Optimism

Optimism has released the **Actions SDK Developer Preview**, an open-source TypeScript toolkit designed to streamline onchain operations. **Key Features:** - Embed wallets and DeFi functionality without complex infrastructure - Perform lending, borrowing, swapping, and payments with minimal code - Reduces development from weeks to hours and 2000+ lines to just 20 lines - Single dependency architecture The SDK aims to help developers bring fintech applications onchain more efficiently. Interested developers can learn more at [optimism.io/learn-more](https://www.optimism.io/learn-more?utm_source=twitter&utm_medium=twitter&utm_id=actions&variant=actions) or explore documentation at [actions.optimism.io](https://actions.optimism.io/).

A new yield automation system is being built using two major DeFi protocols as action providers. **Key Features:** - **[Aave](https://aave.com)** integration brings $30B+ TVL and institutional-grade infrastructure - **[Morpho](https://morpho.org)** provides optimized yield aggregation - Single configuration file manages protocols, markets, and assets - Users deposit USDC and earn yield automatically The system simplifies DeFi yield farming by handling protocol interactions behind the scenes. Additional features are planned for future releases.

Actions SDK now supports three embedded wallet solutions: Privy, Turnkey, and Dynamic. After evaluating over 100 wallet providers, these integrations enable seamless onchain experiences where users remain unaware of blockchain interactions. **Key features:** - Embedded wallet support from three leading providers - Invisible blockchain operations for end users - Simplified onchain adoption This follows previous implementations like DIMO's use of Turnkey for global account management, demonstrating the growing importance of embedded wallets in web3 user experience.

A new product called **Actions** aims to solve a critical gap for financial product builders: users expect 5-10% yields, but traditional offerings provide only 0.1%. **The Problem:** - DeFi protocols can deliver higher yields - Integration requires weeks of specialized development work - Most teams lack the expertise or resources **The Solution:** Actions serves as an entry point, simplifying DeFi integration for traditional financial products. This builds on a broader trend toward **AI-powered yield management** that: - Monitors 100+ platforms in real-time - Auto-diversifies across stablecoins (USDT, USDC, DAI) - Provides risk-based yield suggestions - Distinguishes real yield from subsidy-driven returns The vision: transform DeFi from a manual, complex process into AI-managed digital savings accessible to mainstream users.

Optimism has shared updated network statistics and data visualization. **Key Information:** - Current network metrics and performance data are now accessible - Statistics dashboard provides real-time insights into the Optimism network - Data includes transaction volumes, network activity, and other key performance indicators For detailed metrics and charts, visit the [Optimism stats dashboard](http://stats.optimism.io).

Optimism has opened its platform for developers to launch custom blockchains built on its infrastructure. The initiative allows teams to create their own blockchain networks while leveraging Optimism's scaling technology. Developers can access the build tools through [Optimism's website](https://www.optimism.io/build) and [developer console](https://console.optimism.io/build). **Key features:** - Launch custom blockchain networks - Built on Optimism's proven infrastructure - Access to Ethereum's security and ecosystem This move expands Optimism's superchain vision, enabling more projects to deploy independent chains while maintaining interoperability with the broader Ethereum network.

**Optimism's Superchain is becoming the dominant Layer 2 infrastructure for Ethereum**, now processing 58.5% of all L2 transactions across its network of chains. **Major platforms building on the Superchain include:** - Base - World Chain - Celo - OP Mainnet - Unichain **Real-world adoption is accelerating.** Celo's MiniPay is facilitating global payments, while Worldcoin's World App has become the #1 wallet globally by monthly active users (according to Sensor Tower). The Superchain addresses Ethereum's throughput limitations by offering: - Higher transaction capacity - Customizable execution environments - Improved user experience - Ethereum-grade security All networks in the ecosystem share security infrastructure, upgrades, and services maintained by Optimism, creating a unified scaling solution for Ethereum as institutions and consumers move onchain.

The OP Stack rollup ecosystem is being challenged to pass the "walkaway test" - a critical benchmark for decentralization where a protocol can continue operating even if its original developers completely disappear. This test represents a key milestone for Layer 2 solutions built on the OP Stack framework. Passing it would demonstrate true decentralization and resilience, removing single points of failure and dependency on core teams. The challenge highlights the ongoing evolution of Ethereum scaling solutions toward greater autonomy and trustlessness.

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.
