South Korea's internet-only K Bank, which serves as a banking partner for Upbit, has announced a strategic partnership with Ripple to conduct a proof of concept (PoC) for on-chain cross-border remittances. According to multiple local media reports, the deal was closed between K-Bank CEO Choi Woo-hyung and Ripple Asia Pacific (APAC) Head Fiona Murray on April 27, 2026 at the bank's headquarters in Seoul. Through this partnership, K Bank plans to use Ripple's blockchain infrastructure and global network to assess whether the technology can improve the speed, cost efficiency, and transparency of its remittance services. The companies have already completed the first phase of the PoC, which involved verifying a wallet app-based remittance system, with the second phase currently underway testing the stability of on-chain remittances in a virtual environment. The partnership may expand to support KBank's live cross-border remittance system and additional digital asset initiatives, with no timeline for live deployment confirmed.
The implementation requires technical verification in two phases. As reported by multiple sources, the first round of verification has already been completed, analyzing the 'separate app-based remittance structure.' The second verification round is currently in progress, where both K Bank and Ripple will test the stability of on-chain remittances in a virtual environment, including transfers to countries such as the UAE and Thailand. For the second phase, KBank is using Ripple's Palisade software-as-a-service wallet application, which was acquired in November 2025 and already meets international security standards. The Palisade platform offers institutional-grade security features including Multi-Party Computation (MPC) and zero-trust architecture, along with fast wallet provisioning, multi-chain compatibility, and DeFi integration. The project will continue through technical testing with Ripple's wallet infrastructure and K Bank's internal systems, assessing transaction stability, payment flow, compliance readiness, and potential deployment models.
The blockchain remittance model operates through a simple customer interface where K Bank users see their balance in Korean won and choose to send money to recipients in either the UAE or Thailand. Behind the scenes, the bank converts won into a stablecoin in the background, sends it across Ripple's blockchain network, and converts it back into local currency on the other end. According to recent reports, Korea hosts more than 180,000 Thai nationals who regularly send money home, making the Korea-Thailand route a significant test of demand. K Bank has also filed 13 trademark applications related to stablecoin wallets earlier this year, with names including KSC Wallet, KSTA Wallet, and Kstable Wallet, suggesting the bank is building infrastructure well beyond basic banking services. The bank also targeted a listing on the KOSPI exchange in early 2026, positioning it for future expansion in digital asset services. K Bank has signed a memorandum of understanding in both markets for stablecoin-based transactions, with the latest phase testing on-chain transactions with partners in the UAE and Thailand.
The partnership addresses significant cost and speed advantages over traditional banking methods. As reported by recent analysis, sending money through traditional correspondent banks takes 1-3 business days and costs roughly 5-8% on Asia-to-Asia routes, while stablecoin transfers settle in seconds and cost cents on the blockchain side. This model allows K Bank to pass most savings to customers and the bank itself. The trial does not mean K Bank has launched a full blockchain remittance product - the current work remains at the proof-of-concept stage. However, the second phase moves testing closer to account-linked systems and partner-based international transfers. The pilot targets remittance corridors to the United Arab Emirates and Thailand, where traditional SWIFT-based transfers involve multiple intermediary banks that add fees and processing time. Onchain remittances aim to eliminate these layers by settling directly on a blockchain network, with transfer fees going only to the network itself rather than correspondent banks.
The partnership announcement coincides with broader developments in South Korea's blockchain ecosystem. According to Tiger Research's recent report, the number of verified users in South Korea reached 11.33 million by the end of 2025, marking an all-time high. K Bank is the sole banking partner for Upbit, South Korea's largest crypto exchange, with all Upbit users required to open an account with KBank to trade fiat currency for crypto. This relationship contributed to KBank's user base growing from around 2 million in 2020 to 15 million by the end of last year. The K Bank-Ripple PoC specifically uses stablecoins as settlement assets rather than XRP, as banks prefer predictable settlement value over XRP's volatility. The partnership is part of a broader wave of deals between South Korean financial institutions and global blockchain firms ahead of the country's upcoming Digital Asset Basic Act, a comprehensive regulatory framework for cryptocurrencies. Earlier this month, Ripple also partnered with Kyobo Life Insurance for tokenized government bond transactions conducted through Ripple Custody, demonstrating the growing momentum in South Korea's blockchain adoption.
