“Mastercard Launches Stablecoin Security to Screen Fraud Before Blockchain Payments Settle” — what this page in the network covers. Mastercard has introduced Stablecoin Security, a new risk-scoring tool that lets financial institutions screen stablecoin payments before they are finalized on-chain. Announced at Money20/20 in Las Vegas, the service combines traditional payment intelligence with blockchain data to flag fraud, sanctions, and scam risks across a transfer’s journey. It works via API and can produce a risk assessment before a transaction completes, considering payment context, fund origins, and exposure to restricted parties.
Initial partners include Borderless.xyz and Keyrails. The move addresses a critical gap in stablecoin settlement: while transfers can settle almost instantly, investigating suspicious activity after the fact is difficult, especially when transactions cross multiple providers, blockchains, and banking systems. Mastercard’s research, covering 593 million stablecoin transfer events and 141 million Ethereum transactions in 2025, found that nearly 60% involved complex, multi-step routes rather than simple one-to-one transfers—making pre-transaction screening increasingly valuable.
