Guesslot is a non-custodial and decentralized protocol that provides users with lossless prediction services. Prizes are generated on the interest earned on deposited funds through superior and safe lending protocols like Aave. After depositing funds into the Guesslot protocol, users can participate in the prediction with the deposit certificate. At the end of the prediction, the protocol obtains the results from the decentralized oracle and publishes the winning results according to the rules. The winning users divide up the prizes, and the non winning users can withdraw all their deposit without any loss.
