Now users can withdraw and sell the XMR tokens, but cannot buy them, and all earlier transaction requests have been cancelled, so traders will have to carry out the transfers again. In addition, while withdrawing, the users will have to confirm the recipient address twice, and same for the sale of the tokens. Also, when sending XMR tokens, there is now a new compulsory field “purpose of the transfer”. All these additional security measures are the result of a hack attack on exchange in January, when Coincheck lost $534 mln worth of NEM tokens.
