Ethereum L2 Rollup Security Roadmap

Vitalik Buterin published a forum post outlining a roadmap to improve the security, finality, and scalability of Ethereum L2 rollups. To meet L2 data availability demands, he proposes continuing blob space increases, targeting 72 blobs by the Fusaka upgrade. For rollups progressing to Stage 2 decentralization, he proposes a pragmatic fast finality approach using a 2-of-3 hybrid proof system involving optimistic, ZK, and TEE-based provers. Finally, he emphasizes the need for standardized proof aggregation layers—shared infrastructure that bundles ZK proofs from various applications into a single submission to Ethereum. Standardized aggregation layers would significantly reduce gas costs and improve scalability across the ecosystem.

Aave Integrates Chainlink SVR

Aave has integrated Chainlink Smart Value Recapture (SVR) into its V3 Ethereum mainnet market. Chainlink SVR is a specialized oracle solution that enables DeFi protocols to reclaim non-toxic Maximal Extractable Value (MEV) generated through Chainlink Price Feeds. The integration allows Aave to recapture liquidation-related MEV that was previously extracted by block builders. Developed in collaboration with BGD Labs, Flashbots, and other Aave DAO contributors, Chainlink SVR leverages Chainlink Price Feeds and Flashbots’ MEV-Share to redirect value back to DeFi protocols. As outlined in a recently approved Aave DAO proposal, SVR-generated revenue will be split: 65% allocated to Aave and 35% to Chainlink for the initial six months. Aave is now the largest protocol on Etheruem by TVL.

FDIC Updates Crypto Activity Guidelines

The FDIC has rescinded its 2022 Notification of Engaging in Crypto-Related Activities guidance (FIL-16-2022), which required FDIC-supervised banks to notify the agency before engaging in crypto-related activities. In its place, the FDIC has issued new guidance (FIL-7-2025) that permits banks to engage in allowable crypto-related activities without needing prior approval. Under the new guidance, banks may now offer services such as crypto-asset custody, stablecoin reserve management, digital asset issuance, and market making or exchange operations. The FDIC stated it will continue working with other regulatory agencies and the President’s Working Group on Digital Assets.
