Solana Foundation and Toss Bank Sign MOU to Rebuild Korean Remittance Rails

Solana News: The Solana Foundation and Toss Bank signed a Memorandum of Understanding, marking the first direct partnership between a South Korean internet-only bank and the Solana ecosystem, and positioning the deal squarely inside parent company Viva Republica’s pre-IPO technology narrative.

SOL sitting at $74 on the announcement, with trading volume rising 8% over 24 hours, though concurrent US-Iran peace talk developments complicate clean attribution of that volume spike to the MOU alone.

Toss Bank serves 15 million customers across South Korea as the country’s third-largest internet-only bank, and its overseas remittance service already covers 30 countries and 7 major currencies.

That existing footprint gives the Solana-based proof of concept a non-trivial addressable base from day one; this is not a greenfield experiment.

Solana News: MOU Scope, Four Workstreams, One Live PoC

The MOU covers four areas: a proof of concept for global remittance and settlement infrastructure built on Solana; joint research into blockchain-based payment and settlement models; exploration of stablecoin and digital asset financial services; and a longer-term cooperation framework that includes integration with overseas banking partners and AML/KYC compliance systems.

The immediate live work is the PoC, everything downstream of that depends on what it produces.

Jin-hyun Park, head of strategy at Toss Bank, said the partnership launches “a phased pilot within the innovative services already provided by Toss Bank,” with the stated goal of delivering “quicker and more economical global digital finance through Solana” to its 15 million customers.

The framing is deliberate: this is positioned as an upgrade to existing infrastructure, not a speculative pivot into crypto.

Solana’s technical case here is straightforward: sub-second finality and transaction fees measured in fractions of a cent make it a credible rail for high-volume cross-border settlement, where SWIFT-era correspondent banking costs are the baseline to beat.

The tokenization roadmap comes later, contingent on PoC outcomes and regulatory clearance. An MOU is a narrative event; live PoC results are execution events. The market will need to see the latter before the former carries durable weight.

The Solana Foundation had already been building Korean institutional infrastructure before this deal. A separate MOU with local firm Wavebridge targets a KRW-pegged stablecoin designed to be “issued, validated, regulated, and suitable for institutional applications,” with on-chain settlement and tokenized deposit functionality involving major Korean banks. The Toss Bank partnership slots into that broader Korea strategy rather than standing alone.

Why the Solana Bet Lands Now: Viva Republica’s $10B IPO Play

Viva Republica, the parent company behind Toss Bank and the broader Toss super-app ecosystem, is targeting a US IPO in 2026 at a valuation exceeding $10 billion.

The firm has raised over $1.2 billion from investors, including GIC, Sequoia China, and Kleiner Perkins, and boosted Toss Bank’s paid-in capital to roughly 1.4 trillion won (~$1 billion) across six funding rounds to support growth and listing readiness.

The Solana MOU serves three functions in that IPO story. First, it reframes Viva Republica as a cross-border payments platform tapping a projected $320 trillion global payments market, not merely a domestic Korean neobank, which commands a tighter multiple on a US exchange. Second, the compliance-first architecture (AML/KYC integration, bank license, regulated stablecoin rails) places Toss in the regulated-innovator category rather than alongside unregulated crypto firms, a meaningful distinction for US institutional allocators.

Third, blockchain settlement rails lower marginal cost per remittance transaction, supporting the margin expansion narrative that pre-IPO models need.

This is legitimate strategic positioning, not window dressing, but the distinction between a partnership announcement and shipped infrastructure matters for any investor reading the prospectus. Viva Republica is telling a story that the PoC needs to eventually validate.

The regulatory context adds urgency. South Korea plans to impose foreign exchange controls on crypto transfers starting December 2026.

Toss Bank moving now, via a licensed, compliance-integrated framework, positions it ahead of that cutoff rather than scrambling to retrofit after the rules land. The Bank of Korea’s concurrent wholesale CBDC and tokenized deposit pilot with 100,000 users provides the policy backdrop that makes a bank-grade stablecoin remittance product politically viable rather than speculative.
