal) public proposals;
    uint public proposalCount;
    address public multxRelayer;
    mapping(uint => mapping(address => bool)) public hasVoted;
 
    event ProposalCreated(uint id, string description);
    event VoteCast(uint id, address voter, bool support);
    event ProposalExecuted(uint id);
    constructor(address _multxRelayer) {
        multxRelayer = _multxRelayer;
    }
    function createProposal(string memory description) public onlyOwner {
        proposals[proposalCount] = Proposal(proposalCount, description, 0, 0, false);
        emit ProposalCreated(proposalCount, description);
        proposalCount++;
    }
      function vote(uint proposalId, bool support) public {
        require(!hasVoted[proposalId][msg.sender], "Already voted");
 
        Proposal storage proposal = proposals[proposalId];
 
        if (support) {
            proposal.yesVotes++;
        } else {
            proposal.noVotes++;
        }
         hasVoted[proposalId][msg.sender] = true;
            emit VoteCast(proposalId, msg.sender, support);
        }
 
        function sendVoteToMultX(uint proposalId, bool support) public {
            require(msg.sender == multxRelayer, "Only MultX relayer can call this");
            vote(proposalId, support);
    }
        function executeProposal(uint proposalId) public {
            Proposal storage proposal = proposals[proposalId];
            require(!proposal.executed, "Already executed");
            require(proposal.yesVotes > proposal.noVotes, "Not enough approvals");
 
            proposal.executed = true;
            emit ProposalExecuted(proposalId);
    }
}
```

#### 2.2 MultX Validator Integration <a href="#j0m7g69be44e" id="j0m7g69be44e"></a>

Validators listen for DAO voting events and relay votes across chains.

**Modify the MultX Relayer Logic**

Instead of token transfers, MultX validators:

1. Monitor governance transactions.
2. Sign votes & forward them to the relayer.
3. The relayer calls sendVoteToMultX() on the target chain.

***

### 3. Secure Treasury Management with MultX <a href="#id-9d4cpqxmr100" id="id-9d4cpqxmr100"></a>

Treasury transactions must be multi-validated before execution.

#### 3.1 Deploy Multi-Sig DAO Treasury Contract <a href="#cieklus8hvn7" id="cieklus8hvn7"></a>

Modify DAOTreasury.sol:

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/access/Ownable.sol";
contract MultXTreasury is Ownable {
    struct Proposal {
        uint id;
        string description;
        uint amount;
        address payable recipient;
        uint yesVotes;
        uint noVotes;
        bool executed;
    }
        Proposal[] public proposals;
        mapping(uint => mapping(address => bool)) public hasVoted;
        address public multxRelayer;
        event ProposalCreated(uint id, string description, uint amount, address recipient);
        event VoteCast(uint id, address voter, bool support);
        event ProposalExecuted(uint id, address recipient, uint amount);
        constructor(address _multxRelayer) {
        multxRelayer = _multxRelayer;
    }
     function createProposal(string memory description, uint amount, address payable recipient) public onlyOwner {
        require(address(this).balance >= amount, "Insufficient funds");
 
        uint id = proposals.length;
        proposals.push(Proposal(id, description, amount, recipient, 0, 0, false));
        emit ProposalCreated(id, description, amount, recipient);
    }
        function vote(uint proposalId, bool support) public {
        require(!hasVoted[proposalId][msg.sender], "Already voted");
 
        Proposal storage proposal = proposals[proposalId];
 
        if (support) {
            proposal.yesVotes++;
        } else {
             proposal.noVotes++;
        }
 
        hasVoted[proposalId][msg.sender] = true;
        emit VoteCast(proposalId, msg.sender, support);
    }
     function executeProposal(uint proposalId) public {
        Proposal storage proposal = proposals[proposalId];
        require(!proposal.executed, "Already executed");
        require(proposal.yesVotes > proposal.noVotes, "Not enough approvals");
 
        proposal.recipient.transfer(proposal.amount);
        proposal.executed = true;
        emit ProposalExecuted(proposalId, proposal.recipient, proposal.amount);
    }
    
        function sendTreasuryVoteToMultX(uint proposalId, bool support) public {
        require(msg.sender == multxRelayer, "Only MultX relayer can call this");
        vote(proposalId, support);
    }
}
```

#### 3.2 How MultX Validators Work with Treasury <a href="#id-4zll9cchjad9" id="id-4zll9cchjad9"></a>

1. A DAO treasury vote is cast on BNB Chain.
2. MultX validators detect & verify signatures.
3. Relayer sends transaction to Ethereum/Polygon.
4. Final approval is executed on the chosen blockchain.

### 4. Integrating MultX in React Frontend <a href="#f1g492hvgac3" id="f1g492hvgac3"></a>

#### 4.1 Send Vote Requests to MultX <a href="#id-2yh29iurs3qd" id="id-2yh29iurs3qd"></a>

Modify App.js:

javascript

```javascript
const MULTX_RELAYER = "0xYourMultXRelayerContract";
const multxAbi = ["function sendVoteToMultX(uint proposalId, bool support) public"];
 
const sendVoteToMultX = async (proposalId, support) => {
    const { signer } = await connectWallet();
    const contract = new ethers.Contract(MULTX_RELAYER, multxAbi, signer);
    await contract.sendVoteToMultX(proposalId, support);
    toast.success(`Vote relayed via MultX for Proposal ${proposalId}!`);
};

```

#### 4.2 Modify UI for Cross-Chain Voting <a href="#id-1kxdmz3i4p8h" id="id-1kxdmz3i4p8h"></a>

jsx

```jsx
<Button variant="contained" onClick={() => sendVoteToMultX(proposal.id, true)}>Vote Yes (MultX Cross-Chain)</Button>
<Button variant="contained" onClick={() => sendVoteToMultX(proposal.id, false)}>Vote No (MultX Cross-Chain)</Button>
```

### 5. Features Implemented <a href="#weutxvd3en47" id="weutxvd3en47"></a>

✅ Cross-Chain DAO Voting with MultX (Secured by multi-validators).\
✅ Multi-Signature Treasury Management (Ensures DAO-controlled fund security).

### 6. Next Steps <a href="#l8ruu0aabbwc" id="l8ruu0aabbwc"></a>

🚀 Future Enhancements:

1. On-Chain Identity Verification (Prevent Sybil Attacks in DAO)
2. ZK-Rollup Governance (Private & Scalable Voting)
3. Tokenized Governance Rewards (Issue LITHO rewards based on activity)
