South Korea Super-App Toss to Run Won Stablecoin Pilot on OP Stack |…

Toss, South Korea's 30-million-user fintech super-app, is running a three-month pilot of a Korean won stablecoin on Optimism's OP Stack, with privacy tools from Sunnyside Labs to shield transaction data whilst maintaining compliance. This is the fourth regulated financial institution in a year to adopt OP Stack, after Bitpanda, Kraken and Mitsui, signalling institutional confidence in the framework for regulated digital currencies. If you're building compliance or privacy tooling for regulated finance, you now have proof that a 30-million-user institution will buy it. Toss's three-month pilot is a live reference customer for whoever can solve transaction privacy on public chains without breaking KYC.
