**Optimism partners with Toss to explore blockchain-based finance in South Korea** Toss, the financial super-app used by over 30 million South Koreans (two-thirds of the population), has signed an MOU with Optimism to test putting the Korean Won onchain. **Key details:** - Three-month proof of concept launching with Optimism, PrivacyBoost, and Toss - Testing a Won-backed stablecoin built on the OP Stack - Focus on meeting Korea's compliance, privacy, and control requirements - Toss handles banking, payments, investing, credit, and taxes for users The pilot will determine whether money can settle onchain while maintaining regulatory standards. If successful, this could establish the OP Stack as infrastructure for compliant digital finance at national scale.

**Four major regulated financial institutions have adopted the OP Stack across different markets within a year:** - **Europe**: Bitpanda's Vision Chain serves 7M users with 200ms blocks and OP Succinct ZK proofs for same-day L1 withdrawals - **US**: Kraken's Ink on OP Enterprise - **Japan**: Mitsui's Zipangcoin - **Korea**: Toss Bitpanda represents the first fully managed OP Enterprise partnership, building purpose-built infrastructure for institutional finance as a regulated European exchange.

OP Mainnet has become the infrastructure backbone for ether.fi's neobank card program, meeting three critical requirements: - **Real-time authorization** for card swipes - **Low transaction fees** that preserve yield economics - **Stability during payment spikes** The platform currently supports ether.fi's operations with $220M in total value locked, 70,000 active cards, and 300,000 accounts. Transaction costs remain at fractions of a cent, enabling the business model to scale profitably. Daily spending continues to reach new highs following the migration to OP Mainnet.

Optimism has introduced **OP Enterprise**, a managed blockchain infrastructure service designed specifically for businesses. The core premise is simple: different businesses require infrastructure tailored to their specific needs rather than one-size-fits-all solutions. **Key features include:** - Production-grade managed infrastructure - Businesses retain ownership of their blockchain - Companies keep their revenue - Enterprise-level guarantees Karl Floersch and Ben Jones discussed the rationale behind OP Enterprise on the Blockworks Empire podcast with Jason Yanowitz. The service addresses a critical issue: enterprises currently build on platforms that capture the value they create, rather than allowing businesses to retain that value themselves. OP Enterprise represents Optimism's move into providing dedicated blockchain solutions for corporate clients who need reliable, scalable infrastructure without sacrificing control or revenue.

Optimism has launched **OP Enterprise**, a new blockchain solution designed specifically for business applications. The platform aims to provide organizations with: - Fast transaction processing - Stable performance - Scalable infrastructure built on Ethereum This initiative represents Optimism's push to bring enterprise-grade blockchain capabilities to businesses looking to leverage Ethereum's ecosystem while meeting corporate requirements for reliability and performance.

**OP Labs has introduced OP Enterprise**, a managed infrastructure service that allows organizations to deploy and operate OP Stack chains without handling the technical operations themselves. **What it includes:** - Managed deployment and operations of OP Stack chains - Pre-integrated infrastructure: RPCs, oracles, bridges, indexers, wallets - Compliance, custody, and stablecoin support built-in - Direct support from OP Labs instead of third-party providers **The shift:** OP Labs is moving away from legacy support through rollup-as-a-service providers to offer direct production support. Teams can now work directly with the builders of the OP Stack through a single relationship. **Why it matters:** Launching a production blockchain typically requires integrating multiple services, which adds significant time and complexity. OP Enterprise consolidates these requirements so development teams can focus on building products rather than managing infrastructure.

Centralized exchanges (CEXs) have quietly become significant distributors of onchain activity, according to a new analysis from Optimism. The shift represents a notable evolution in the crypto ecosystem. While decentralized exchanges (DEXs) were designed to eliminate intermediaries, CEXs have adapted by facilitating onchain transactions at scale. **Key developments:** - CEXs now process substantial volumes of onchain transfers and settlements - Traditional exchanges are bridging users to Layer 2 networks and DeFi protocols - The trend challenges assumptions about the CEX vs DEX divide This development suggests the future may involve coexistence rather than competition between centralized and decentralized platforms. CEXs bring regulatory compliance and user familiarity, while enabling access to onchain infrastructure.

**Regulatory clarity is accelerating enterprise blockchain adoption in Japan.** Kyle Jenke discusses Mitsui's deployment on OP Mainnet, highlighting how supportive regulatory frameworks are making Japan a key market for institutional crypto adoption. **Key developments:** - Mitsui, a major Japanese conglomerate, has deployed on OP Mainnet - Japan's clear regulatory approach is encouraging enterprise movement into blockchain - The country's crypto accounts surpassed 11 million, demonstrating rapid adoption - Japan's pioneering regulatory framework is fostering safe and sustainable crypto growth The conversation with Genzio Co. emphasizes that when regulators actively encourage adoption rather than create barriers, enterprises respond with concrete deployments and infrastructure investments.

The OP Stack is enabling a new era of blockchain customization, according to insights from @karl_dot_tech. **Key Points:** - Customization allows blockchains to be tailored for specific use cases and requirements - The OP Stack provides the infrastructure to make this customization technically feasible - This represents the next significant wave of innovation in crypto development The ability to customize blockchains opens new possibilities for developers to create specialized solutions rather than one-size-fits-all networks.

The **Scaling Summit** brought together founders and builders to address critical industry challenges: - **User retention** in an attention-scarce market - **Product differentiation** in a crowded builder landscape - **Compliance frameworks** that balance regulation with innovation momentum - **RWA and stablecoin adoption** beyond builder narratives toward mainstream use The event focused on practical solutions rather than theoretical discussions, with participants examining how to move from concept to global implementation.
