Mastercard Launches Tool to Detect Stablecoin Fraud Before Payments Settle

Mastercard is expanding its fraud prevention services into the stablecoin market with a new security tool designed to help banks identify risky transactions before funds move across blockchain networks.

Announced Monday at the Money20/20 USA conference, Mastercard Stablecoin Security combines traditional payment information with blockchain analytics to detect potential scams, fraud, sanctions exposure and other financial crime risks. The service can generate a risk score before a transaction is completed, giving financial institutions an opportunity to review suspicious payments before settlement.

Borderless.xyz and Keyrails are the first partners to work with the new service. Mastercard expects the product to become commercially available worldwide next year.

The launch addresses a growing challenge for banks and payment providers as stablecoins become more widely used for digital payments. Unlike traditional bank transfers, blockchain transactions can pass through multiple wallets and networks, making it more difficult for financial institutions to track the movement of funds and identify suspicious activity.

Once a stablecoin transfer has been confirmed on a blockchain, recovering the funds can be difficult. Mastercard's new tool aims to give banks an additional layer of protection by assessing potential risks before a payment is completed, rather than relying solely on monitoring systems that detect suspicious activity after the fact.

The initiative also adds to Mastercard's broader investment in digital asset infrastructure. In August, the company acquired stablecoin infrastructure provider BVNK in a deal valued at $1.8 billion. Mastercard has also introduced plans for a Global Money Platform aimed at helping businesses make payments using stablecoins.

The company's latest move comes as stablecoins continue to gain traction in cross-border payments and remittances. Although growth in the overall supply of digital dollar tokens has slowed considerably this year, transaction volumes have accelerated, reflecting increased use of stablecoins to transfer money between countries and across financial platforms.

Market projections point to further expansion in the years ahead. A recent report from Standard Chartered estimates that the stablecoin market could reach $2 trillion by 2030, pushing its previous timeline back by two years.

As banks and payment companies explore stablecoins for faster and more flexible transfers, tools that combine conventional payment monitoring with blockchain data could become increasingly important. Mastercard's new service is designed to help financial institutions manage these risks while supporting the growing use of blockchain-based payments.
