Toss Bank of South Korea has signed an agreement with the Solana Foundation to test a blockchain-based financial infrastructure designed to improve cross-border payments and remittances. The initiative will focus on building a proof-of-concept using stablecoins on the Solana network.
The project marks one of the first attempts by a regulated bank with around 15 million customers to apply a public blockchain to core banking functions such as international transfers.
Initial testing of stablecoin remittances
The rollout will begin with technical validation of stablecoin-powered remittances. Toss Bank plans to integrate its existing financial systems into the blockchain environment and evaluate performance, transaction efficiency, and compliance mechanisms.
The bank said it will closely assess anti-money laundering standards and identity verification systems during this phase to ensure the infrastructure meets regulatory requirements.
Expansion to global payment trials
Following initial validation, Toss Bank intends to conduct trials with overseas partners. These tests will focus on operational reliability and transaction security before any broader rollout.
The bank already supports remittances across 30 countries and seven major currencies, and the new system is expected to enhance speed and reduce costs in those corridors.
Broader digital finance ambitions
Park, head of strategy at Toss Bank, said the agreement signals a new phase in developing digital banking infrastructure aligned with emerging technologies. Beyond payments, the bank plans to explore applications involving digital assets and tokenized financial services.
The Solana Foundation has previously worked with other Korean financial firms, including Shinhan Card and Hanwha Asset Management, on similar early-stage blockchain projects as regulatory frameworks continue to evolve.
Timing aligned with regulation
The initiative comes as South Korea advances its “Digital Assets Second Phase Act,” which is expected to introduce clearer rules for stablecoins within the year. Toss Bank said it will adapt its efforts in line with the upcoming regulatory framework.
The scale of the opportunity is significant. The global remittance market is projected to reach about $879 billion in 2026, with demand driven by faster and lower-cost digital transfers.
Market implications and network performance
For traders watching the sector, the proof-of-concept phase will offer a practical benchmark for how blockchain performs in a regulated banking setting. Results from technical and compliance testing will likely determine whether the project advances to full deployment.
Attention will also be on Solana’s network stability under institutional use. The network has reported processing more than 100 million daily transactions and hosting millions of active users, along with a sizable stablecoin ecosystem.
Any formal guidance from South Korea’s Financial Services Commission could act as a catalyst, potentially moving the initiative from testing into a live financial service.
