South Korea's Toss Bank has partnered with the Solana Foundation to build a blockchain-based financial infrastructure on Solana, focused on a proof-of-concept for overseas remittances and stablecoin payments. The two will work on a settlement layer that can move value across borders using stablecoins, with Toss Bank's retail base and the Solana network's throughput the stated foundations of the test.
Why it matters
Toss Bank is the digital banking arm of Viva Republica, the operator of Toss, the payments super-app that dominates Korean consumer finance. A top-tier incumbent choosing to build on Solana rather than a domestic chain or a permissioned bank consortium is a meaningful endorsement for a public network that has spent two years rebuilding institutional trust after the FTX collapse. It also gives the stablecoin remittance thesis a concrete Asia-Pacific corridor to test in, a market where retail cross-border flows are large and incumbent rails are expensive.
Market impact
The PoC puts Solana directly into a regulated banking workflow for the first time at meaningful Korean retail scale, an integration the SOL ecosystem has lacked since the DeFi summer peak. Watch the announcement for settlement currency, corridor partners, and whether the pilot graduates to live customer traffic in 2026.
