Mastercard launches Stablecoin Security to give banks a risk score before stablecoin payments move

Summary

Mastercard announced Stablecoin Security at Money20/20 USA on Monday, a risk-intelligence service that combines payment and blockchain data to flag fraud, scams, sanctions and other financial-crime risks in stablecoin payments, including before funds move onchain, according to the company’s release.

Delivered through an API, the service looks at transaction context, where funds came from, exposure to restricted parties and scam indicators, and produces a risk score before a payment is completed that banks can plug into existing fraud and compliance systems, Mastercard, The Block and PYMNTS said.

Borderless.xyz and Keyrails are the first partners; Mastercard plans to launch first in North America and expects worldwide commercial availability in 2027.

The Block and PYMNTS said Mastercard plans to bring BVNK, the stablecoin infrastructure firm it acquired in August, into the effort next year.
