**ether.fi is now live on OP Mainnet**, bringing its liquid staking protocol to Optimism's Layer 2 network. **Key highlights:** - The protocol completed its migration to OP Mainnet - Users can now access ether.fi's services with faster transactions and lower fees - This follows the February announcement of the planned migration The launch enables ether.fi to leverage Optimism's scalability while maintaining Ethereum security. Users can interact with the protocol directly on OP Mainnet. [Read the full announcement](https://www.optimism.io/blog/ether.fi-is-live-on-op-mainnet)

**Ether.fi has successfully migrated to OP Mainnet**, bringing $220M in total value locked (TVL) - the largest single TVL event in OP Mainnet's history. **Key metrics:** - 300,000 user accounts - 70,000 active cards - Migration completed in 3 days with zero downtime - Cards remained operational throughout the entire process **Technical performance:** - Sub-250ms transaction finality - $0.00001 median transaction fees - 99.99% uptime **What's next:** - Gold Vaults launching soon - Euro card expansion planned - Growing liquidity pool benefits all users The migration demonstrates OP Mainnet's capability to support live consumer products at scale. Ether.fi operates the largest non-custodial crypto card by spend volume, and this move positions both platforms for continued growth in practical crypto payments.

Optimism is participating in the first Ethereum Korea conference, focusing on bringing Korean institutions onto Ethereum and the OP Stack. The initiative represents a strategic expansion into the Korean market, leveraging Optimism's Layer 2 scaling solution to attract institutional adoption in the region. **Key Points:** - First-ever Ethereum Korea conference - Focus on institutional onboarding - Utilizes OP Stack technology - Strengthens Ethereum's presence in Korea This move aligns with Optimism's broader mission to scale Ethereum and expand the Superchain ecosystem globally.

MetaMask has implemented ERC-7715 on OP Mainnet, allowing decentralized applications and agents to request wallet execution permissions. **Key Development:** - Builders can now request execution permissions through the ERC-7715 standard - Opens new permission models for both dApps and autonomous agents - Available on OP Mainnet infrastructure This technical update provides developers with standardized methods to handle wallet permissions, potentially streamlining user interactions with decentralized applications and agent-based systems.

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.

The **Superchain ecosystem** now handles **14.1% of all cryptocurrency transactions**, representing nearly **2x growth** in just five months. **Key metrics:** - $17.8B secured across 30+ chains - 24M+ daily transactions - $6.2B in stablecoins onchain Major chains include Base, Celo, OP Mainnet, Unichain, World Chain, and others building on Ethereum's scaling infrastructure. This growth demonstrates the **increasing adoption** of Layer 2 solutions as users seek faster, cheaper transactions while maintaining Ethereum's security.

**Fusaka is now live on Ethereum mainnet**, delivering the infrastructure needed for Layer 2 scaling. The upgrade introduces **PeerDAS**, which allows validators to sample small data chunks instead of downloading full blobs. This reduces storage requirements from 40-100 GB to just sampled shards. **Key improvements:** - More blob capacity for rollups through Blob Parameter-Only forks - Gas limit increase from 45M to 60M - Lower data availability costs for L2s - Reduced fees for end users The upgrade emerged from **cross-ecosystem collaboration** between Ethereum core developers, client teams, Base, Soneium, OP Labs, and Sunnyside. Teams worked together to solve L2 scaling bottlenecks that were causing rising fees. **For builders:** OP Stack chains now have more throughput headroom, lower L1 data costs, and a predictable scaling roadmap. The implementation included extensive testing through devnets that pushed different client combinations under real rollup workloads.

**Scaling isn't just about bigger numbers** - it's about delivering real value to users, according to insights from @karl_dot_tech at the New Horizon event. Key challenges identified: - Compute bottlenecks - Parallelism implementation - Cross-chain liquidity issues **Real progress requires solving these together**, not chasing TPS metrics alone. *"Through interoperability, we grow the pie. You can build something a competitor builds on, and both of you win."* The focus shifts from raw performance claims to **practical solutions** that enhance user experience and enable true blockchain collaboration.

Optimism Collective announces its H2 strategic goal: achieving $100M monthly in cross-chain asset transfers across interoperable Stage 1 chains. The Citizens House introduces three stakeholder groups: - Top 15 chains by revenue - Top 100 apps by gas fees - End-users with verified activity Key registration requirements: - End-users must prove human status via WorldCoin - Limited spots available - Sybil protection through HumanPassport screening This follows Optimism's recent $2M bug bounty extension for Superchain protocol upgrades, which has already paid out $2.6M since 2022.
