CryptoBridge had disabled deposits and withdrawals for all PIVX related coins as well as additional masternode and pos V3 coins. This was done as a precautionary measure on behalf of their exchange due to a newly discovered vulnerability related to fake stakes/block spam in POS.
Although it is highly recommended to be using the latest version wallet, this upcoming wallet update will not be mandatory.
The non-mandatory wallet update to resolve the fake stakes/block spam vulnerability has been implemented and is currently being tested.
The Version 3.0.1 wallets should be made available within the next 24 hours. Download links will be made at that time.
