According to news from the chain, the Ethereum lossless lottery project PoolTogether announced the launch of the V4 version. It currently supports USDC deposited on Polygon and Ethereum, and will provide more options in the future. The new version upgrade includes: funds on different chains in the V4 version can use the same lottery pool, and the shared lottery pool generates more interest, higher bonuses, and lower transaction costs; in the V4 version, the bonus and the number of winners increase with the size of the lottery pool , The V3 version has a fixed number of winners. When the funds enter the lottery pool, the user's probability of winning decreases. After the V4 upgrade, deposit users have more chances to win; the V4 version introduces a governance tool to manage the upper limit of deposits in a single address and limit the number of winnings. In addition, the changes in V4 include that users who do not receive the bonus within 60 days after the award will be returned to the agreement and the V4 version does not have an early withdrawal fee.

PoolTogether stated that users who continue to run the V3 version do not need to upgrade. The only way for users in the V3 version to migrate to the V4 version is to exit V3 and save to V4.
