• Agglayer v0.3 goes live on mainnet.

• Lodestar architecture built with Zig.

• Federal Reserve ends reputational risk.

• Aave DAO votes on Chainlink SVR Phase 3.

Agglayer, a unified network aggregation layer, deployed its v0.3 upgrade to mainnet. The update enhances pessimistic proofs with a new execution proof mode, enabling chain-agnostic interoperability without requiring chains to alter their existing architecture. The upgrade allows non-CDK-based chains to join the Agglayer by proving their own state using ZK proofs. The v0.3 upgrade also verifies state finality, ensuring a sending chain has finalized its state before interop. Katana, a new DeFi-focused L2, will be the first to launch using the Execution Proof Module, combining the OP Stack with ZK-based security. Polygon PoS will connect to Agglayer by the end of Q3 using a proof-of-consensus.

Lodestar, the Ethereum consensus client maintained by ChainSafe, is transitioning from a browser-focused JavaScript architecture to a high-performance hybrid architecture using Zig and JavaScript, with Bun as its new runtime. Bun, a fast JavaScript runtime written in Zig, will replace Node.js in Lodestar 2.0. Lodestar will retain browser support through TypeScript and WebAssembly. Zig is a low-level programming language known for its performance, predictability, and fine-grained control, enabling better memory management and native performance. The transition enables faster execution and streamlined tooling.

The Federal Reserve Board announced it will no longer include reputational risk as a formal component in its bank examination programs. Instead, supervisory materials will shift focus to more specific, objective financial risks. The change reduces informal barriers for banks considering relationships with crypto firms. It removes a subjective factor that has previously been cited in prior decisions to avoid the crypto sector. The move follows an April decision by U.S. federal banking regulators to rescind earlier guidance requiring pre-approval for bank involvement in crypto-asset and stablecoin activities.

A new AaveDAO governance proposal aiming to activate Chainlink Smart Value Recapture (SVR) feeds for ETH-correlated assets and USDC on the Aave V3 Ethereum Core instance is now open for voting. Chainlink SVR is an advanced oracle system that helps DeFi protocols recapture non-toxic Maximal Extractable Value (MEV) from liquidations using Chainlink Price Feeds. This proposal represents Phase 3 of the SVR rollout on Aave, building on two earlier phases that successfully integrated SVR for BTC-related and select ETH-related assets. The system has generated $51,000 in revenue for the Aave DAO through 51 SVR-driven liquidations.
