PoolTogether is a protocol for no-loss prize games on Ethereum. Modelled on the well-established concept of “no loss lotteries” and “prize savings accounts” the protocol offers a chance to win prizes in exchange for depositing funds. Even if you don’t win, you keep all your deposited funds. Prizes are made up of the interest that accrues on all users deposits. The protocol relies on the third-party random number generator service ChainLink to provide randomness to pick lottery winners.
The PoolTogether Protocol is controlled by POOL token holders. All changes to the protocol are submitted and approved. The protocol automatically distributes the POOL token to anyone who deposits into the protocol. POOL token is currently trading in Uniswap.
