Toss Partners Optimism and Sunnyside Labs to Validate Won Stablecoin Infrastructure on July 8

According to Viva Republica, Toss has signed a memorandum of understanding with Ethereum Layer 2 project Optimism and privacy technology firm Sunnyside Labs on July 8 to validate digital financial infrastructure for developing a won-linked stablecoin.

The three parties will conduct a proof of concept over the next three months to test whether Optimism's OP Stack blockchain framework can be applied to South Korea's financial infrastructure. The PoC will focus on validating institutional payment and settlement controls, KYC and AML compliance, and transaction privacy protection in public blockchain environments. Optimism will provide blockchain infrastructure while Sunnyside Labs will contribute Privacy Boost technology, designed to protect sensitive transaction data while enabling authorized financial institutions to access required information.
