According to @EmberCN, the ZKasino_io project has yet to issue refunds to users. The founder, @Derivatives_Ape, announced on May 28 that users could register for ETH refunds within a three-day window. However, there has been no follow-up since the registration period ended. The 10,515 ETH meant to be refunded is currently held in two addresses. Users with funds in these addresses should monitor the situation closely.
