In brief Mastercard launched Stablecoin Security, a risk-intelligence tool that lets financial institutions screen stablecoin payments for fraud, scams and sanctions exposure across the transaction lifecycle, generating a risk score before a payment settles. It extends Mastercard’s stablecoin push—from its BVNK-powered Global Money Platform to AI-agent payments—launching first in North America, with global availability in 2027.

Mastercard is extending its fraud-fighting playbook to stablecoins, launching a tool that lets financial institutions scan dollar-pegged token payments for fraud, scams, and sanctions exposure before the money ever moves on-chain. Unveiled Monday at the Money20/20 conference in Las Vegas, the product, called Stablecoin Security, combines Mastercard’s payment intelligence with blockchain analytics to assess risk across the full life of a transaction, from the moment a payment is initiated through its movement on a public ledger.

The company launched it with two initial program participants, Borderless.xyz and Keyrails, both alumni of its Start Path blockchain accelerator. Mastercard cited a Bank for International Settlements study of 593 million stablecoin transfers in 2025 that found nearly 60% were complex, multi-step transactions rather than simple one-to-one payments, making it harder for institutions to gauge risk across the whole journey.
