Mastercard has launched a service designed to help financial institutions identify fraud, scams and sanctions exposure in stablecoin payments before transactions settle on a blockchain.
A risk check before settlement
The product, called Stablecoin Security, was unveiled Monday at the Money20/20 conference in Las Vegas. It combines Mastercard’s payment intelligence with blockchain analytics to evaluate a transaction throughout its lifecycle—from the point when a payment is initiated to its movement across a public ledger.
The service produces a risk score before funds settle. Financial institutions can use that score within existing fraud-prevention and compliance processes, rather than assessing risk only after a transaction has moved on-chain.
Delivered through a platform-agnostic application programming interface, or API, Stablecoin Security is intended to work with different technology platforms. Its analysis includes signals such as the origin of funds, possible links to restricted parties and indicators associated with scams.
Mastercard launched the initial program with Borderless.xyz and Keyrails. Both companies previously participated in Mastercard’s Start Path blockchain accelerator.
Addressing complex stablecoin transfers
The service is aimed at a challenge that becomes more significant as stablecoins are used for cross-border and business-to-business payments. Stablecoins are digital tokens designed to maintain a stable value, often by being linked to a fiat currency such as the U.S. dollar.
Mastercard cited a Bank for International Settlements study of 593 million stablecoin transfers in 2025. The study found that nearly 60% involved complex, multi-step transactions rather than simple transfers between two parties. That structure can make it more difficult for institutions to follow the full movement of funds and assess exposure along the way.
By combining payment information with blockchain analysis, Mastercard says its new tool is designed to provide a broader view of the transaction journey. The company’s security solutions executive vice president, Ann Johnson, said financial institutions need appropriate intelligence and controls to participate in stablecoin-based payments with confidence.
Part of Mastercard’s wider digital-asset strategy
Stablecoin Security is the latest addition to Mastercard’s efforts to incorporate digital assets into its payments business. The company recently introduced a Global Money Platform with BVNK, the stablecoin infrastructure firm Mastercard acquired in August. The platform allows businesses to hold and move fiat currencies and stablecoins through one connection.
Mastercard has also obtained a New York BitLicense covering stablecoins and tokenized deposits, worked with Coinbase and Ripple on payments involving artificial-intelligence agents, and expanded stablecoin settlement to include Circle’s USDC and Ripple’s RLUSD.
The new service builds on Mastercard products including Crypto Credential and Crypto Secure. It will initially launch in North America. Mastercard said it expects worldwide availability in 2027, including an expansion through BVNK.
