ChainCatcher news, Cronos Labs announced that the Cronos zkEVM mainnet is officially live.Cronos zkEVM is a Layer-2 blockchain built on Ethereum, powered by ZKsync technology. Its testnet was launched in December 2023, processing millions of transactions and having over 3 million unique addresses.Cronos zkEVM uses zkCRO (a liquid staking version of $CRO) as the gas token.

ChainCatcher news, Astar Network announced on social media that the Astar zkEVM mainnet will undergo maintenance from June 27th, 21:00 to 23:00. During this period, the Astar zkEVM mainnet will be unavailable.The team is conducting this maintenance to migrate the network to new infrastructure and ensure a successful migration. Last week, the same migration for the Astar zkEVM testnet (zKyoto) was successfully completed. Once the maintenance is finished, the zkEVM mainnet will be promptly back online.

ChainCatcher message, Polygon announced on platform X that the Polygon zkEVM mainnet testnet has resumed operation. The core team of Polygon zkEVM has made the necessary fixes to the system, thereby restoring L1 settlement for the Polygon zkEVM mainnet Beta. After this upgrade, the emergency status has been lifted, which means that any further updates to the system will require a 10-day time lock to take effect.

ChainCatcher message, Polygon posted on social media that the Beta version of the Polygon zkEVM mainnet is experiencing sorter issues due to L1 reorganization. The team is currently working to resolve this issue and will subsequently release a detailed post-mortem report. This only affects Polygon zkEVM and does not impact Polygon PoS, Polygon CDK, or any chains deployed using Polygon CDK.The second generation zkEVM will be released in the coming weeks.

ChainCatcher news, according to The Block, the Immutable zkEVM mainnet launched in collaboration with Polygon by the Web3 game developer platform Immutable is now available for selected game studios and ecosystem partners, and will be open to the public in the coming weeks.According to the statement, Immutable's current products will also be compatible with Immutable zkEVM, and the chain will provide gasless functionality for gamers using its Immutable Passport non-custodial wallet.

ChainCatcher news, Astar Network founder Sota Watanabe posted on the X platform that Astar's zkEVM mainnet is scheduled to launch in early 2024.

ChainCatcher news, Ethereum's native zkEVM Layer 2 solution Scroll officially posted on the X platform in Esperanto "La estonteco estas malfermita" (The future is open), hinting that its zkEVM mainnet is about to launch.Previous report, in September, Scroll co-founder Ye Zhang stated in an interview at Token2049 that the new zkEVM is expected to launch in a few weeks, and the mainnet has undergone extensive testing and the code has been audited.

ChainCatcher news, Immutable has released the mainnet launch roadmap, which plans to rebuild the Immutable zkEVM testnet in November, upgrading its first EVM client from Polygon Edge to Geth, ensuring that Immutable zkEVM is as close to Ethereum as possible while being fully compatible with the entire Ethereum tool ecosystem; the zkEVM mainnet will go live from December to January next year, with grouped invitations for developers to join before it opens to the public; in 2024, Immutable will provide a dedicated application chain with the same tech stack and features as Immutable zkEVM, but with a unique level of customization; finally, zk-prover will be introduced, providing a trustless Ethereum to Immutable zkEVM cross-chain bridge.

ChainCatcher message, Polygon officially announced that on September 20 at 15:30, the Polygon zkEVM mainnet Beta version will undergo the Dragonfruit upgrade, which will take approximately 2 hours.After the implementation of Dragonfruit, the Polygon zkEVM mainnet Beta version will stay in sync with the latest version of Solidity, maintaining the equivalence of Rollup and EVM by incorporating support for the latest EVM opcode PUSH0. The Polygon zkEVM cross-chain bridge will be temporarily unavailable between September 20 at 15:30 and 19:00.PUSH0 is an EVM opcode included in the Shanghai hard fork.

According to ChainCatcher news and the official announcement, the Polygon zkEVM mainnet testnet will undergo the Dragon Fruit upgrade at 15:30 Beijing time on September 20, lasting approximately 2 hours. Polygon stated that once the Dragon Fruit upgrade is completed, the Polygon zkEVM mainnet testnet will stay in sync with the latest version of Solidity, maintaining the equivalence between Rollup and EVM by supporting the latest EVM opcode PUSH0.

ChainCatcher news, Polygon Labs announced that the Polygon zkEVM mainnet Beta version will be updated on June 8 at 10:00 AM Beijing time. The zkEVM developers will begin collaborating with infrastructure partners to update some services of the network. The update requires the sequencer to be launched, which may cause users to encounter issues when submitting transactions. (source link)

ChainCatcher message, the cross-chain interoperability protocol LayerZero officially stated, "The Polygon zkEVM mainnet is now live, and we will continue to seek to bring LayerZero to every chain." (source link)

ChainCatcher message, Polygon stated in the general FAQ document related to zkEVM that the Polygon zkEVM mainnet will not issue a separate token, and ETH will be used to pay for network gas fees. It is expected that in the future, MATIC will be used for staking and governance in Polygon zkEVM. Additionally, since Polygon zkEVM supports account abstraction through ERC-4337, this will allow users to pay fees using any token. (source link)

ChainCatcher news, the Polygon zkEVM mainnet testnet will go live tonight, and the officially issued commemorative NFT "To Ethereum, with Love" is now open for minting. (Source link)

ChainCatcher news, according to The Block, the Beta version of the Polygon zkEVM mainnet will go live tonight, and Ethereum founder Vitalik Buterin will execute the first symbolic transaction at 22:30.Polygon zkEVM provides a scalability solution for Ethereum applications, with ZK-rollups performing off-chain computations on layer two to enable faster and cheaper transactions while still prioritizing Ethereum's security. The network is EVM equivalent, meaning it will support the same code as Ethereum and allow developers to use their existing tools and infrastructure. (source link)

ChainCatcher message, the Aave community's ARFC proposal on "Deploying the MVP version of Aave V3 on the zkEVM mainnet" is now open for voting. zkEVM is an EVM-equivalent zk-rollup L2 developed by the Polygon team, expected to be deployed on March 27. Aave V3 has been successfully deployed on the ZkEVM testnet for about 6 months.It is reported that this ARFC proposal should be viewed as a "temperature check," allowing developers and risk service providers to conduct a more in-depth analysis of the zkEVM network, with voting ending on March 29 at 18:00.
