Kima has joined Mastercard's sandbox program to support prepaid card top-ups using stablecoins. Users can directly top up with stablecoins such as $USDC and USDT from self-custody wallets, covering more than 10 blockchains. Kima CEO Eitan Katz stated that this move demonstrates the practicality of stablecoins in everyday use, reducing friction and intermediaries in the conversion between cryptocurrencies and fiat currencies, thereby enhancing the usability of cryptocurrencies. Kima's settlement system is asset-agnostic, supporting cross-ecosystem payments, including public blockchains, private ledgers, and traditional banking systems, aiming to simplify value transfer. This infrastructure aligns with Mastercard's goal of promoting stablecoins into mainstream finance. Kima has also been included by the European Central Bank in its Digital Euro Innovation Partnership list, participating in exploring digital euro payment functions and use cases. Katz emphasized that compliance should not come at the cost of relinquishing control over funds and data; users retain full control over their keys, and compliance checks are conducted by third-party institutions to ensure security and efficiency.
