22161918779 refers to the U.S. Senate vote on June 17, 2025, in favor of the "GENIUS Act," which establishes the first federal regulatory framework for stablecoins linked to the U.S. dollar. The law requires issuers of these currencies to maintain full reserves (dollars or treasury bonds) and to disclose the composition of the reserves monthly, and it defines the powers of regulatory bodies to protect users and financial stability; it was approved by a majority of 68 votes to 30 and is now awaiting approval in the House of Representatives and the President's signature.
