Bitcoin Cash Balances and Vulnerability Reduction

KeepKey is pleased to announce that we have updated the beta version of the KeepKey client and device firmware. This release includes showing Bitcoin Cash (BCH) balances in Bitcoin accounts. This is part of our ongoing effort to add full support for this new cryptocurrency. BCH was forked from Bitcoin earlier this month. Anyone who was holding Bitcoin at the time of the fork automatically received BCH.

Support for Bitcoin Cash is a top priority for us. The next step will be to implement the ability to send Bitcoin Cash to a BCH account on your KeepKey or to any other BCH address. It will also support exchanging BCH for other currencies using the built in Shapeshift support.

Additionally, this release includes a firmware update. This update addresses a potential vulnerability that was described by a security researcher at Defcon last month. The vulnerability is fairly minor and is already mitigated by an exponential time delay after an incorrect PIN entry. Out of an abundance of caution, we decided to further address the vulnerability with a minor change to the firmware.
