The SDK connects non-custodial wallets to banking systems, maintaining compliance with anti-money laundering(AML) and know-your-customer(KYC) requirements.The system uses Kima’s Universal Payment Rail, a decentralized infrastructure that supports real-time financial transfers between blockchain assets and bank accounts. Transactions are completed through a secure, peer-to-peer process.Real-World Use Case with PaiOne of the initial deployments of this system involved Pai, a prepaid card issuer.

This reduced operational costs and increased scalability for Pai’s card offerings.The system also ensured regulatory alignment by incorporating built-in compliance features. As a result, Pai expanded market access and provided more flexible services for users handling digital assets.Demonstration and Institutional AccessKima’s solution is available for demonstration within the Mastercard Sandbox. The simulation includes selecting blockchain networks, connecting wallets, and executing top-ups for a virtual Mastercard prepaid card. The system supports stablecoins pegged to USD and EUR, ensuring currency interoperability.The technology seeks to serve a wide sectors, including neo banks, remittance firms, payroll services, and decentralized applications.
