Chris Dixon, a general partner at a16z, asserts that stablecoins are revolutionizing digital payments, akin to WhatsApp's impact on messaging. Stablecoin transaction volumes reached over $12 trillion last year, nearing Visa's $17 trillion, but at significantly lower costs. This shift is transforming money into programmable software, with stablecoins increasingly used for online and international payments. Dixon highlights the regulatory progress in the U.S., with the Genius Act and the proposed Clarity Act setting the stage for stablecoins to integrate into global financial infrastructure. Major companies like Stripe and SpaceX are adopting stablecoins to reduce costs and enhance transaction efficiency. As stablecoins bolster the dollar's dominance, they also drive demand for U.S. Treasury bonds, with issuers like Circle and Tether holding nearly $140 billion in short-term government bonds.
