# Lotellar-Generated Lotteries

Lotellar-generated lotteries are predefined lottery types with the following characteristics:

* **Fixed Entry Fee**: Each lottery requires participants to pay a specific amount to join.
* **Fixed Participant Count**: A lottery only starts once the defined number of participants have entered.
* **Auto-Renewal**: Upon completion (i.e., once a winner is selected), a new lottery of the same configuration is automatically created and made available.

This mechanism enables continuous participation without requiring manual setup for each round. Lotellar ensures fairness and automation by using verifiable randomness (VRF) to select winners.
