Mastercard launched Stablecoin Security at Money20/20 on Oct. 19, an API that scores stablecoin payments for fraud, scams and sanctions exposure before settlement, with Borderless.xyz and Keyrails as first participants.

Mastercard is putting a risk score in front of stablecoin payments. Unveiled Monday at the Money20/20 conference in Las Vegas, the product called Stablecoin Security lets banks and payment providers screen dollar-token transfers for fraud, scams, and sanctions exposure before funds move, the company said in a Monday release covered by Decrypt and Cointelegraph.
Stablecoin Security combines Mastercard's existing payment intelligence with blockchain analytics. It follows a payment from initiation through its path on public ledgers, weighing signals like where funds originated, exposure to restricted parties, and known scam patterns. The output is a risk score generated before settlement, delivered through an API that Mastercard describes as platform-agnostic, so it can sit inside compliance and fraud systems banks already run.
The pitch addresses a structural difference between card payments and token transfers. Card fraud can often be reversed at the network layer. On-chain stablecoin payments frequently cannot. And as Cointelegraph noted, stablecoins add complexity because funds hop across multiple wallets and chains, which makes it hard to judge risk across the whole journey rather than a single hop.
Mastercard cited a Bank for International Settlements study of 593 million stablecoin transfers in 2025 that found nearly 60% were complex, multi-step transactions instead of simple one-to-one payments. That is the shape of traffic the tool is aimed at: cross-border and business-to-business flows where an institution cannot see the full route from its own window.
"Stablecoins are creating new possibilities for value exchange, but financial institutions need the right intelligence and controls to participate with confidence," said Ann Johnson, Mastercard's executive vice president of security solutions.
Two program participants go first: Borderless.xyz and Keyrails, both graduates of Mastercard's Start Path blockchain accelerator. Borderless has already worked with Mastercard on shared identity checks for stablecoin transfers. The launch is limited to North America, with global availability planned for 2027, including delivery through BVNK, the stablecoin infrastructure firm Mastercard acquired in August for $1.8 billion.
What is not in the launch materials: the chains the analytics cover, which stablecoins qualify, pricing for the API, and the banks or payment firms beyond the two named participants. Mastercard said rollout details expand as the product moves outside North America.
Banks already run sanctions and fraud screening on wires and card authorizations. The checklist is familiar: originator, beneficiary, geography, watchlists, behavioral patterns. Stablecoins broke that checklist in two ways. First, the transfer itself is final once broadcast, so the screening window is narrower and the reversibility is lower. Second, the same payment can appear as a chain of wallet hops across several networks, and any single hop can look clean while the route does not.
Stablecoin Security is Mastercard's answer to the second problem for institutions that want the first problem handled inside the tools they already staff. The risk score is meant to slot into existing compliance queues rather than force a separate crypto-only workflow. That framing is deliberate. The buyers here are not crypto-native desks. They are banks and payment companies adding tokenized dollars to products that already had a fraud department.
Stablecoin Security is one more block in a wall Mastercard has been laying all year. The Global Money Platform, powered by BVNK, lets businesses hold and move fiat and stablecoins through a single connection. The company holds a New York BitLicense covering stablecoins and tokenized deposits. It enabled AI-agent payments alongside Coinbase and Ripple, and expanded stablecoin settlement to Circle's USDC and Ripple's RLUSD. Mastercard said the new tool builds on existing products like Crypto Credential and Crypto Secure.
The timing is not only about demand. Stablecoin supply growth slowed sharply this year even as transaction volume accelerated, driven by remittances and cross-border payments, Cointelegraph reported. A Standard Chartered forecast cited there puts the market at $2 trillion by 2030, two years later than the bank's earlier call. The institutions Mastercard sells to are planning for volume without pretending the risk questions are settled.
