#MastercardStablecoinCards Kima joins Mastercard sandbox to enable stablecoin card top-ups

Decentralized settlement protocol Kima has integrated into Mastercard’s sandbox program, enabling stablecoin-powered top-ups for prepaid cards directly from self-custody wallets.

According to an announcement shared with Cointelegraph, Mastercard partners can now rely on Kima’s settlement infrastructure to enable their prepaid cards to be topped up with stablecoins, including USDC (USDC) and Tether’s USDt (USDT), from self-custody wallets across more than 10 blockchains.

Kima CEO Eitan Katz said the integration shows that stablecoins can be practical for everyday use, removing friction and intermediaries from crypto-to-fiat conversions while expanding crypto usability.

“Our goal at Kima is to eliminate barriers between digital assets and traditional finance,” Katz said.

Infrastructure designed for interoperability

Katz described Kima’s settlement system as asset-agnostic and designed to simplify cross-ecosystem payments, supporting public blockchains, private ledgers and traditional banking rails:

“Kima’s asset-agnostic settlement layer is designed to abstract the complexity of transferring value across disparate ecosystems, whether that’s public blockchains, private ledgers, or even traditional banking systems.”

According to the announcement, Kima’s infrastructure is aligned with Mastercard’s aim to bring stablecoins into mainstream financial usage. Katz rejects the Bitcoin and crypto hardliner vision of digital assets being contraposed to fiat currency, claiming that “crypto and fiat must coexist seamlessly to reach their full potential.”

Katz explained that Kima’s solution allows easy crosschain interoperability and eliminates reliance on intermediaries, custodians or complex smart contracts. This, in turn, reportedly enhances security and efficiency for all parties involved.
