DAD Prize Pool (No Loss Lottery)
DAD prize pool is similar to vaults and purpose is to generate yield on deposited EOS, but instead of accumulating yield in the dToken, it reserves the yield in the contract and draw a lucky winner every week to claim all accumulated yield. Each user received a pool token (DPPEOS) in equal amount of deposited EOS. Each DPPEOS token enables 10,000 tickets for the draw. More tickets enables higher probability for user to win the prize.
Users who deposit the tokens in the No Loss Prize Pool can withdraw their contribution anytime without any loss. If the withdrawal is made before draw, they lose their tickets for the current week while they get their original EOS back as 1DPPEOS = 1 EOS always.
