These lotteries have the following characteristics: * **No Entry Fee**: Participation is completely free for eligible users. * **Eligibility Criteria**: Only wallets that meet specific on-chain requirements (e.g., holding a certain token, interacting with a protocol, or completing a quest) can join. * **Project-Funded Rewards**: The prize pool is sponsored by the project organizing the lottery. * **Trigger Conditions**: Lotteries can start when a target participant count is reached or a deadline is met. These lotteries allow projects to grow their communities, drive targeted behavior, and reward valuable users in a decentralized and verifiable way.
