ChainCatcher news, the Kakarot team of the Ethereum Layer 2 network recently announced that its testnet has successfully migrated to the Starknet Sepolia network. Developers need to redeploy smart contracts on the new testnet Kakarot Starknet Sepolia.Kakarot is a verifiable EVM built on a STARK-friendly ZK-VM based on Starkware, developed by KKRT Labs, aimed at accelerating the application of zero-knowledge proof technology in blockchain infrastructures like Ethereum through the "STARKification" of the EVM.

ChainCatcher news, according to the Base official website, the fault proof is expected to be launched in mid-July on Base Sepolia (testnet). The fault proof is a crucial implementation step in the process of L2 moving towards decentralization.

ChainCatcher message, Scroll announced on social media that its Curie network upgrade is now live on the Sepolia network.It is reported that the improvements introduced by Curie include: a 1.5 times reduction in Gas costs due to DA compression, comprehensive support for the Ethereum EIP-1559 fee mechanism, and the Curie network will subsequently upgrade on the Scroll mainnet.

ChainCatcher message, Scroll posted on X platform that it is currently upgrading the Sepolia testnet, and the testnet may not be available until June 17 at 12:00 UTC. The latest updates will be notified after the upgrade is completed.

ChainCatcher news, the modular execution layer Fuel announced on social media that it has launched the final testnet on the Sepolia network.

ChainCatcher news, the zkEVM network Kakarot built on the Cairo language announced on social media that it has launched the Kakarot Sepolia testnet and has opened the public whitelist testnet phase.It is reported that this is the first testnet phase of Kakarot.

ChainCatcher news, zkSync Developers posted on social media that the zkSync Era Sepolia testnet is expected to fully recover in the next few hours. The v24 mainnet upgrade will be postponed until later next week to give the team more time to assess the stability of the testnet. A precise release date will be provided when the team is confident in its stability.zkSync Developers stated that there were two issues affecting the testnet (which have now been resolved): First, due to instability in the eth_sender service (responsible for submitting transactions to the L1 zkSync smart contract), there were no L1 submission blocks for about 1 day. This was caused by the gas market on Sepolia being very different due to Blob pricing. Second, there were no proofs submitted for more than two days, leading to withdrawal delays. This was caused by logical differences between the VM inside the circuit (used for generating proofs) and the VM outside the circuit (server-side VM that executes immediately when submitting transactions).

ChainCatcher message, zkSync Developers posted on X platform last night stating that the team is investigating a persistent issue on the zkSync Sepolia testnet. During the ongoing investigation, withdrawing Sepolia funds from the zkSync Era Sepolia testnet is unavailable. This investigation (and its results) may affect the mainnet v24 release scheduled for next Monday.At around 3 AM today, zkSync Developers released an update stating that the investigation is still ongoing and will continue until tomorrow, when more updates will be provided.

ChainCatcher message, meson.network posted on platform X that the Sepolia testnet snapshot will be completed today, and the entire testnet to 1% mainnet mapping is scheduled for May 7, 2024, at 14:00.

ChainCatcher news, according to The Block, OP Labs announced that it has launched Fault Proof on the OP Sepolia testnet, stating: "The open-source, fully functional Fault Proof is now live on OP Sepolia. Through permissionless validation, anyone can participate in the system without an allowlist."It is reported that Fault Proof serves as a security mechanism for Ethereum L2 networks, allowing users to challenge potentially fraudulent or incorrect transactions. They are crucial for ensuring that off-chain transaction processing is not manipulated.

ChainCatcher message, Starknet posted on the X platform that the Starknet Goerli testnet will be deprecated on April 11, and users are advised to migrate to Sepolia as soon as possible.

ChainCatcher news, the blockchain platform Lisk announced on social media that the Lisk Sepolia testnet is now live.Previously, on January 24, the blockchain platform Lisk released its 2024 development roadmap, planning to launch the Lisk L2 testnet in the first quarter of 2024, connecting to the Ethereum Sepolia testnet to provide a testing platform for developers.

ChainCatcher message, Mantle Network announced that its Goerli testnet is scheduled for an upgrade on February 28 at 9:00 AM Beijing time. The upgrade is expected to take approximately four hours, during which RPC services, the Goerli Testnet browser, and cross-chain bridges will be temporarily unavailable, and the network will stop generating new blocks. After the successful upgrade of Mantle Network's Goerli testnet, support for the Goerli testnet will be suspended on March 8 at 8:00 AM.It is reported that the Mantle Network v2 Sepolia testnet is now online, and users are advised to migrate to the Sepolia testnet as soon as possible.

ChainCatcher news, according to official sources, the Doubler market liquidity aggregation investment strategy protocol officially launched on Blast Sepolia on February 1, 2024. To celebrate the launch of this special version, the Doubler team has introduced a special incentive event for Blast Sepolia, with a total reward of 1 million DBR.It is reported that Doubler is an open DeFi protocol that provides a solution for aggregating market liquidity based on an on-chain martingale strategy. It has recently completed a seed round of financing led by Youbi Capital, with participation from 12 other institutions.

ChainCatcher news, the Ethereum Dencun upgrade has been launched on the Sepolia testnet. It is reported that Sepolia is the second of the three testnets for the Dencun upgrade.Earlier this month, Dencun was launched on the Goerli testnet, but initially failed to finalize.In addition, Dencun will go live on its final Ethereum testnet, Holesky, on February 7. After that, developers will sign the date for activating Dencun on the main blockchain. The testnet replicates the main blockchain and allows developers to make any changes to the protocol or its decentralized applications in a low-risk environment.

ChainCatcher news, the Ethereum Foundation announced that Sepolia and Holesky will upgrade in the next two weeks. Dencun will be activated on Sepolia at Epoch 132608 (UTC time January 30, 22:51) and on Holesky at Epoch 29696 (UTC time February 7, 11:35). Once the testnets run the upgrade smoothly, Dencun will be deployed to the Ethereum mainnet as scheduled.
