The engine allows users to specify their desired intent while a network of solvers compete for optimal execution based on cost and speed. The Universal Intent Engine is built on four core components: the Message Standard, the Broadcast Standard, Fast Settlement, and the Intent Dissemination Feed, a universal feed where users, solvers, and applications can interact and execute cross-chain intents. The Universal Intent Engine is set to launch by Q1 2025, with native crosschain operations rolling out in Q3 2025. SOCKET Integrates Agglayer Infrastructure ----------------------------------------- SOCKET is [leveraging](https://mirror.xyz/socket.eth/SdriZm8Nhq_IHvbRP9XLROicewERYBuzjv80BJvTasM?referrerAddress=0x7CdA10f1C4e11d9C536009e43F141743D11F2FED) Polygon’s Agglayer to enable developers to build applications across chains without cross-chain messaging or bridging. The integration allows developers to compose Solidity contracts and deploy them on their own app gateway, which interacts with SOCKET to facilitate seamless cross-chain functions. Users interact with apps via the app gateway by simply sending signed messages that are processed in the gateway and then executed onchain, leveraging pessimistic proofs via the Agglayer. SOCKET is a chain abstraction protocol that enables a single unified balance and instant transactions, with no bridging required. Ethereum Protocol Studies Program --------------------------------- The Ethereum Foundation [announced](https://blog.ethereum.org/2025/02/05/ethereum-protocol-studies) the return of Ethereum Protocol Studies (EPS), a structured learning program designed to make Ethereum’s core protocol more accessible. This year’s program will focus on Ethereum’s Execution and Consensus Layers, client architecture, and key research areas, providing participants with a deeper understanding of the network’s inner workings. Over the past year, EPS has expanded [epf.wiki](http://epf.wiki), a collaborative knowledge base on the Ethereum protocol. The 2025 program includes two onboarding weeks, six weeks of deep dives into Execution and Consensus Layers, live seminars with engineers and researchers, and a dedicated Discord server. A town hall Q&A will be held on February 12, 2025, at 15:00 UTC.

Under acting FDIC Chair Travis Hill, the agency is exploring ways to make it easier for banks to safely offer custody services for crypto assets. According to a person familiar with the matter, some banks have already met with FDIC officials to discuss offerings.
