BCB Group, a London-based provider of payment services and business accounts for crypto firms, halted a planned U.S. dollar payments program after regulators shut down Signature Bank earlier today. Shortly after the suspension of Silvergate Bank’s Silvergate Exchange Network on March 3, BCB Group founder and CEO Oliver von Landsberg-Sadie told CoinDesk that the company would roll out U.S. dollar payments tools to help plug the gap. Von Landsberg-Sadie told The Block today that BCB Group already had 6 existing clients ready to test that system as part of a limited pilot program, and said the firm executed its first instant U.S. dollar transaction on March 10.
