ZKasino, a blockchain-based gambling project, has opened a 72-hour refund window for investors to get back their deposited $ETH, following allegations of a $33 million 'rug pull' last month. The project denies attempting to flee with investor funds and has initiated a '2-step bridge back process' for the return of funds at a 1:1 ratio. Investors willing to reclaim their $ETH must return their full ZKasino (ZKAS) token balance and will forfeit any allocated ZKAS and the remaining 14 months of ZKAS release. The refund process has raised concerns among investors about the short window and the potential for the sign-up page to be a scam. ZKasino's Medium post about the refund was not shared by its official account but by 'Derivatives Monke,' a figure at the center of the controversy. This follows the arrest of a suspect involved in the alleged rug pull by Dutch authorities and the return of two-thirds of the stolen funds to ZKasino's multisig wallet. ZKasino has refuted claims of an 'exit scam' or 'rug pull,' amid ongoing scrutiny.
