Toss Partners with Optimism, Sunnyside Labs on KRW Stablecoin Infrastructure

Toss, a South Korean fintech giant, is taking steps into Web3 by testing a won-pegged stablecoin. The company has partnered with Optimism and Sunnyside Labs to validate OP Stack-based infrastructure for the Korean market.

The three-month proof-of-concept aims to answer whether banks can directly control settlement and clearing on the network, if know-your-customer and anti-money-laundering rules can be enforced at the protocol level, and whether individual transaction data can remain private even when transactions run on a public blockchain.

Toss wants 'Ethereum-level trust and security' while tailoring the system to Korean currency and local services. The company plans to connect this future chain to other networks so assets and payments can move easily across ecosystems.
