I spent Monday, the first full day of Money20/20 USA at The Venetian, moving between the Meridian and Intersection stages with a recorder running. By the afternoon I could have written the same sentence under every session. Nobody I heard was still arguing about whether stablecoins or AI agents work. The argument was about who carries the risk when they do something nobody intended.
It started with Mastercard. Just before its late-morning stablecoin panel, Ann Johnson, who runs security solutions at Mastercard, launched Stablecoin Security, a risk score for stablecoin payments that combines 16 years of the network’s fraud, identity and cyber intelligence with blockchain analytics and is built to work at machine speed. Her framing was simple: “the thing that allows innovation to scale is trust.” Mastercard says it will launch in North America first, with worldwide availability expected in 2027.
The panel that followed made the case for why it is needed. Rajpal Khangura , co-founder and chief compliance officer of Keyrails , settles trade payments for merchants in markets such as Nigeria paying suppliers in China, with an average ticket of $250,000 to $350,000. His customers used to ask only how cheap and how fast; now they ask how safe the wallet is, and how safe the fiat is when it lands. His hardest problem is the wallet that is not sanctioned itself but has transacted a few hops away from one that is, and keeping his own risk appetite in step with every bank and liquidity partner downstream.
