ZKsync introduced Elastic Chains, a network of interoperable ZK rollups similar to Polygon’s Agglayer. Elastic Chains will include custom instances of ZK rollups, validiums, or volitions, all built on the ZK Stack. The chains will be interoperable amongst chains on the network, providing access to secure bridging, low fees, and unified liquidity. The Elastic Chain architecture features a ZK Router on Ethereum that manages state and shared liquidity and a ZK Gateway middleware that facilitates interactions with Ethereum. The framework aims to offer limitless chain expansion and seamless interoperability, secured by mathematical proofs. ZKsync anticipates over 20 ZK Stack chains to go live by the end of the year.

Balancer released its codebase for Balancer V3, the latest protocol iteration designed to simplify custom pool development. Balancer V3 introduces several innovations, including a transient accounting system via EIP-1153, re-entrant pool lifecycle hooks, native yield-bearing token support, fully boosted pools, and a flexible router design. Balancer V3 shifts core functions such as token management, fees, rate scaling, and liquidity operations, from the pool contracts into a unified vault contract. The unification ensures that all pools adhere to the same standards, maintaining consistent pool states across the protocol. Balancer is open to feedback for its V3 codebase, which is open-source under the GPL 3 license.

Blockchain infrastructure provider RISC Zero introduced Blobstream Zero, a zkVM-based Blobstream bridge designed to connect Celestia’s data availability layer with various blockchain ecosystems. Blobstream is Celestia’s solution for enabling rollups to utilize Celestia light clients for Data Availability Sampling. Blobstream Zero introduces the ability to verify Celestia DA using zero-knowledge proofs. The integration allows rollups and applications to generate proofs across chains more efficiently. Blobstream Zero also introduces ZK Coprocessors, enabling dapps on Ethereum, Optimism, and Solana to run data-intensive ZK programs without sacrificing composability.

Aave's GHO stablecoin is now natively available on Arbitrum One. The deployment uses Chainlink Cross-Chain Interoperability Protocol (CCIP), which uses a lock/burn and release/mint bridge mechanism. The launch is part of GHO’s cross-chain strategy aiming to make the stablecoin more accessible. The Aave DAO has allocated 750,000 ARB tokens from the Arbitrum Long-Term Incentives Pilot Program (LIPP) to incentivize GHO liquidity on Arbitrum.
