Update: Kraken says it has implemented a fix and is currently monitoring the results.

Cryptocurrency exchange Kraken says it is currently investigating an issue with several crypto funding gateways, including major ones such as Bitcoin (BTC), Ether (ETH) and ERC-20. 

On June 6, Kraken’s status page said, “Deposits and withdrawals are currently delayed. We will provide any updates as soon as possible.”

The first notice was posted around 7:44 am UTC, followed by two updates saying it continues to “work on a fix” for the issue. The status page did not make it clear what was causing the problem.

This is a developing story; further information will be added as it becomes available.
