Mastercard launches stablecoin security tool with partners

Mastercard has launched Stablecoin Security, a risk-intelligence product for stablecoin payments, with Borderless.xyz and Keyrails as its first partners.

The product is aimed at financial institutions seeking greater visibility into fraud, sanctions exposure, scams and other financial-crime indicators across the full path of a stablecoin transaction. It is designed to assess risk from the point a payment is initiated through to the movement of funds on-chain.

The launch comes as stablecoins take on a larger role in cross-border payments and business-to-business transactions. Banks and payment providers have been testing ways to use digital tokens linked to fiat currencies for settlements across markets, but risk controls remain a central obstacle to wider adoption.

The new service combines payment intelligence with blockchain analytics. Offered through a platform-agnostic application programming interface, it generates a risk score before a payment is completed, allowing institutions to feed the information into existing fraud, compliance and case-management systems.

A study cited by Mastercard found that nearly 60% of 593 million stablecoin transfer events examined across 141 million Ethereum transactions were complex, multi-step transfers rather than simple one-to-one payments. That complexity can make it harder for financial institutions to assess exposure across a payment journey involving multiple intermediaries, currencies and jurisdictions.

In practical terms, the product analyses transaction context, the source of funds, exposure to restricted parties and scam indicators. Mastercard says this can help institutions support stablecoin payments without setting up a separate risk operating model for digital-asset transactions.

One example involved a coffee-shop owner in Boston paying a supplier in Brazil. In that scenario, a bank uses stablecoins to move funds across borders, while the bank's service provider uses Mastercard's product to review payment and blockchain intelligence before deciding whether the transfer should proceed or require further review.

Partner network

The first external partners are Borderless.xyz and Keyrails, both of which have participated in Mastercard's Start Path Blockchain and Digital Assets program. The partnerships suggest Mastercard is targeting payment companies that already handle real-world cross-border settlement flows rather than limiting the product to pilot projects.

Borderless.xyz provides financial institutions with a single connection to licensed stablecoin providers in more than 113 countries and 72 currencies, according to Mastercard. Keyrails focuses on high-value cross-border trade payments, especially in emerging markets.

"Stablecoins are creating new possibilities for value exchange, but financial institutions need the right intelligence and controls to participate with confidence," said Ann Johnson, Executive Vice President, Security Solutions, Mastercard. "By bringing payment and blockchain insights together, Stablecoin Security extends Mastercard's fraud and risk capabilities to digital-asset payments, giving institutions a clearer view of risk to make more informed decisions and build greater trust."

Alex Garn, Chief Product Officer at Borderless.xyz, outlined the operational case for the service. "Stablecoin payments should be simple to launch and manage, even when the infrastructure behind them is complex," Garn said. "Working with Mastercard will help give financial institutions the context they need to manage risk across providers, markets and currencies without adding another layer of operational complexity."

Rajpal Khangura, Co-Founder and Chief Compliance Officer at Keyrails, linked the launch to trade settlement. "Global trade needs trusted infrastructure for stablecoin settlement," Khangura said. "Working with Mastercard strengthens the risk intelligence behind high-value trade payments, helping institutions move money across borders with greater visibility, confidence and settlement certainty."

Broader push

The launch adds to Mastercard's broader effort to build tools around digital assets and stablecoin-based payments. Stablecoin Security sits alongside other products including Mastercard Crypto Credential and Crypto Secure, reflecting a wider attempt to apply card-network-style controls and monitoring to blockchain-linked payment flows.

Mastercard also plans to expand the product's reach through BVNK, the stablecoin infrastructure provider it acquired in August 2026. North America is the first launch market, with commercial availability expected to broaden worldwide in 2027.

Kimberly Mescal Julien, Global Head of Partnerships at BVNK, pointed to the security demands created by wider adoption. "As stablecoins become more embedded in global payments, security needs to evolve alongside the technology," Julien said. "We look forward to exploring how innovations such as this can help strengthen the infrastructure underpinning stablecoin transactions and support the ecosystem's continued growth."
