A crypto exchange platform backed by the billionaire Winklevoss twins has submitted a confidential filing for an initial public offering (IPO) with the U.S. Securities and Exchange Commission (SEC).

Gemini, a crypto exchange run by billionaire twins Tyler and Cameron Winklevoss, on Friday disclosed it had confidentially filed for a U.S. initial public offering, as digital asset firms seize on renewed market momentum.

Founded by the Winklevoss twins in 2014, Gemini has had a tumultuous road to its public offering.
