Web3 Payments Go Offline: Shinhan Card's Pilot - OneSafe.io
On October 27, 2026, Shinhan Card announced an offline crypto payment pilot with Dunamu using the Kiya Chain and Kiya Wallet, marking the first time a South Korean card company has tested this setup in a real payment environment.
The test will use a proprietary token issued on Kiya Chain to process employee payments at a merchant inside Shinhan Card's headquarters, with Dunamu supporting the blockchain network. This represents a significant shift from typical crypto payment models, as the card issuer is managing the token, wallet support, and merchant relationship rather than relying on peer-to-peer transactions.
Why this matters
Most Web3 payment systems assume crypto-native merchants with wallets or gateways. Shinhan's pilot changes that frame by demonstrating how card issuers can manage blockchain payments. If this approach scales, businesses might accept Web3 payments without separate crypto gateways, moving closer to the traditional card-network model but with different settlement and custody risks.
The back-office implications are particularly significant. A blockchain-based card payment still requires reconciliation, taxation, and recording. For global businesses or DAOs operating a fiat crypto payment stack, this raises practical questions about handling token-denominated transactions that settle to crypto wallets while payroll runs in fiat or stablecoins.
Offline acceptance challenge
Most crypto payment infrastructure handles online checkout, but physical point-of-sale demands offline authorization, terminal integration, speed, and dispute handling. Shinhan's pilot tests a proprietary token inside a digital wallet specifically for offline crypto payments, addressing the missing last mile for widespread Web3 adoption beyond e-commerce.
Operational requirements
A reliable fiat crypto payment stack needs corporate cards with spend limits, multi-currency crypto accounts, invoicing capabilities for fiat or stablecoins, and automated settlement. Without proper controls, employee payment pilots can quickly become uncontrolled when expanded to contractors or vendors.
Reconciliation across fiat and crypto ledgers remains the biggest operational challenge. A transaction on a public blockchain may be final in seconds, but that doesn't automatically map it to invoices, settlement files, token valuations, and bank statements. Without a single ledger view, businesses create shadow ledgers that create compliance risks.
What's next
Shinhan Card plans to gradually expand participating merchants and link with global blockchain networks. The key questions to watch are whether the pilot moves beyond employees to public customers, and whether Kiya Chain connects to other networks or stablecoin standards. Regulatory developments like the OCC's stablecoin move and the GENIUS Act update from October 2026 will also shape the commercial viability of such systems.
