Toss, a leading South Korean fintech, is pursuing a native blockchain mainnet and a built‑in token to fuse payments and financial services into one integrated ecosystem, potentially making Korea’s crypto landscape among the most cohesive.

The final network design remains undecided and will hinge on regulatory developments, including South Korea’s Digital Asset Basic Act governing token issuance, stablecoins, and crypto ETFs.

Toss is leveraging its regulatory know‑how to navigate compliance and plan a phased rollout as rules evolve.

A Layer 1 mainnet offers control over fees and governance but requires substantial investment, while Ethereum‑based Layer 2 options could deliver faster initial scalability.

The company is exploring both Layer 1 and Layer 2 approaches, potentially adopting a hybrid model with a primary chain and scalable Layer 2 solutions to boost liquidity and performance.

A phased implementation is envisioned, spanning technical development, regulatory review, pilots, and gradual rollout, with no specific dates yet.

The rollout could unfold in stages: 6–12 months of development and testing, 3–9 months for regulatory review, 3–6 months for pilots, and 6–12 months for broader deployment.

The details originate from Blockmedia, which cites an unnamed Toss source, with The Block seeking comment from Toss.

Overall, Toss is signaling a bold convergence of traditional finance and blockchain within an integrated user‑oriented ecosystem, though timelines and technical specifics are still uncertain.

Toss is weighing a native Layer 1 mainnet and a potential Layer 2 for scalability, but has not settled on which path to pursue.

Since February 2026, Toss has been actively building a blockchain team—hiring for wallet design, node operation, APIs, and cryptographic security—and is developing a Web3 wallet integrated into the Toss app.

The company is recruiting blockchain engineers to support wallet systems, API/transaction processing, node operations, cryptographic signing, and regulatory compliance, with the aim of a seamless in‑app Web3 wallet.
