Major Japanese exchange Coincheck has announced the suspension of a number of services today, including all withdrawals.
While it's not clear at the moment what might have caused the issue, the suspension started when the exchange announced around 13:00 JST (04:00 UTC) that it had restricted deposits, trading and withdrawal of XEM, the token running on the NEM blockchain.
A wider suspension on withdrawals of all cryptocurrencies as well as JPY was announced around 30 minutes later. In the following hour, trading of all cryptocurrencies was also restricted, except bitcoin. According to the latest update, other deposit methods including credit cards have also been stopped.
The exchange so far has not given any statement regarding the cause of issue.
In a statement to CoinDesk, Lon Wong, president of the NEM.io Foundation, said there are no issues with its network, saying:
