South Korean fintech giant Toss is preparing a major expansion into Web3 finance, with plans that include a proprietary blockchain network, a native cryptocurrency, and a Web3 wallet embedded directly into its existing super app. According to a report published by regional blockchain outlet Blockmedia on April 6, 2026, the company, operated by Viva Republica, is evaluating how to bring onchain infrastructure into its payments, banking, and securities ecosystem.
The move is notable because Toss already sits at the center of a large consumer finance platform. The company serves roughly 30 million registered users, a scale that reportedly reaches close to 60% of South Korea’s population. Through a single app, Toss already operates services including Toss Bank, Toss Securities, and Toss Payments. By adding blockchain infrastructure to that stack, the company appears to be positioning itself to control more of the rails behind digital financial services, from transaction processing to application governance.
Mainnet ambitions are real, but the architecture is still undecided
Blockmedia reported that Toss is weighing two technical paths. One option is to build a full Layer 1 blockchain from the ground up. The other is to launch a customized Layer 2 network on top of an existing chain. Sources cited in the report said the internal decision has not yet been finalized, and that regulatory developments in South Korea will likely influence the outcome.
This distinction matters. A standalone Layer 1 would give Toss maximum control over fees, governance rules, and developer standards across its ecosystem. A Layer 2 approach, meanwhile, could allow the company to move faster by relying on an existing blockchain base while tailoring execution and settlement for its own financial applications. Industry experts cited by the report framed the choice as a tradeoff between independence and speed-to-market, although both routes would significantly deepen Toss’s crypto-native capabilities.
Professor Seokjin Hwang of Dongguk University, quoted in the report, argued that an independent infrastructure stack can reduce external dependencies and support broader business scalability. Seungik Yoon of Tiger Research, on the other hand, said that a tailored Layer 2 on a proven network could accelerate tokenization efforts. That debate appears to mirror the strategic crossroads Toss currently faces.
Stablecoin trademarks suggest a broader payments strategy
One of the clearest signs of Toss’s Web3 intentions is its work around stablecoins. A dedicated stablecoin task force led by Chief Business Officer Kyuha Kim is already operating inside the company. In June 2025, Toss registered trademarks for 24 Korean won-denominated stablecoin names, including TOSSKRW.
Those filings do not confirm a launch, but they do indicate that the company has been preparing branding and product pathways for a won-based digital currency strategy. In the context of Toss’s payments-focused ecosystem, stablecoins could eventually play a role in transfers, settlements, programmable disbursements, or tokenized financial products—assuming the regulatory framework permits those use cases.
South Korea’s current legal environment remains a limiting factor. The country has not yet enacted its long-discussed Digital Asset Basic Act, and existing rules around settlement and foreign exchange make stablecoin issuance more complicated. According to the report, Toss has structured its hiring and blockchain planning around compliance readiness, suggesting that legal adaptability is being treated as a core component of the buildout rather than an afterthought.
An integrated Web3 wallet is already in development
Toss also confirmed that it is developing a Web3 wallet that will be integrated directly into its current app, removing the need for a separate download. The wallet is expected to support virtual asset storage, transfers, payments, and management of tokenized securities. That design choice is strategically important: instead of asking users to move into an external crypto product, Toss appears to be bringing blockchain functionality into an interface that millions already use for mainstream financial services.
The company has been hiring blockchain engineers since February 2026, with job listings spanning wallet systems, APIs, transaction processing, node operations, cryptographic signing, and financial compliance. The breadth of these roles suggests Toss is not merely experimenting at the application layer; it is assembling capabilities across both infrastructure and regulated service delivery.
In a company statement cited by the report, a spokesperson said Toss views digital asset-based financial infrastructure as an important area for the future. The firm added that it is actively recruiting people with relevant expertise and broadly considering partnerships with multiple companies, while giving priority to technology acquisition.
“Money 3.0” outlines Toss’s onchain financial vision
At the Seoul Blockchain Meetup 2026 in March, Seo Chang-whoon, head of corporate development at Toss, presented the company’s “Money 3.0” framework. The concept centers on programmable money enabled by smart contracts, borderless finance that operates without restrictions tied to currency, geography, or time, and a stablecoin issuance and distribution model linked to real financial services.
The presentation also included a proof of concept connecting Toss’s small business credit model, SohoScore, with smart contracts for automated lending. That example offered a glimpse into how Toss may be thinking beyond simple wallet or token support. Instead, it suggests an effort to redesign parts of financial intermediation around programmable logic, while still grounding those services in products the company already understands well.
If Toss ultimately controls its own blockchain environment, it could create custom fee structures and service rules suited to lending, payments, and tokenized securities. That would reduce dependence on third-party chains and lower exposure to governance changes made outside the company’s control.
Toss joins a growing race for Korean crypto infrastructure
Toss is not entering an empty field. Other major South Korean crypto-linked firms are also developing their own blockchain infrastructure. Dunamu, the operator of Upbit, is building Kiwachain, an Ethereum Layer 2 network. Hashed is backing Maru, a Layer 1 focused on Korean won stablecoins. What differentiates Toss is the breadth of its consumer finance footprint and the size of its preexisting user base.
That gives the company a potentially powerful distribution advantage. While many blockchain projects must first attract users, Toss already has a massive audience inside a payments and banking interface. If it can convert even a portion of that user base into onchain financial activity, it could accelerate adoption far more efficiently than a standalone crypto-native startup.
The report also noted that Toss is exploring partnerships with KB Financial and Samsung Card as part of its digital asset infrastructure plans. Neither company has publicly commented on those discussions, so the scope and status of any potential collaboration remain unclear.
Strong financial momentum supports long-term investment
Toss’s Web3 push comes as the company strengthens its broader business profile. In 2024, it posted its first annual profit, with consolidated revenue of 1.956 trillion won, or about $1.4 billion, marking a 43% year-over-year increase. The company is also reportedly targeting a U.S. listing in 2026 at a valuation above $10 billion.
Those numbers matter because building blockchain infrastructure is a long-term capital and talent commitment. Toss’s improving financial position gives it more room to invest in engineers, compliance systems, wallet architecture, and possible issuance frameworks for future digital asset products. It also gives investors and partners a clearer signal that the company is approaching Web3 as an extension of a profitable financial platform, not merely as a speculative side project.
No launch date yet, but direction is increasingly clear
For now, Toss has not announced a launch date or technical specifications for its blockchain network. The mainnet plan remains under discussion, and its next steps depend heavily on both regulatory clarity and an internal decision between Layer 1 and Layer 2 architecture.
Still, the broader direction is difficult to miss. Between the stablecoin trademark filings, blockchain hiring push, integrated wallet development, and public articulation of its “Money 3.0” strategy, Toss is laying the groundwork for a serious move into onchain finance. If South Korea’s regulatory environment becomes more defined, the company could emerge as one of the most influential bridges between mainstream fintech and Web3 infrastructure in the region.
