superchain

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.

According to official news, Optimism has released the quantum-resistant roadmap for Superchain, with the core content announcing the gradual phasing out of externally owned accounts (EOA) based on ECDSA signatures over the next decade. The specific plan is that by January 2036, EOA transactions using ECDSA signatures on the OP mainnet and superchain will be deprecated, and all such accounts must delegate their key management to smart contract accounts that support post-quantum signatures.The roadmap covers both user and consensus levels. At the user level, account abstraction technology will be utilized, through standards like EIP - 7702, to gradually delegate signature authority from EOA to smart accounts capable of verifying post-quantum signatures. At the consensus level, L2 sequencers and batch submitters will migrate to post-quantum signatures, while also calling for Ethereum itself to establish a timeline to transition validators from BLS signatures and KZG commitments to post-quantum algorithms. The entire upgrade process will be coordinated through a hard fork, providing the ecosystem with a decade to achieve a smooth transition.

Ethereum L2 network Optimism stated that DAOs are facing challenges in fund allocation. The Optimism Foundation has proposed a plan aimed at more closely linking OP tokens with the success of Superchain.According to the proposal, starting from February of this year, 50% of Superchain's revenue will be used to buy back OP tokens. In addition, the Optimism Foundation will adjust its capital allocation methods to invest more effectively in the Superchain, enhancing the role of OP tokens within the Superchain.

Deposits and on-chain activities will continue as normal, and this invalidation will not pose any risk to any ETH or ERC-20 tokens.The official reminder for users is to ensure that all pending withdrawals are completed before 17:00 UTC on October 7, 2025. Any incomplete withdrawals will need to be re-validated after the upgrade is completed.

ChainCatcher message, Optimism stated on platform X that the Superchain 16a upgrade proposal will soon be submitted for execution after governance approval: it will be deployed to Superchain Sepolia on September 22 and to the Superchain mainnet on October 2. This is a maintenance upgrade that will replace U16 in a more secure and flexible manner.

ChainCatcher news, according to official sources, OP Labs will test the improved Superchain event response feature today at 14:30 (UTC). As a result, the mainnet withdrawals of the Superchain network will be paused for about 20 minutes. However, this will not affect any L1 to L2 deposit transactions or L2 transactions. Users or operators do not need to take any action.

ChainCatcher news, the Optimism core development team OP Labs has successfully activated the Isthmus hard fork, introducing key features of the Ethereum Pectra upgrade into the OP Stack and Superchain ecosystem, becoming the first L2 ecosystem to support Pectra.This upgrade covers multiple OP Stack chains including Base, Ink, OP Mainnet, Soneium, and Unichain.

ChainCatcher news, according to Cointelegraph, the blockchain infrastructure protocols Celo, Chainlink, Hyperlane, and Velodrome have launched a cross-chain version of USDT called "Super USDT" on the OP Superchain.This stablecoin will be fully backed by an equivalent USDT reserve locked in the Ethereum scaling solution Celo, enabling its cross-chain functionality through Chainlink's cross-chain interoperability protocol and another open interoperability framework, Hyperlane.

ChainCatcher news, Sony's Layer2 project Soneium officially announced on social media that 100 million ASTR will soon be distributed through community incentives.The Astar Contribution Score (ACS) campaign will be launched on Soneium, aimed at promoting on-chain adoption, expanding the role of ASTR in the Superchain, and rewarding ecosystem participation.By interacting with dApps, participating in Web3 experiences, and contributing to network activities, users will earn ACS points, which can be redeemed for ASTR at the end of the campaign.

ChainCatcher news, Ethereum L2 solution Optimism disclosed in a post on X that the revenue contributed by the OP Chain in Superchain has exceeded 14,000 ETH.It is reported that each OP chain in Superchain operates under a standardized revenue-sharing model, where each chain returns a portion of its revenue to the Optimism Collective through a fee-sharing mechanism followed by the network. The fee-sharing is calculated as the greater of 2.5% of the chain's revenue or 15% of the chain's profit, defined as fee revenue minus L1 gas fees.
