SquareFinancial.com has been acquired by a currently unknown CSC Corporate Domains client, using generic whois data. Payment service Square Inc. (SquareUp.com) are the most likely buyers. Square.com does redirect to SquareUp.com and is owned by Square Enix Holding Co. and may be leased as noted by
@GeorgeKirkos after I noted that Square Enix Holding Co were potential buyers earlier due to them being in whois on Square.com. The domain name held an offering price of $14,999. The domain was for sale using Efty but sold on Afternic.
