Lighter officially stated on X that it has completed the escape mechanism verification conducted by the third party L2BEAT, which means that even if the sequencer at the L2 level fails, users can withdraw funds from Lighter's L2 back to Ethereum in a permissionless manner. It is the first L2 Perp DEX in the industry to achieve this functionality.

Anatoly Yakovenko (toly), co-founder of Solana Labs, responded to discussions about the decentralization level of Hyperliquid, stating that he has raised the same criticism for all L2s: the key to determining whether a system is permissionless lies in whether users can participate in any part of the protocol stack using their own resources without approval from a trusted third party.If they cannot, it is not permissionless. Toly stated that no matter what users do, they cannot run the Base sequencer or the Hyperliquid sequencer, so this is the same issue he criticized with L2s.

The Optimism governance layer has passed a proposal to more closely tie the OP token to the economic performance of Superchain. This marks a significant shift in how token value and revenue usage are approached in one of Ethereum's largest Layer 2 ecosystems.According to the proposal, the Optimism Foundation will use 50% of the net revenue from the Superchain sequencer for regular buybacks of OP tokens during a 12-month pilot period starting in February. The remaining revenue will continue to support the ecosystem fund, finance projects, and operations.According to data from the Optimism on-chain governance portal, the proposal was approved with an 84.4% support rate after several days of discussion among representatives and token holders.This initiative is Optimism's first formal attempt to link the demand for OP tokens with the activities of the Superchain full network. Superchain is an ever-expanding collection of chains built on the OP Stack, including the OP mainnet, Base, Unichain, World Chain, Soneium, Ink, and more.

ChainCatcher message, Base announced on social media early yesterday morning that it experienced a network interruption lasting 33 minutes, which caused a pause in block production.Base stated that the interruption was due to an automatic switch to a mainnet sequencer in an abnormal operating state within the high availability cluster. The Base team acted quickly, switching to a healthy mainnet sequencer, after which the Base chain resumed normal operations. The team has now completed a comprehensive post-incident analysis and will share the details of the event, the solutions, and specific measures to prevent similar incidents in the future.

ChainCatcher news, Paradigm researcher Dan Robinson stated on social media that whether a sequencer is decentralized is not the most important factor; the key lies in the rules it follows and whether it will use its power to harm user interests or engage in value extraction. He pointed out that decentralized sequencers can also be extractive, while centralized sequencers can be non-extractive.For layer two networks, long-term censorship resistance and activity mainly come from layer one networks. The attributes of the sequencer (including censorship resistance, transaction pool privacy, and sorting rules) are the most important considerations; "decentralization" itself cannot fully define the nature of a sequencer.

ChainCatcher news, according to official sources, the shared sorter solution Radius has announced the completion of a $7 million seed round financing, led by Pantera Capital.According to the introduction, Radius is a trustless sorting layer that provides sorting as a service and cross-rollup interoperability solutions for dedicated blockchains known as rollups. In 2025, Radius will launch Lighthouse to help Rollups capture MEV revenue, and by 2026, Radius plans to expand on Ethereum to increase revenue opportunities.

ChainCatcher news, Layer 2 scaling solution Metis officially announced the latest progress on Twitter. It is reported that currently, 414,193 METIS tokens have been locked for sequencer mining.Metis stated that over the past 6 months, more than 6% of METIS tokens have been removed from circulation supply to protect network security.

ChainCatcher news, according to CoinDesk, the shared sequencer network Astria announced the completion of a $12.5 million funding round, led by dba and Placeholder VC, with participation from RockawayX, Maven11, 1kx, Bankless Ventures, Figment Capital, and Batu, as well as angel investors such as Yuki, DCBuilder, Hasu, Will Price, and Jason Yanowitz. The new funds will be used to continue building the Astria sequencer layer and Astria Stack.

ChainCatcher message, the Metis ecological LSD protocol ENKI indicates that the first phase of sorter node rewards will be distributed within three days, and all users who stake eMETIS through seMETIS will receive rewards.

ChainCatcher news, the Ethereum L2 project Metis announces that the second phase of the decentralized sequencer is about to launch, which will implement sequencer mining. Users will be able to lock METIS through Artemis and ENKI to earn a share of the network revenue and receive METIS LST that can be further used within Metis.

ChainCatcher news, Metis announced that it will activate a hard fork at block 16,500,000 in about 7 days to complete the second phase of the decentralized sequencer upgrade. Metis previously achieved the addition of multiple nodes to the sequencer pool and introduced sequencer rotation in the first phase, significantly enhancing the network's censorship resistance and vitality.It is reported that the second phase of this upgrade will introduce features such as multiple transactions within a single block, transaction pools, and sequencer rewards, making Metis the first Ethereum Layer 2 scaling solution to achieve sequencer decentralization.

ChainCatcher news, the Ethereum Layer2 network Metis has launched the alpha version of the decentralized sequencer, where sequencer nodes will receive METIS rewards to incentivize their participation in block generation and transaction processing. In the first year, all sequencer nodes will have a 20% mining reward rate.In response, the Metis development team stated that this will be the first Ethereum Rollup to support decentralized sequencers.
