The Consumer Financial Protection Bureau (CFPB) has sued the operator of Zelle—as well as Bank of America, JPMorgan Chase, and Wells Fargo—for failing to protect consumers on the peer-to-peer payment network.

The Consumer Financial Protection Bureau sued JPMorgan Chase & Co., Bank of America Corp. and Wells Fargo & Co. along with the parent company of Zelle alleging the firms rushed a peer-to-peer payment network to market without adequate consumer protections.

The Consumer Financial Protection Bureau made the announcement Friday and claims that Americans have lost hundreds of millions of dollars to fraud connected to poor safeguards for the peer-to-peer payment network. JPMorgan Chase is also listed in the lawsuit.
