**OP Mainnet now processes 29% of all crypto card transactions**, with ether.fi Cash accounting for the majority of this volume. The platform migrated to OP Mainnet in April, citing infrastructure advantages: - **$0.00001 median transaction fees** - **Sub-250ms finality** with Flashblocks - **99.99% uptime** year to date - **20M gas/second** maximum throughput The move reflects a broader trend of applications choosing OP Mainnet for cost-effective, high-performance operations. MetaMask Agent Wallet also recently launched with OP Mainnet support, enabling AI agents to execute multiple transactions without significant cost overhead.

Ink is rolling out chain and asset-level upgrades designed to support round-the-clock onchain capital markets. The improvements focus on two key areas: - **Security enhancements** to protect market infrastructure - **Compliance features** to meet regulatory requirements The team plans to share additional technical details and implementation timelines in the coming weeks. These upgrades build on Ink's existing infrastructure partnerships aimed at bringing institutional-grade financial products to both retail and professional users.

**Celo reached 10 million unique addresses** five months after transitioning to an Ethereum Layer 2 in March 2025. The network maintains **469,000 daily active addresses**, with activity concentrated in: - Stablecoin transfers - Tokenized gold transactions - Currency swaps This milestone demonstrates sustained adoption following Celo's strategic move to become an Ethereum L2, positioning it among the more active Layer 2 networks in the ecosystem.

**World Chain** is launching a technical first for Layer 2 networks. The network will stream **EIP-7928 block access lists** inside every flashblock - a feature currently live on Sepolia testnet and scheduled for mainnet deployment on **August 17**. This makes World Chain the first production L2 to implement this streaming capability. **What this means:** - Block access lists help optimize transaction execution - Streaming them in real-time within flashblocks could improve network efficiency - Part of the broader OP Stack ecosystem's technical evolution The deployment follows the Superchain's recent Isthmus hardfork, which brought Pectra upgrades to multiple OP Stack chains including Base, OP Mainnet, and Unichain.

Lee Ju-sik highlighted **Optimism's unique flexibility** in navigating South Korea's regulatory landscape. The Layer 2 solution enables institutions to build customized compliance frameworks that adapt to different jurisdictions. This approach addresses the challenge that regulatory requirements vary significantly across borders. **Key advantage**: Optimism allows organizations to construct precisely what they need to meet local regulatory standards, regardless of where they operate. This flexibility positions Optimism as a practical solution for institutions seeking to expand blockchain operations while maintaining compliance in multiple markets.

**DB Securities partners with Optimism to navigate Korea's regulatory landscape** DB Securities is leveraging the OP Stack to connect public and private blockchain infrastructure while complying with South Korea's distributed ledger requirements for tokenized securities. **Key developments:** - Korea's tokenized securities market operates on permissioned distributed ledgers, making public network partnerships rare - DB Securities is bringing underlying assets onchain through its Optimism partnership - This approach differs from the typical closed-system model in Korean finance **Broader context:** OP Enterprise has secured partnerships with major Korean financial players including Dunamu (Upbit operator), Toss, and DB Securities - all adopting OP Stack infrastructure within three months. The move demonstrates how traditional financial institutions can bridge regulatory compliance with public blockchain technology.

European crypto exchange **Bitpanda** is launching **Vision Chain**, a programmable financial infrastructure built on the OP Stack through OP Enterprise. The platform aims to enable continuous financial operations beyond traditional market hours. **Key features:** - Serves 7M users across Europe - 200ms block times for fast transactions - OP Succinct ZK proofs enabling same-day L1 withdrawals - First fully managed OP Enterprise partnership - Purpose-built for institutional finance As a regulated European exchange, Bitpanda is positioning Vision Chain as infrastructure for institutional-grade financial services that operate around the clock, removing the constraints of traditional market operating hours.

**Toss, South Korea's dominant payment platform serving two-thirds of the country's population, is exploring putting the won onchain.** The financial technology company is investigating blockchain integration for the Korean currency. This move could represent a significant step toward mainstream adoption of onchain finance in one of Asia's most technologically advanced markets. Toss's exploration comes as the company continues to dominate South Korea's digital payment landscape. The platform's massive user base positions it as a potential bridge between traditional finance and blockchain technology. Details about the implementation timeline and technical approach are outlined in [Optimism's blog post](http://optimism.io/blog/two-thirds-of-south-korea-runs-its-money-through-toss-now-toss-is-exploring-putting-the-won-onchain).

**South Korea's largest fintech app Toss is exploring an onchain Won stablecoin in partnership with Optimism.** Toss serves over 30 million users—two-thirds of South Korea's population—who manage banking, payments, investing, credit, and taxes through the platform. **Key implications:** - Korea has 16 million active crypto traders, creating significant existing demand - A Toss-sized stablecoin would become one of the largest regulated onchain money experiments globally - The stablecoin would operate within an app most Koreans already use daily The memorandum of understanding (MOU) between Toss and Optimism marks a potential shift toward mainstream blockchain adoption in one of crypto's most active markets.

A proof-of-concept test is underway for a Korean Won-backed stablecoin that combines regulatory compliance with blockchain privacy. **Key Components Being Tested:** - OP Enterprise for settlement control - KYC and AML systems built to Korean regulatory standards - Sunnyside Labs' @PrivacyBoost for private transactions on public networks The test, involving Optimism, @PrivacyBoost, and @toss__official, runs over three months to determine if digital money can settle onchain while meeting Korea's requirements for compliance, privacy, and institutional control.
