Kbank, South Korea’s first internet‑only bank, has chosen Ripple’s institutional custody platform to power its digital asset wallets. The bank will deploy Ripple Custody as core wallet infrastructure to manage digital assets across multiple blockchains within a regulated environment.
Kbank already serves as the exclusive banking partner to Upbit, the country’s largest crypto exchange, which makes it one of Korea’s most crypto‑native banks. By adding Ripple’s custody stack, the bank aims to upgrade how it safeguards and operates digital assets for current and future services.
How Ripple Custody Supports Kbank
Ripple Custody, built on multi‑party computation (MPC) technology, offers fast wallet provisioning, high‑speed transaction signing, and granular security controls for institutions. Instead of building its own wallet infrastructure from scratch, Kbank will use Ripple’s wallet‑as‑a‑service model to get bank‑grade custody with governance and compliance tools baked in.
Ripple says this setup lets regulated banks scale digital asset services without taking on the full cost and operational risk of running bespoke custody systems. For Kbank, that means it can move faster on new blockchain products while still meeting security and oversight expectations in Korea’s tightly watched financial sector.
Tied to Kbank’s Remittance and Stablecoin Plans
The custody deal sits alongside Kbank’s ongoing work with Ripple on blockchain‑based cross‑border remittances using Ripple’s Palisade wallet. Kbank and Ripple are testing wallet‑based transfers to markets such as the UAE and Thailand, aiming to improve speed, costs, and transparency versus existing overseas remittance rails.
Kbank CEO Choi Woo‑hyung has said the partnership marks a turning point for the bank’s stablecoin‑based remittance ambitions and its broader digital finance roadmap. By pairing Ripple Custody’s secure wallet infrastructure with on‑chain remittance proof-of-concept solutions, Kbank is positioning itself to launch more production‑grade blockchain services once Korea’s digital asset rules fully settle.
Ripple’s deal with Kbank is its first bank‑grade wallet deployment with a Korean internet‑only lender and follows earlier custody work with other regional institutions. For Ripple, it strengthens a growing base in Asia for RLUSD, XRP, and other tokenized assets that require institutional‑grade storage.
Kbank’s choice suggests that partnering for custody may be more practical than building from the ground up. If the rollout goes smoothly and Korea finalizes its Digital Asset Basic Act as planned, more local lenders could follow Kbank’s model of combining third‑party wallet infrastructure with in‑house product design.
