Washington Federal, the largest bank in Washington State, selected Fiserv‘s DNA account-processing platform, Fiserv announced today. The DNA platform, which includes an innovative app store for Fiserv customers, was originally put together by Open Solutions, acquired by Fiserv one year ago.

“Our partnership with Fiserv is a transformational, long-term investment in the way we deliver value to our customers and stockholders,” said Roy Whitehead, Chairman, President and CEO of Washington Federal. “The unified design of DNA and its flexible, service-oriented architecture will help us roll out new products quickly and easily.”

We asked Fiserv for more details on the deal, but the company declined to provide them.

Washington Federal holds assets totaling $14.4 billion and is one of the nation’s 100 largest banks.
