KBank, South Korea's prominent digital-only bank and exclusive banking partner for the crypto exchange Upbit, has announced plans to test on-chain cross-border remittances in collaboration with Ripple. The two companies have successfully completed the first phase of a proof-of-concept using a wallet-based remittance system and are now proceeding to the second phase, which involves testing the stability of on-chain transfers to countries such as the United Arab Emirates and Thailand. KBank is utilizing Palisade, Ripple's software-as-a-service wallet acquired as part of Ripple's $4 billion investment in crypto-related ventures.
Traditional international bank transfers often rely on correspondent banking networks like SWIFT, which can take several days to settle and incur significant fees at each intermediary. In contrast, on-chain remittances enable direct fund transfers across a blockchain network, settling in minutes with fees paid only to the network.
The partnership between KBank and Ripple aims to assess the potential of this approach in improving speed, cost, and transparency for remittance customers. Additionally, KBank is preparing for impending stablecoin regulations in Korea by conducting technical verification of remittance use cases for stablecoins as the regulatory framework develops. The Korean government requires all crypto exchange users to link a verified bank account before trading, with each major exchange paired exclusively with one bank. KBank holds a monopoly position with Upbit, the country's largest crypto exchange, which has contributed to its user base growth from approximately 2 million in 2020 to 15 million by the end of 2025.
As South Korean lawmakers finalize the Digital Asset Basic Act, a comprehensive crypto regulatory framework, major financial institutions in the country are signing infrastructure deals with global blockchain companies. Korea boasts one of the most active retail crypto markets worldwide, with daily trading volumes on local exchanges often surpassing those of mainstream stocks during peak periods. Banks operating in this market are positioning themselves to handle the anticipated corporate and cross-border activity once the Digital Asset Basic Act formalizes the treatment of stablecoins, custody, and tokenized assets under Korean law.
