# newFactory1.sol

This is a smart contract named DAOFactory that creates and manages DAOs (Decentralized Autonomous Organizations). The contract has several mappings that keep track of various properties of DAOs, such as their parent-child relationships, associated token contracts, and existence.

The contract uses the SPDX-License-Identifier to specify the license under which the contract is released. In this case, it is the GNU General Public License version 3.0.

The contract specifies the Solidity version requirement as >=0.7.0 <0.9.0, and also imports several other contracts using import statements.

The contract defines a constructor that takes an address parameter for the myCreator contract, which is used to create tokens.

  • createDAOTop: Creates a new top-level DAO. It takes several string parameters for the name and description of the DAO, as well as the names and symbols of two associated token contracts. The function first checks that the caller is an approved DAO creator before creating two new token contracts using the my_creator contract. It then creates a new MyDAO contract, passing in various parameters including the new token contracts and DAOFactory contract itself. The function also assigns allowances of tokens to the DAO contract, assigns the DAO to use the YK and voter tokens, and transfers tokens from the factory to the DAO contract. Finally, the function updates several mappings to keep track of the new DAO.

The child DAOs are created with their own YK and voter tokens, which are used to participate in voting and decision-making processes within the DAO.

# Functions:

  1. createChildDAO: This function is used to create a new child DAO under a parent DAO. It takes the following parameters:
  • parent: The address of the parent DAO contract.
  • dao_name: The name of the new DAO.
  • dao_description: A brief description of the new DAO.
  • yk_token_name: The name of the YK token to be used by the new DAO.
  • yk_token_symbol: The symbol of the YK token to be used by the new DAO.
  • voter_token_name: The name of the voter token to be used by the new DAO.
  • voter_token_symbol: The symbol of the voter token to be used by the new DAO.

The function first checks if the caller has YK privileges in the parent DAO. If the caller is not a YK of the parent DAO, the function throws an error. It then creates new YK and voter token contracts using a token creator contract. The function then creates a new child DAO contract with the specified parameters and assigns the YK and voter tokens to the new DAO. The function also saves the associations between the DAO and its tokens, marks the child DAO as existing, adds the child DAO to the parent's list, increments the number of children for the parent DAO, and sets the parent DAO for the child. Finally, the function transfers tokens from the factory to the child DAO contract, stores the child DAO contract, and increments the DAO ID for the next DAO creation.

  1. mint_dao_yk: This function is used to mint new YK tokens for a specified child DAO. It takes the following parameters:
  • to_be_minted: The child DAO contract to mint the YK tokens for.
  • amount: The amount of YK tokens to mint.
  • sender: The address of the YK token holder.

The function first checks if the caller is a YK of the selected DAO. If the caller is not a YK of the selected DAO, the function throws an error. It then checks if the caller is the DAO itself. If the caller is not the DAO, the function throws an error. Finally, the function mints the specified amount of YK tokens for the child DAO.

  1. mint_dao_voter: This function is used to mint new voter tokens for a specified child DAO. It takes the following parameters:
  • to_be_minted: The child DAO contract to mint the voter tokens for.
  • amount: The amount of voter tokens to mint.
  • sender: The address of the YK token holder.

The function first checks if the caller is a YK of the selected DAO. If the caller is not a YK of the selected DAO, the function throws an error. It then checks if the caller is the DAO itself. If the caller is not the DAO, the function throws an error. Finally, the function mints the specified amount of voter tokens for the child DAO.

  1. addCreator(address input_creator): Adds a new address to the list of DAO creators.
  • input_creator: The address to be added as a DAO creator.
  • public: The function can be called from outside the contract.
  • Returns: None.
  • Example usage: addCreator(0x1234567890123456789012345678901234567890);
  1. getParentDAO(MyDAO mydao): Retrieves the parent DAO of a given child DAO.
  • mydao: The child DAO contract for which to retrieve the parent DAO.
  • public view: The function can be called from outside the contract and does not modify any state variables.
  • Returns: The parent DAO contract.
  • Example usage: getParentDAO(mydao);
  1. getCurrentDAO(uint256 id): Retrieves the DAO contract based on its ID.
  • id: The ID of the DAO to retrieve.
  • public view: The function can be called from outside the contract and does not modify any state variables.
  • Returns: The DAO contract.
  • Example usage: getCurrentDAO(123);
  1. delete_DAO(MyDAO to_be_deleted, address sender): Deletes a DAO and its child DAOs recursively.
  • to_be_deleted: The DAO contract to be deleted, sender - the address of the sender requesting the deletion.
  • public: The function can be called from outside the contract.
  • Returns: None.
  • Example usage: delete_DAO(mydao, 0x1234567890123456789012345678901234567890);
