Overview
- Toss has signed an agreement with Optimism and Sunnyside Labs to run a three-month proof‑of‑concept to test a South Korean won‑pegged stablecoin on Optimism’s OP Stack.
- The trial will assess on‑chain settlement mechanics, KYC/AML workflows and data confidentiality to determine whether public chain infrastructure can meet institutional payment standards.
- Sunnyside’s Privacy Boost is intended to keep sensitive transaction details private while still allowing regulated institutions to verify identities and compliance.
- Toss’s network serves about 30 million users and more than 500,000 merchants, so a successful PoC could enable high‑volume, point‑of‑sale on‑chain payments and reduce settlement costs.
- Toss is running parallel blockchain experiments, including talks with the Solana Foundation on remittances, and any commercial rollout will depend on the PoC findings and South Korean regulatory approval.
