DAO can deploy LP token with special contract (Shop). Shop can mint LP. Anyone can burn owned LP and get all the share from DAO.

        uint256 _amount,

    ) external nonReentrant returns (bool) {

        require(_amount <= balanceOf(msg.sender), "LP: insufficient balance");
        require(totalSupply() > 0, "LP: Zero share");

        uint256 _share = (1e18 * _amount) / (totalSupply());

        _burn(msg.sender, _amount);
