Source: contracts/DAOPresale.sol (Note: Update link if necessary)

The DAOPresale.sol contract provides the implementation logic for an optional token presale module. Instances of this contract are deployed via DAOPresaleProxy contracts, initiated through a proposePresale governance proposal executed by the DAO contract.

​
Key Concepts

  • Optional Module: Not deployed by default with a new DAO. Added later via governance.
  • Token Sale: Facilitates the sale of a specified amount of the DAO’s governance token (DAOToken) at a set initial price (usually in the native currency, e.g., ETH).
  • DAO Controlled: Deployment, funding (transferring tokens from Treasury), pausing/unpausing, and withdrawal of collected funds are all controlled by the main DAO contract through specific proposal types (proposePresale, proposePresalePause, proposePresaleWithdraw).

​
Expected Functionality (Based on common patterns and DAO interactions)

(This section is a placeholder and will be updated after analyzing DAOPresale.sol)

  • buyTokens(): A payable function allowing users to send native currency (e.g., ETH) to purchase DAOToken at the defined price during the active sale period.
  • claimTokens(): If tokens are not transferred immediately upon purchase (e.g., vesting or post-sale claim), this function allows buyers to claim their purchased tokens.
  • withdrawToTreasury(): Allows the controlling DAO (via proposePresaleWithdraw proposal) to withdraw the collected native currency from the presale contract to the DAOTreasury.
  • setPaused(bool pause): Allows the controlling DAO (via proposePresalePause proposal) to pause or unpause the sale (e.g., stop buyTokens calls).
  • initialize(address token, address treasury, uint256 amount, uint256 initialPrice): An initializer function called by the proxy during deployment (triggered by _executePresale in DAOExecutor), setting up the presale parameters (token being sold, treasury address for withdrawals, total amount for sale, price).

​
Events

(This section is a placeholder)

  • TokensBought(address indexed buyer, uint256 ethAmount, uint256 tokenAmount): Emitted when a user successfully buys tokens.
  • TokensClaimed(address indexed claimer, uint256 amount): Emitted when a user claims purchased tokens (if applicable).
  • Withdrawal(address indexed treasury, uint256 amount): Emitted when collected funds are withdrawn to the treasury.
  • PausedStateChanged(bool isPaused): Emitted when the presale contract is paused or unpaused.

​
Upgradeability

Uses the UUPS proxy pattern. Upgrades are managed via the DAO contract’s proposeModuleUpgrade governance process, specifically targeting the DAOPresaleProxy address.
