Metagovernance

Consider a scenario in which we have some master organization with its own DAO, further subdivided into several slave organizations, each equipped with an independent DAO. In this setup, only the slave DAOs have the ability to vote in the master one. Such a hierarchical structure is called metagovernance and can be established using our protocol.
To make this happen, metagovernance proposals allow you to vote in one DAO on behalf of another. It's achievable by the limiting the executor to one of the deployed DAO pools, specifically the master DAO. The data included is restricted to the deposit and approval of funds, and the last action is exclusively a vote for the proposal in the master DAO (in the actionsFor list) and a vote against it (in the actionsAgainst list).
It's important to note that the actionsAgainst parameter is only non-empty in metagovernance proposals. The GovPool contract enforces a validation process to ensure that proposals specifying actionsAgainst adhere to the established criteria for metagovernance proposals. Specifically, actionsFor and actionsAgainst should have the same length and parameters, except for the last one, where the isVoteFor parameter differs.
Apart from ordinary proposals, metagovernance proposals can be executed if the quorum against is reached. In such cases, the proposal status will change to ExecutedAgainst, and all users who voted against will receive rewards.
Here's an example of creating a proposal that votes in the master DAO on behalf of the slave DAO.
function metagovernanceProposal(IGovPool masterGovPool, IGovPool slaveGovPool) external {
(, address masterUserKeeperAddress, , , ) = masterGovPool.getHelperContracts();
address tokenAddress = IGovUserKeeper(masterUserKeeperAddress).tokenAddress();
require(tokenAddress != address(0), "Zero token");
uint256 proposalId = 1;
uint256 amount = 10 ether;
uint256[] memory nftIds = new uint256[](0);
require(
IERC20(tokenAddress).balanceOf(address(slaveGovPool)) >= amount,
"Insufficient balance"
);
require(
masterGovPool.getProposalState(proposalId) == IGovPool.ProposalState.Voting,
"Not voting state"
);
IGovPool.ProposalAction[] memory actionsFor = new IGovPool.ProposalAction[](3);
IGovPool.ProposalAction[] memory actionsAgainst = new IGovPool.ProposalAction[](3);
actionsFor[0] = actionsAgainst[0] = IGovPool.ProposalAction({
executor: tokenAddress,
value: 0,
data: abi.encodeWithSelector(IERC20.approve.selector, masterUserKeeperAddress, amount)
});
actionsFor[1] = actionsAgainst[1] = IGovPool.ProposalAction({
executor: address(masterGovPool),
value: 0,
data: abi.encodeWithSelector(IGovPool.deposit.selector, amount, nftIds)
});
/// @dev vote for the proposal in the master DAO
actionsFor[2] = IGovPool.ProposalAction({
executor: address(masterGovPool),
value: 0,
data: abi.encodeWithSelector(IGovPool.vote.selector, proposalId, true, amount, nftIds)
});
/// @dev vote against the proposal in the master DAO
actionsAgainst[2] = IGovPool.ProposalAction({
executor: address(masterGovPool),
value: 0,
data: abi.encodeWithSelector(IGovPool.vote.selector, proposalId, false, amount, nftIds)
});
slaveGovPool.createProposal("Metagovernance proposal", actionsFor, actionsAgainst);
}
