Mastercard Stablecoin Security API lets banks screen fraud and sanctions before on-chain settlement
New tool helps banks identify fraud and sanctions risks in stablecoin payments before funds move on-chain, using combined blockchain and payment data.
Key points
- Mastercard introduced Stablecoin Security with Borderless.xyz and Keyrails as initial partners.
- The solution analyzes transaction context and scam indicators before on-chain settlement occurs.
- It integrates via API into existing fraud and compliance workflows for financial institutions.
Mastercard has announced a new risk intelligence solution called Stablecoin Security. The platform aims to help financial institutions assess risks associated with stablecoin transactions before any funds are moved on-chain.
What happened
Mastercard launched Stablecoin Security, a new risk intelligence solution designed for financial institutions. According to Help Net Security, the company announced Borderless.xyz and Keyrails as initial partners for this program. The solution builds upon Mastercard’s existing security capabilities to address the growing use of stablecoins in cross-border and business-to-business payments. Financial institutions require clearer visibility into risk across complex payment flows, which are becoming increasingly common in global trade.
The tool helps identify indicators of fraud, scams, and sanctions throughout the stablecoin payment lifecycle. It operates before funds move on-chain, allowing for pre-transaction risk assessment. This approach addresses the difficulty institutions face in assessing risk across full payment journeys, including supplier payments and currency exchanges. The solution combines payment intelligence with blockchain analytics to provide a complete view of risk at key transaction points.
Why it matters
A study of 593 million stablecoin transfer events across 141 million Ethereum transactions in 2025 found that nearly 60% were complex, multi-step transactions. According to the report, these were not simple one-to-one payments, making risk assessment harder for institutions. This complexity spans global trade settlement and moving funds across countries and currencies. Stablecoin Security aims to close the gap by integrating data sources.
Ann Johnson, executive vice president of Security Solutions at Mastercard, stated that institutions need the right intelligence to participate with confidence. She noted that the solution extends fraud and risk capabilities to digital asset payments. By bringing payment and blockchain insights together, the tool provides a clearer view of risk. This allows institutions to make more informed decisions and build greater trust in digital asset transactions.
What to watch
- Monitor API integration points for new risk scoring outputs.
- Track changes in how multi-step transactions are flagged.
- Observe updates to sanctions and scam indicator databases.
- Review workflow integration with existing case management systems.
Signals worth monitoring
Teams should examine logs for anomalies in transaction routing patterns. Look for deviations from standard one-to-one payment structures. Check for repeated interactions with known high-risk entities or addresses. Alert on transactions that trigger new risk scores before settlement. Verify that compliance workflows are capturing pre-transaction data correctly. Ensure that blockchain analytics feeds are synchronized with internal payment records. Watch for delays in transaction processing that may indicate manual review queues. Confirm that all integration endpoints are logging detailed context data.
What to do and how to stay safe: Mastercard
- Review current stablecoin transaction monitoring processes for gaps.
- Evaluate API integration requirements for new risk intelligence tools.
- Update compliance workflows to include pre-settlement risk scores.
- Train staff on interpreting complex multi-step transaction data.
