According to the official Lido blog, Lido DAO has revoked the "official" bridge endpoints for wstETH on nine networks: zkSync Era, Mode, Scroll, Mantle, Swell, Zircuit, Soneium, Polygon PoS, and Lisk, through a Snapshot vote.This move is a resource adjustment at the governance level and does not affect the technical operation of the related bridges and contracts. Users can still hold, transfer, or bridge back wstETH on the aforementioned networks to Ethereum. Lido will stop security monitoring, ecosystem, and market support for these networks, but no migration deadline will be set.

The development company behind zkSync, Matter Labs, announced layoffs on Tuesday and is fully transitioning the entire organization to the institutional-grade on-chain privacy infrastructure platform Prividium. CEO Alex Gluchowski defined this move on X as a skills restructuring rather than a cost-cutting measure, stating that the products built for regulated financial institutions since 2024 have evolved into Prividium, aiming to provide on-chain infrastructure that combines transaction confidentiality with compliance auditing capabilities for regulated entities such as banks and asset management companies.Gluchowski mentioned that this transformation is based on specific product feedback from institutional clients, but did not disclose the number of layoffs. According to CoinGecko data, the market capitalization of the zkSync token is approximately $115 million, having risen 4.3% in the past 24 hours. This transformation reflects a broader trend in the Layer 2 market, as ZK and L2 projects like Hyli and Botanix have shut down, and general-purpose horizontal platforms are facing pressure to find defenses in vertical fields. As of the time of publication, Matter Labs has not made any statements regarding the future of the zkSync network and ZK tokens.

According to official news, Polygon Labs announced that it will take down the Polygon zkEVM Mainnet Beta sequencer on July 1, 2026, and the timeline was first announced in June 2025.The official reminder states that on-chain wallet assets must be bridged to the Ethereum mainnet via ui.agglayer.dev before this date. On-chain wallet balances that are not bridged in time will be automatically migrated to Ethereum L1 and can be claimed through a dedicated interface afterwards.Polygon emphasizes that it does not control any DeFi protocols on zkEVM, and assets locked in DeFi contracts cannot be automatically migrated. Protocol teams and users must proactively withdraw and migrate liquidity before July 1. Assets that are automatically migrated and not claimed by the deadline will be considered abandoned after December 31, 2027.

According to analysis by BlockSec Phalcon (@Phalcon_xyz), the RollupProcessorV3 contract of Aztec Network was attacked, resulting in losses exceeding $2.15 million. The root cause was that numRealTxs was not effectively bound to the transaction set enforced by the ZK proof, leading to discrepancies in the proof verification path and the L1 settlement logic's interpretation of the transaction list.The attacker exploited this vulnerability to move real deposits to slots not processed by the settlement logic, bypassing the decreasePendingDepositBalance() function, creating unsecured private balances out of thin air, and then withdrawing through the normal settlement process, involving a total of seven assets.

According to token unlocking data from the Crypto asset data platform RootData, zkSync (ZK) will unlock approximately 173.14 million tokens at 00:00 Beijing time on June 17, worth about 1.89 million USD.

According to The Block, Aztec Labs has acquired Obsidion, the company behind the open-source privacy identity verification tool ZKPassport. Its co-founders Michael Elliot and Theo Madzou, along with their team, will join Aztec Labs to continue developing ZKPassport and related applications.Aztec Labs is building the Ethereum privacy layer two network Aztec Network, which raised approximately $60 million worth of ETH through the AZTEC token sale last year, and previously secured about $125 million in venture capital.ZKPassport allows users to read passports or government documents via mobile NFC, generating cryptographic signatures locally for verifying age, nationality, and "real identity" without exposing full privacy. It has been used for ticketing at the Devconnect conference and for compliance identity verification in the Aztec community token sale. Aztec stated that it will continue to keep the ZKPassport protocol and iOS application open source.

ZKsync's official announcement stated that following several ZK token governance proposals, the governance service provider ScopeLift has now launched the "ZK Fee Flow System" proposal on the forum. This system is a set of smart contract mechanisms that allow ZKsync Governance to route and allocate protocol revenue and fees through its controllable on-chain mechanisms. ZKsync indicated that the relevant forum post has detailed the contract architecture, operational mechanisms, security measures, and deployment addresses of the system.

On May 10, Vitalik Buterin published a research article advocating that cryptocurrency payments need to shift from pseudonymity to default privacy, proposing the use of zero-knowledge proof (ZK) transactions to replace standard transfers, allowing users to prove payment validity without exposing their full balance or transaction history.Vitalik specifically pointed out that in the era of agents, autonomous AI agents need to pay service fees (such as LLM API fees) without leaving traceable footprints. By using recursive SNARKs and ZK APIs for points, Ethereum Layer 2 can handle privacy payments at the same speed and cost as transparent transactions. The proposal also includes selective disclosure and proof of innocence mechanisms, allowing users to provide specific proofs to compliance agencies or tax authorities without disclosing data to the public, in response to anti-money laundering regulatory requirements.Vitalik believes that the public transparency of blockchain is the main obstacle preventing cryptocurrency payments from replacing traditional payments, and the ZK payment standard aims to make privacy a default feature.

According to token unlocking data from the Crypto asset data platform RootData, zkSync (ZK) will unlock approximately 173.14 million tokens at 0:00 on May 17, Beijing time, worth about 3.23 million USD.

ChainCatcher reports live from the 2026 Hong Kong Web3 Carnival, where Ethereum co-founder Vitalik Buterin delivered a keynote speech. He defined Ethereum by two core functions: first, as a public bulletin board for applications to publish messages and data; second, as shared digital objects controlled by code, encompassing assets, NFTs, ENS, and DAOs. He emphasized that Ethereum's goal is not to compete with high-frequency trading platforms on speed, but to become the most secure, decentralized, and always-online trusted chain.Regarding the short-term roadmap, he introduced the account abstraction proposal EIP-8141, which natively supports smart contract wallets, quantum-resistant signature algorithms, and privacy protocols; in terms of quantum resistance, there are currently two signature schemes based on hash and lattice, and the team is significantly enhancing their efficiency through EVM vectorization.He revealed that ZKVM is fast enough to prove real-time EVM execution, with this year's goal being to ensure its security, planning to start deployment from a small proportion of the network, aiming to become the primary method of validation by 2028, allowing Ethereum to scale significantly without sacrificing decentralization. In terms of long-term vision, Ethereum is actively utilizing AI to generate mathematical proofs to formalize software security verification, pursuing complete quantum safety and maximum simplicity to ensure platform security does not rely on the continuous existence of any single team.
