Dear Rippex user,
We have reached the end of our closing schedule, which means that our services have been permanently shut down. We sincerely hope that Rippex served as the gateway for many who sought to know the XRP ledger and its decentralized stock market.
We stress once again the importance of your participation in this project and how grateful we are for trust and feedback.
We leave here a final statement with answers to the most frequently asked questions, such as portfolios, incomplete withdrawals and the issuing accounts of Rippex.
Lots of people think they lost their coins and are looking for ways to restore them. Well, good news, you did not lose your coins, wallets are just interfaces on the blockchain which give you access to your coins. With your keys, you are able to access your coins in any other ripple wallet.
