Mastercard unveils tool to secure stablecoin payments

The product, called Stablecoin Security, was announced at the Money20/20 USA conference. It runs as an API that plugs into a bank’s existing compliance systems, analyzes where funds came from, what the transaction involves, and any links to financial crime, then returns a risk score for each payment. Borderless.xyz and Keyrails are the first named partners, and the service starts with institutions handling cross-border stablecoin payments.

Why Mastercard Is Scoring Transfers Before They Settle

Mastercard points to the messiness of stablecoin transfers as the main reason for the tool. A BIS study counted 593 million stablecoin transfers across 141 million Ethereum transactions in 2025, and nearly 60% of those were complex, multi-step transactions. That layering makes suspicious activity harder for institutions to spot.

Ann Johnson, Mastercard’s executive vice president of Security Solutions, framed it as a confidence problem. Stablecoins are creating new possibilities for value exchange, but financial institutions need the right intelligence and controls to participate with confidence, she said.

Rollout Starts in North America

The launch follows a run of crypto-focused moves from the company:

• A partnership with BVNK on a Global Money Platform that combines traditional and digital currency services through a single API
• Work with SoFi to support SoFiUSD settlement across the Mastercard card network

Stablecoin Security launches first in North America, with worldwide commercial availability expected by 2027. Mastercard also plans to integrate BVNK into the service next year.

Hashlytics Take

The detail that matters is timing. A blockchain payment is hard to reverse once it settles, so a risk score returned before finality is the only point where a bank can still say no. That makes this less a fraud tool than a way for Mastercard to position itself as the compliance checkpoint that stablecoin rails currently lack. The BIS figure supports the pitch, but the announcement leaves out how accurate the scoring is and what it costs, and two named partners is a thin launch list. Banks will decide whether this becomes standard infrastructure, and for now that is still unproven.
