Payward launched Kraken in September 2013, this fledgling multiple asset trading platform is making waves.  They seem to be one of the few exchanges that have apparently had no effects from the recent increase in Transaction ID Malleability issues.

Very interested to hear what the knowledgeable members of the Bitcoin community think about Kraken a few months on from their arrival...
