Solana Partners with Toss Bank to Accelerate Blockchain-Based Cross-Border Payment Innovation
The agreement is a memorandum of understanding (MoU signed in Seoul on June 19 and disclosed on June 22. It establishes a phased proof-of-concept (PoC), meaning the initiative is still a technical pilot and not yet a consumer-facing product or service.
Although still at an early stage, the project is significant because it aims to address the high hidden costs in traditional banking systems. Cross-border transfers through correspondent banking networks typically take several days and incur fees at each intermediary bank involved in the transaction chain.
By leveraging stablecoins on the Solana network, Toss Bank is testing whether transactions can be executed without relying on intermediary banks. If successful, settlement could be completed within seconds, with more transparent costs compared to conventional systems.
Toss Bank selected Solana due to its high transaction throughput, low fees, and fast finality. These characteristics are seen as a solution to the limitations of traditional payment settlement systems, which are often slow and inefficient.
The first phase of the project focuses on testing the technical feasibility of stablecoin transfers. In later stages, Toss Bank plans to engage overseas partners while ensuring regulatory compliance, including Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements.
This initiative also builds on Toss’s remittance service launched in January, which currently supports seven currencies across 30 countries. The addition of blockchain technology is aimed at addressing inefficiencies in cross-border transfers, rather than simply adding a new feature.
South Korean Banking Sector Moves Toward Blockchain
Toss Bank is not alone in exploring blockchain-based payment solutions. KBank is also running a remittance pilot using Ripple’s Palisade infrastructure to test stablecoin transfers to the United Arab Emirates and Thailand.
Meanwhile, KB Financial has tested won-based stablecoin remittances to Vietnam. The pilot reportedly achieved settlement times of under three minutes and reduced fees by around 87%.
The shift is also visible in the payments sector. Shinhan Card has signed an MoU with the Solana Foundation to test stablecoin payments on Solana’s testnet. In total, nine card issuers in South Korea are currently running stablecoin pilot programs.
The growing number of banks and card companies adopting blockchain for cross-border payments suggests that South Korea’s financial industry is gradually moving toward a digital asset-based payment system, rather than isolated experiments.
Driven by Regulatory Developments
The pilot is taking place alongside South Korea’s upcoming digital asset regulations, expected to take effect in December. The framework includes a licensing regime for cross-border virtual asset transfer services.
Toss Bank stated that it will develop the project in line with domestic regulatory changes. This indicates a compliance-first approach, with testing conducted within the boundaries of upcoming legal frameworks before full commercial licensing.
However, the project remains in the testing phase. There is still no official launch timeline, and details such as the stablecoin type, payment corridors, and rollout schedule have not yet been disclosed.
Ultimately, the success of the initiative will depend on whether Toss Bank can meet regulatory requirements in South Korea, demonstrate real-world cost and speed advantages, and integrate the technology into its existing services.
For users who regularly send money abroad, this project does not yet have an immediate impact. However, it signals a broader shift in the banking industry toward faster, cheaper, and more efficient cross-border payments using blockchain technology. Whether Toss Bank’s pilot can fully deliver on this promise remains to be seen, but the move by a bank serving around 15 million users shows that blockchain infrastructure is increasingly being considered part of mainstream financial systems.
