What Toss Bank does

Toss Bank is South Korea's third-largest internet-only bank, launched in 2021 as a wholly-owned subsidiary of Viva Republica, operator of the Toss super-app ecosystem. The bank serves approximately 15 million retail customers through a mobile-first, branchless distribution model embedded within the Toss super-app, which has approximately 30 million registered users across South Korea. Its product portfolio spans deposit accounts (personal, business, group, children's, and corporate), savings products with gamification features (Keyword Savings, Gulbi Savings, prenatal and children's savings), personal and business loans (including Korea's first fully digital business loan from an internet-only bank), multi-currency foreign exchange across 17 currencies, international remittance to 30+ countries, and checkcards plus co-branded credit cards issued with Hana Card. The bank also maintains a single physical support center in Yeoksam, Seoul.

The bank's technology stack is cloud-native and mobile-first, anchored by an ML-powered Fraud Detection System (FDS) with 24/7 monitoring and the proprietary Siren Alert system that has prevented 3,255 billion KRW in customer fraud damages. Alternative credit scoring models leverage non-financial data (mobile bills, utility payments, spending patterns) to underwrite thin-file borrowers underserved by traditional banks. An internally developed Helpdesk customer support system unified inquiries, corporate support, delinquency, and phone response into a single interface, delivering 32% improvement in support quality, 56% faster chat resolution, and 26% faster call handling. Toss Bank is currently piloting Solana blockchain infrastructure for stablecoin-based cross-border remittances under a June 2026 MOU with the Solana Foundation, the first such direct partnership between a Korean internet-only bank and the foundation.

Toss Bank generates revenue primarily through net interest income on loans (credit, mortgage-prep, jeonse, business) and deposits, supplemented by transaction-based fees from card interchange, foreign exchange (100% markup with zero commission on 17 currencies), overseas remittance (as low as 3,900 KRW per transaction), and insurance products including jeonse deposit protection. The bank became profitable in July 2023 and reported 96.8 billion KRW in net profit in 2025, with capital adequacy around 13%. Toss Bank has raised approximately 1.935 trillion KRW in paid-in capital through multiple rounds, with its standalone valuation at 2.4 trillion KRW as of September 2023. Parent Viva Republica is valued at 20.5 trillion KRW following a January 2026 share swap with China's Ant Group and is preparing for a Nasdaq IPO targeting over $10 billion.
