Mastercard Launches Stablecoin Security Tool to Screen Payments for Fraud and Money Laundering Risks

Mastercard has introduced a new risk intelligence solution designed to help financial institutions identify fraud, scams, sanctions exposure and other financial crime risks associated with stablecoin payments. The product, called Stablecoin Security, combines conventional payment information with blockchain analytics to assess transactions before funds are transferred on-chain and throughout the payment process.

Announced on 19 October 2026 at the Money20/20 USA conference in Las Vegas, the solution is intended to give banks and payment providers greater visibility over the origin and movement of funds when processing stablecoin transactions. Mastercard is working with Borderless.xyz and Keyrails as its initial partners, with commercial availability expected worldwide in 2027 following an initial launch in North America.

Stablecoins are digital assets designed to maintain a relatively stable value, typically by referencing a fiat currency such as the US dollar. They are increasingly used for cross-border payments, business transactions and settlement. However, transactions can pass through multiple wallets and intermediaries, making it difficult for financial institutions to assess the risks associated with the complete payment chain.

Mastercard cited research covering 593 million stablecoin transfer events across 141 million Ethereum transactions in 2025. The analysis found that nearly 60% of the transfer events formed part of complex, multi-step transactions rather than straightforward transfers between two parties. Such transaction structures can make it harder to establish the origin of funds, identify connections to suspicious activity and assess the risk associated with a payment before it is completed.

Stablecoin Security is designed to address this challenge by combining information about the payment itself with blockchain-based risk indicators. The system can assess transaction context, the source of funds, potential exposure to restricted parties and indicators associated with scams or other financial crime. It then generates risk intelligence, including a risk score before a payment is completed, to support a financial institution’s decision on whether the transaction should proceed or receive further review.

The service is delivered through an application programming interface (API), allowing institutions to integrate its capabilities into existing fraud detection, compliance and case management systems. Mastercard says the platform-agnostic design is intended to enable financial institutions to incorporate stablecoin risk assessment without establishing a separate operational framework for digital asset transactions.

The solution is intended to support payments across the fiat and stablecoin lifecycle. For example, a business paying an overseas supplier through a bank that uses stablecoins could have the transaction assessed before the funds are transferred on-chain. The bank could use the resulting risk information to determine whether additional checks are necessary before authorising the payment.

Borderless.xyz and Keyrails are the initial partners supporting the introduction of the service. Borderless.xyz connects financial institutions with licensed stablecoin providers across more than 113 countries and 72 currencies, while Keyrails focuses on high-value cross-border trade payments, particularly in emerging markets.

Both companies have participated in Mastercard’s Start Path Blockchain and Digital Assets programme, which engages with businesses developing services in the digital asset sector. Their involvement is intended to help bring the risk intelligence capabilities into real-world payment arrangements.

The launch forms part of Mastercard’s wider expansion into digital assets and blockchain-based financial infrastructure. The company has developed other services aimed at improving security and trust in digital asset transactions, including Mastercard Crypto Credential and Crypto Secure. It has also expanded support for stablecoin-based settlement and announced the acquisition of stablecoin infrastructure provider BVNK in 2026.

Mastercard expects to expand Stablecoin Security’s reach during 2027, including through BVNK. Global commercial availability is expected during that year, although the timing and scope of deployment may depend on implementation and regulatory considerations.

The introduction of the service comes as financial institutions face growing pressure to assess financial crime risks associated with digital asset payments while supporting faster cross-border settlement. Conventional payment screening and blockchain analytics provide different types of information, and combining them may help institutions identify risks that would be harder to detect by examining either payment data or on-chain activity in isolation.

Stablecoin Security is intended to provide additional risk intelligence to support institutions’ existing controls. The product does not replace the legal obligations of banks and payment providers to conduct customer due diligence, monitor transactions, comply with sanctions requirements or report suspicious activity where required. Financial institutions will continue to be responsible for applying their own controls and making decisions in accordance with applicable laws and regulations.
