# BaseLaunchHoldersDistributorFactory

Creates one holders distributor per holders-mode launch as a clone of a single implementation whose code cannot change, and holds the publisher key every distributor trusts to post reward epochs.

Creates one holders distributor per launch as an EIP-1167 clone of a fixed implementation deployed with this factory. Clones are not upgradeable, so a distributor's code is fixed for its whole life. The owner's only power is rotating `publisher`, the key allowed to post reward epochs on every distributor. A publisher can allocate a distributor's `available()` balance but can never reach an allocation that is already published and still claimable.

### Read functions (7)

| Function | What it does |
| --- | --- |
| [feeEscrow](#feeEscrow) `feeEscrow() view returns (address)` selector 0xc4b7de97 Anyone | The fee escrow distributors harvest creator fees from. |
| [implementation](#implementation) `implementation() view returns (address)` selector 0x5c60da1b Anyone | The code every distributor clone runs. |
| [launchFactory](#launchFactory) `launchFactory() view returns (address)` selector 0x536dac9b Anyone | The launch factory every distributor binds against. |
| [owner](#owner) `owner() view returns (address)` selector 0x8da5cb5b Anyone | Returns the address of the current owner. Inherited from Ownable. |
| [pendingOwner](#pendingOwner) `pendingOwner() view returns (address)` selector 0xe30c3978 Anyone | Returns the address of the pending owner. Inherited from Ownable2Step. |
| [publisher](#publisher) `publisher() view returns (address)` selector 0x8c72c54e Anyone | The key allowed to publish reward epochs, read live by every distributor. |
| [renounceOwnership](#renounceOwnership) `renounceOwnership() pure` selector 0x715018a6 Anyone | Permanently disabled, so the publisher key always stays rotatable. |

### Write functions (4)

| Function | What it does |
| --- | --- |
| [acceptOwnership](#acceptOwnership) `acceptOwnership()` selector 0x79ba5097 Pending owner | The new owner accepts the ownership transfer. Inherited from Ownable2Step. |
| [create](#create) `create(address creator) returns (address distributor)` selector 0x9ed93318 Anyone | Deploys a new distributor. Permissionless: a distributor only ever receives the fees of a launch that names it as recipient. |
| [setPublisher](#setPublisher) `setPublisher(address publisher_)` selector 0xcab63661 Owner | Rotates the epoch publisher for every distributor. |
| [transferOwnership](#transferOwnership) `transferOwnership(address newOwner)` selector 0xf2fde38b Owner | Starts the ownership transfer of the contract to a new account. Replaces the pending transfer if there is one. Can only be called by the current owner. Setting `newOwner` to the zero address is allowed; this can be used to cancel an initiated ownership transfer. Inherited from Ownable2Step. |

### Events (4)

| Event | What it means |

Two launcher sets on Base

Addresses are listed for launcher 2.1.0, where new coins launch, and for launcher 2.0, which keeps serving the coins launched before the cutover. A coin stays on the set that launched it. The functions and events are the 2.1.0 contracts'; the 2.0 contracts are an earlier version of the same code and have no interface registry, so check a 2.0 contract's verified source on Basescan before relying on a detail listed here.

How the fees are split is on [fees](https://baselaunch.app/fees), what the owner can and cannot change is on [security](https://baselaunch.app/security), and short answers are in the [FAQ](https://baselaunch.app/faq).

Meme coins are highly speculative and most lose their value. Nothing here is financial advice.
