"It’s our job to ensure that as our company grows, so does our ability to ensure that our fans can be confident in the sanctity and integrity of every game, every day," FanDuel's release said.

The moves to boost transparency and security come as federal lawmakers and state authorities have shown an increasing interest in the daily fantasy industry. Multiple members of Congress, including Senate Minority Leader Harry Reid (D-Nev.), said Tuesday that lawmakers should examine the industry in the wake of the scandal, and the House Energy and Commerce Committee is expected to hold a hearing about daily fantasy in the months ahead.

New York Attorney General Eric Schneiderman launched his own investigation into the companies Tuesday, adding to the list of state attorneys general and gaming commissions that are weighing issues around daily fantasy's legality.
