South Korea’s Toss Bank has signed a strategic memorandum of understanding with the Solana Foundation to test blockchain-based remittance and settlement infrastructure, starting with a proof of concept for stablecoin-powered overseas transfers.
The agreement was signed in Seoul on June 19 and announced on June 22. Toss Bank described it as the first direct strategic cooperation agreement between a South Korean internet-only bank and the Solana Foundation.
The first phase will test whether stablecoin transfers on Solana can fit into existing remittance workflows. Toss Bank will handle the banking-service and user-experience side of the trial, while Solana provides the blockchain infrastructure for faster settlement and lower-cost cross-border payment flows.
The partnership gives Solana another regulated-finance foothold in South Korea, where banks, securities firms, and fintech platforms are testing tokenized assets, digital bonds, stablecoin payments, and blockchain settlement rails. Toss Bank serves about 15 million customers, giving the PoC a large potential distribution base if the bank later moves beyond testing.
Stablecoins Sit At The Center Of The Test
The initial work will focus on Solana-based global remittance and settlement infrastructure. Later phases are expected to review payment and settlement models, digital-asset services, tokenized assets, and potential stablecoin use cases.
Toss Bank already operates an overseas remittance product launched in January. The service supports 30 countries and seven major currencies, with real-time tracking and sub-hour transfers for some currencies, including euros, Singapore dollars, and pounds. The Solana trial would test whether blockchain infrastructure can reduce friction further by moving value through stablecoin rails rather than relying only on traditional correspondent banking and settlement windows.
The company is not launching a live consumer stablecoin remittance product yet. The confirmed step is a technical and operational PoC. Future work is expected to include overseas partner integration, anti-money-laundering controls, customer verification, and domestic regulatory alignment before any broader rollout.
The South Korean market is moving in the same direction. KB Kookmin Bank recently issued South Korea’s first bank digital dollar bond, while other local financial firms have been testing blockchain rails for tokenized finance and settlement.
Solana’s Payment Push Keeps Expanding
The Toss Bank deal adds to Solana’s wider payments and settlement campaign. Mastercard recently brought always-on stablecoin settlement to Solana, giving card-network customers a blockchain-based route for 24/7 tokenized-money movement.
That payments narrative has become one of Solana’s strongest institutional angles. Its low fees and fast confirmation times make the network attractive for remittance pilots, stablecoin transfers, merchant settlement, tokenized assets, and financial-market infrastructure tests. The challenge is no longer only whether Solana can move transactions quickly. Banks need compliance controls, liquidity depth, auditability, custody standards, sanctions screening, and clear legal treatment for the stablecoins used in settlement.
Cross-border payments remain one of the clearest commercial targets for blockchain finance. Ripple’s recent stake in Flutterwave showed how major crypto-payment firms are still chasing remittance and merchant corridors, especially where traditional rails remain expensive or slow.
The signed MOU keeps the project at proof-of-concept stage for now, but it gives Toss Bank a direct Solana testing lane for stablecoin remittances as South Korean financial firms move deeper into blockchain-based settlement.
