Mastercard is extending its reach into stablecoin payments with a new security system designed to spot fraud, scams, and sanctions risks before funds reach the blockchain. Announced Oct. 19, 2026, Stablecoin Security combines traditional payment intelligence with blockchain analytics. Borderless.xyz and Keyrails are the initial partners, with a North American launch preceding broader commercial availability worldwide in 2027.
Unveiled at Money20/20 USA in Las Vegas, the new offering combines payment intelligence and blockchain analytics to help financial institutions identify fraud, scams, sanctions exposure, and other financial crime indicators throughout the stablecoin payment process.
The system operates through a platform-agnostic application programming interface (API), examining transaction context, the origin of funds, restricted-party exposure, and potential scam indicators. The payments giant Mastercard explained that it produces risk scores before payments are completed, allowing banks and payment providers to investigate suspicious activity before settlement.
“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. Johnson added that combining conventional payment data with blockchain intelligence gives institutions greater visibility into digital asset transactions and their associated risks.
The challenge is hardly theoretical. Mastercard cited research examining 593 million stablecoin transfer events across 141 million Ethereum transactions in 2025. Nearly 60% involved complex, multistep activity rather than straightforward transfers between two parties. That complexity can leave banks struggling to understand precisely where funds originated, which intermediaries handled them, and whether suspicious activity occurred along the way.
Mastercard illustrated the system with a Boston coffee shop purchasing beans from a Brazilian supplier. Before the bank facilitates a stablecoin payment , its service provider can evaluate the transaction’s risk indicators and determine whether additional scrutiny is warranted. The supplier ultimately receives payment and converts the stablecoins into local currency, while the bank gains an additional layer of transaction intelligence.
Mastercard has enlisted Borderless.xyz and Keyrails, two participants in its Start Path Blockchain and Digital Assets program, to introduce the technology into cross-border payment operations. Borderless.xyz connects financial institutions with licensed stablecoin providers across more than 113 countries and 72 currencies. Keyrails concentrates on high-value international trade payments, particularly in emerging markets.
“Global trade needs trusted infrastructure for stablecoin settlement,” remarked Rajpal Khangura, Keyrails’ co-founder and chief compliance officer, in a statement.
The initial rollout focuses on North America, with Mastercard targeting worldwide commercial availability in 2027. Its recently acquired stablecoin infrastructure company, BVNK , is also expected to support the expansion.
Mastercard’s latest offering follows more than a decade of blockchain experimentation. The company introduced a permissioned blockchain network in 2017, expanded cryptocurrency card partnerships in 2020, and announced plans to support selected digital currencies in 2021. It subsequently introduced Crypto Source in 2022, Mastercard Crypto Credential in 2023, and expanded stablecoin settlement capabilities during 2025 and 2026.
The company upped the ante this year, acquiring BVNK in August and introducing its Global Money Platform on Oct. 15 , just four days before unveiling Stablecoin Security. Those developments put Mastercard deeper into stablecoin infrastructure, from moving and converting digital dollars to assessing the risks accompanying them.
Yet the latest product introduces an important distinction. Stablecoin payments may settle on decentralized networks, but Mastercard is betting that financial institutions will still want centralized intelligence before allowing those transactions to proceed.
