"We are honored to have GSR Capital as a strategic investor," said tZERO CEO Saum Noursalehi in a statement. "The tokenization of securities has the potential to disrupt global capital markets responsible for moving hundreds of trillions of dollars. Together with our partners, we will globalize our blockchain-based platform, bringing more efficiency, liquidity, and trust to capital markets."
