Mastercard has unveiled Stablecoin Security, a risk-scoring tool designed to help financial institutions evaluate stablecoin payments before and during their movement across blockchains. The product, introduced at Money20/20 in Las Vegas, combines traditional payment intelligence with blockchain data to assess fraud, sanctions, and scam risks throughout a transfer's journey. By using an API, the service can generate a risk assessment prior to transaction completion, considering factors like payment context, fund origin, and exposure to restricted parties.
Stablecoin transfers are known for their speed, but identifying suspicious activity before it occurs is challenging, especially when transactions cross multiple providers, blockchains, and traditional banking systems. Mastercard's solution aims to bridge this gap by offering a familiar banking control in an evolving payment environment. The company has partnered with Borderless.xyz and Keyrails as initial users, targeting businesses that are adopting stablecoin settlement.
The tool is based on research covering 593 million stablecoin transfer events and 141 million Ethereum transactions in 2025, revealing that nearly 60% of transfers involved complex, multi-step routes. Mastercard plans to launch the service in North America first, with broader availability expected by 2027. While the company does not claim to eliminate fraud, it aims to provide an essential layer of security in the increasingly decentralized payment space.
As stablecoins gain traction, the need for robust risk assessment tools becomes more urgent. Mastercard's initiative underscores the growing importance of integrating traditional financial safeguards with blockchain technology to address emerging compliance and fraud challenges. The tool is positioned as a critical step toward ensuring safer and more transparent stablecoin transactions in a rapidly evolving market.
