ChainCatcher message, encrypted consumer application Abstract announced that its testnet is now live, supported by ZK Stack, operating as L2 on the Ethereum Sepolia testnet. Developers can use this testnet to test applications, ensuring smooth operation before the Abstract mainnet launch later this year.

ChainCatcher message, the security agency OpenZeppelin has completed an audit of the state transition contracts in the zkSync ZK Stack codebase. This audit identified 19 issues, including 2 medium severity issues, 6 low severity issues, and 11 comments and additional information. Currently, out of the 19 issues, 18 have been resolved, and 1 has been partially resolved.

ChainCatcher news, Omar, the head of BD at zkSync developer Matter Labs, proposed in the TreasureDAO community that Treasure Chain use ZK Stack as Layer2, which will enable TreasureDAO to vertically scale through game or application-specific Layer3 chains. In addition, Matter Labs stated that they are working with the Lambda Class team to allow ZK Stack chains to have their own native Gas token, and Treasure Chain can use MAGIC or any other ERC-20 as the Gas token.

ChainCatcher message, the hybrid on-chain exchange GRVT posted on X that it is building an application chain based on ZK Stack. ZK Stack is a modular framework that builds custom ZK-supported superchains based on the open-source code of zkSync Era.

ChainCatcher news, the startup venture studio LambdaClass announced a new strategic partnership with zkSync, aimed at contributing to the entire ecosystem, with a focus on verticals such as enhancing the ZK Stack and introducing applications to zkSync.In the past few days, some of LambdaClass's top engineers have joined the zkSync team.

ChainCatcher news, Matter Labs co-founder and CEO Alex stated in the latest community AMA that zkSync is now fully focused on Era, aiming to build a scalable value internet using the ZK Stack.zkSync Era will switch to the STARK-based proof system Boojum, which is currently in the final stages. Once the switch is complete, it will bring more efficient oracles and lower-cost on-chain privacy.

ChainCatcher news, Opside officials stated that they will strongly support the promotion of zkEVM, including the recently announced ZK Stack from zkSync. Currently, the Opside testnet has integrated Polygon zkEVM (Hermez), allowing users to issue their own zkEVM chain on L1 public chains such as ETH, BSC, and Polygon with one click.According to the roadmap, the Opside testnet is expected to integrate zkSync's ZK Stack in August. In the future, zkEVM solutions such as Scroll and Linea will also be provided. Opside's multi-chain ZK-PoW algorithm will provide massive computational power support for ZK-Rollups on various public chains.

ChainCatcher news, zkSync announced the launch of a modular open-source framework called ZK Stack for building custom zkRollups. ZK Stack will empower developers with complete autonomy, from choosing data availability models to using their own tokens for decentralized ordering.It is reported that ZK Stack offers two key features: sovereignty and seamless connectivity. Creators have full rights to the code and enjoy unrestricted autonomy to customize and shape various aspects of the zkRollup chain. These zkRollup chains operate independently, relying solely on Ethereum L1 for their activity and security, while cross-chain bridges exist to facilitate interconnection between each chain, achieving trustless, fast (within minutes), and low-cost (per transaction) interoperability.
