According to an official announcement on the Rippex blog, Rippex will be closing its gateway by April 2nd, 2018. They are advising anyone who has funds in their Rippex account to withdraw them before this date. However, according to this post, the Rippex Desktop Wallet will not be affected by the closure of Rippex itself. This is because, as they explain, it is a localized gateway to the Ripple network and is based on open source code that you can still access through GitHub. However, the ability to download the wallet was already removed from their site on Feb 28th. According to their post, other communities have expressed interest in hosting the wallet download, but as of yet there is no specific information on who will provide this option. Thus, if you are worried that your computer may be corrupted or lost between now and whenever someone else decides to host the download, you may want to transfer any XRP you may have to another wallet. For instructions on how to move your XRP to a Ledger wallet you can check out this video. To get to your funds on Rippex simply log into your wallet, and send them XRP, minus the 20 XRP base reserve, to whatever XRP wallet you wish to. If you have the Rippex desktop wallet, log into the wallet, click on the Send tab, paste in the address of where you want to send it, enter the amount you want to send, minus the 20XRP base reserve, and then Confirm the send. It should go through in a matter of seconds.
