South Korean finance applicationTosshas entered a strategic partnership withOptimismand blockchain privacy technology developerSunnyside Labsto evaluate the potential use of blockchain infrastructure for future won-based digital financial services. The companies will conduct a three-month proof-of-concept (PoC) project focused on assessing whether Optimism’s OP Stack technology can support blockchain-based financial infrastructure designed for the Korean market. Layer 2 (L2) blockchain technology uses the security and settlement capabilities of Ethereum while enabling faster and more cost-efficient transactions. The evaluation will examine whether financial institutions can maintain control over payment and settlement processes, implement regulatory requirements such as know-your-customer (KYC) and anti-money laundering (AML) procedures, and protect sensitive transaction data on a public blockchain network. These criteria were established by Toss to address the compliance and security requirements of institutional financial services. Blockchain Infrastructure Tested for Institutional Financial AppsThe project will combine Optimism’s OP Stack with Sunnyside Labs’ Privacy Boost technology. Optimism will provide the blockchain infrastructure, while Sunnyside Labs will contribute privacy-focused solutions designed to address transparency challenges associated with public blockchains. Blockchain networks typically make transaction histories and account balances publicly visible, creating challenges for financial applications that require stronger confidentiality protections. Privacy Boost is designed to protect sensitive information while allowing authorized institutions to access necessary transaction details. The technology also aims to support large-scale transaction processing, making it suitable for services involving a broad user base. Optimism’s OP Stack enables organizations to develop customized blockchain networks while maintaining Ethereum-based security standards. The technology is already used by various global companies and platforms, including Sony, Uniswap, OKX, and Kraken. Optimism has also expanded adoption among regulated financial companies seeking blockchain solutions that meet institutional requirements. Through the collaboration, Toss aims to explore the development of dedicated digital financial infrastructure that combines blockchain security with regulatory compliance. The company plans to evaluate how blockchain technology can be integrated with its existing payment ecosystem, which includes more than 30 million users and over 500,000 online and offline payment locations. Optimism Chief Business Officer Kyle Jenke said the partnership would focus on demonstrating whether OP Stack can meet Toss’s technical requirements for performance and privacy. Toss Chief Business Officer Gyuha Kim stated that regulatory compliance and data protection are key factors in applying Web3 technologies to institutional finance, with the project aiming to assess the feasibility of a trusted digital financial infrastructure for the Korean market.
