DAO

Upgradeable DAO contract for on-chain governance

DAO

Upgradeable DAO contract using UUPS proxy pattern.

Inherits: UUPSUpgradeable, OwnableUpgradeable

Overview

The DAO contract provides:

• Upgradeable governance logic
• Owner-controlled upgrades
• Initializable state

Functions

initialize

function initialize() public initializer

Initializes the DAO contract. Must be called once after deployment.

_authorizeUpgrade

function _authorizeUpgrade(address newImplementation) internal override onlyOwner

Authorizes an upgrade to a new implementation. Only callable by owner.

Deployment

The DAO uses the UUPS (Universal Upgradeable Proxy Standard) pattern:

import "@luxdao/DAO.sol";
import "@openzeppelin/contracts/proxy/ERC1967/ERC1967Proxy.sol";

// Deploy implementation
DAO implementation = new DAO();

// Deploy proxy
ERC1967Proxy proxy = new ERC1967Proxy(
    address(implementation),
    abi.encodeCall(DAO.initialize, ())
);

// Use proxy as DAO
DAO dao = DAO(address(proxy));

Upgrading

To upgrade the DAO:

// Deploy new implementation
DAOV2 newImplementation = new DAOV2();

// Upgrade (only owner)
dao.upgradeToAndCall(address(newImplementation), "");

Security

• UUPS Pattern: Upgrade logic in implementation, not proxy
• Owner-Only Upgrades: Only owner can authorize upgrades
• Initializer Guard: initialize() can only be called once
