Solana Partners with Toss Bank on Cross-Border Payment Pilot

Key Takeaways

• Toss Bank signed an MoU with the Solana Foundation to test cross-border remittances.
• The proof-of-concept targets faster, cheaper transfers for its 15 million users.
• Rival KBank is running a parallel pilot on Ripple’s Palisade infrastructure.
• The move arrives as South Korea finalizes new digital asset rules.

The agreement, a memorandum of understanding signed in Seoul on June 19 and disclosed June 22, sets up a phased proof-of-concept rather than a live product. While this is currently a technical pilot, not a consumer feature, it matters because it targets the hidden costs of traditional banking. Cross-border transfers through correspondent banking can take days and stack fees at each intermediary bank along the chain. By using stablecoins on Solana, Toss Bank is testing whether it can bypass those intermediaries entirely, settling value in seconds at a single transparent cost rather than several hidden ones.

The bank chose Solana for its high throughput, low fees, and fast finality, the exact qualities legacy settlement lacks. The first phase tests the technical feasibility of stablecoin transfers, with later stages adding overseas partners and compliance work including anti-money-laundering and know-your-customer checks. It is also an evolution of the remittance service Toss launched in January, which already covers seven currencies across 30 countries; the blockchain layer is an attempt to fix the core inefficiency of moving money internationally, not just add a feature on top.

A Sector-Wide Shift

Toss Bank is not moving alone. Rival KBank is running its own blockchain remittance pilot on Ripple’s Palisade infrastructure, testing stablecoin transfers to the UAE and Thailand, while KB Financial has tested won-stablecoin remittances to Vietnam that reportedly settled in under three minutes and cut fees by around 87%. The pattern extends beyond banks: Shinhan Card has signed its own MoU with the Solana Foundation to test stablecoin payments on Solana’s testnet, one of nine Korean card issuers running stablecoin pilots at the same time. Major Korean banks and card companies moving off legacy rails at once, across different blockchains, signals an industry-wide shift rather than a one-off experiment.

The Regulatory Timing

The timing is not accidental. This work is happening alongside new South Korean digital asset rules expected to take effect in December, including a licensing regime for cross-border virtual asset transfers. Toss Bank said it will advance its plans while responding to those domestic moves, which points to a compliance-first approach: testing within the coming rules rather than ahead of them. That suggests the proof-of-concept doubles as positioning for licensed operations once the framework is finalized.

For now, the caveats matter. This is a feasibility test, not a launched service, with no public launch date, and the stablecoin, corridors, and timeline are still unconfirmed. The open questions are whether it clears Korea’s regulatory bar, proves the cost and speed gains in practice, and fits Toss Bank’s existing services.

What this means for you, if you are among the millions who send money across borders, is not an immediate change but a signal of where banking is heading: toward settlement that could one day make an international transfer feel as fast and cheap as a domestic one. Whether Toss Bank’s pilot delivers that is still to be proven, but a mainstream bank with 15 million users is now willing to test it as real infrastructure.
