ChainCatcher news, according to The Block, Zerion has launched a testnet for its Layer 2 Rollup project ZERO Network. This testnet is developed using the ZKSync software package ZK Stack and will become part of the ever-expanding ZKSync ecosystem in the future. The ZERO mainnet is planned to be launched later this year.

ChainCatcher news, the liquidity re-staking platform Swell Network has announced the launch of a Layer 2 rollup chain. Swell's rollup will adopt the "restaked rollup" approach, utilizing the Polygon Chain Development Kit (CDK) and supported by AltLayer. The mainnet is scheduled to go live in the second half of this year. The designated Gas token for the network will be rswETH, and the upcoming token from Swell will be used for governance.The network's restaked rollup structure will include an Active Verification Service (AVS), which is a dedicated service built on top of EigenLayer, facilitating decentralized ordering and validation through EigenLayer's re-staking mechanism. Additionally, the network will integrate EigenDA to meet its data availability requirements.

ChainCatcher news, according to The Block, Injective has launched the Layer 2 Rollup solution inEVM on its mainnet, enabling composability across Cosmos and Solana, allowing Ethereum developers to deploy their applications on Injective without changing their code.It is reported that Injective aims to establish an "Electro Chains" network through inEVM, designed to expand its Layer ecosystem and enhance interoperability with other blockchains. Projects launched on Injective's inEVM mainnet include Celestia, Pyth, TimeSwap, and Thetanauts.
