According to The Information, the IPO process of AI chip company Cerebras Systems has once again attracted market attention, with key beneficiaries including Foundation, well-known venture capital firm Benchmark, and OpenAI.Cerebras has long been seen as a potential competitor to Nvidia, dedicated to developing ultra-large-scale AI chips, but its commercialization process has faced setbacks. The company withdrew its IPO prospectus in 2025, causing its listing plans to stall for a time. However, as the AI infrastructure boom continues to heat up, the market is refocusing on its potential listing value and early investor returns. Early investment firms, including Benchmark, as well as OpenAI, which has a partnership with the company, may gain substantial benefits from Cerebras' future listing.

The TAC team announced that its cross-chain layer's TON side was exploited by external attackers, resulting in a loss of approximately $2.8 million, involving USDT, BLUM, and tsTON. TAC, TON, and all ERC-20 tokens bridged from Ethereum are unaffected. The bridging service remains suspended, and forensic analysis and repair work are ongoing. A complete report with more details will be released within the next 48 hours.The team is actively collaborating with law enforcement, SEAL 911, and security partners to track and freeze the stolen funds. The team stated that its core focus is to sell the foundation's TAC token reserves in a legally structured manner to compensate for user losses and fully restore bridging liquidity. Official channels will continue to update progress.

The Ethereum Foundation officially launched the Clear Signing open standard on Tuesday, aimed at replacing the unreadable hexadecimal strings displayed when wallet users sign transactions with human-readable transaction content.This standard is centered around ERC-7730. When a wallet supports this standard, it will read the descriptor file of the contract and reconstruct the raw transaction data into understandable content, such as displaying a Uniswap V3 swap as sending 1,000 USDC and receiving at least 0.42 WETH. ERC-8176 adds an integrity certification layer on top of this, allowing auditors to publish signature certification confirming the accuracy of the descriptors. Participants include hardware wallets (Ledger, Trezor), software wallets (MetaMask, WalletConnect), security companies (Cyfrin), and infrastructure (Fireblocks), among others.Blind signing has been a significant cause of losses in crypto assets. The $1.5 billion vulnerability at Bybit in February 2025 and the approximately $235 million WazirX incident both involved signers approving transactions that did not reflect the true intent. Ledger initiated this project in 2021, formalized it as ERC-7730 in 2024, and transferred governance to the foundation earlier this year to ensure the neutrality of the standard. The ERC-7730 V2, released in April 2026, has expanded its coverage to cross-chain use cases, software wallets, and confidential token primitives.

The Ethereum Foundation unstaked 21,271 ETH from Lido, triggering market panic. Arkham published an analysis stating that the foundation's move may be due to concerns about the security of third-party protocols.In addition, the foundation has recently sold ETH multiple times, indicating a need for treasury rebalancing, which typically would not lead to immediate selling.

The Ethereum Foundation has appointed three new co-leads, Will Corcoran, Kev Wedderburn, and Fredrik, to lead the main protocol cluster. The team handover work is now fully underway. The focus for the future is to release Glamsterdam, continue preparations for Hegotà, and advance Strawmap.

The Ethereum Foundation disclosed the results of a recent interoperability meeting held by core developers in the Svalbard archipelago of Norway and updated the key technical progress for the next phase upgrade, Glamsterdam. During the meeting, multiple client teams collaborated on network scalability and execution layer optimization, making progress in several directions. Developers confirmed that based on the comprehensive results of ePBS, BAL optimization, and the EIP-8037 repricing mechanism, a consensus on the "trusted path" after Glamsterdam has been reached.In terms of the execution layer, ePBS (External Proposer Separation Architecture) has been stably running in the multi-client Glamsterdam-devnet, and the external block builder process has completed end-to-end testing, covering almost all client implementations. Meanwhile, EIP-8037 has been finalized, establishing the fixed cost_per_state_byte model, and complete repricing parameter output has been achieved in bal-devnet-6. The scalability direction Hegotá has also made progress. The FOCIL-related prototype has a runnable implementation, and the scope of account abstraction (AA) requirements has been defined, with the next phase entering the multi-client development network verification stage.Current development focus remains on the final implementation of Glamsterdam while advancing the Hegotá scalability design and subsequent Strawmap route evolution. The development network is online, and functionalities such as FOCIL are expected to continue deepening in the next phase of testing. At the organizational level, this interop meeting also marks the formal initiation of leadership structure adjustments within the Protocol Cluster. The new leaders include Will Corcoran, Kev Wedderburn, and Fredrik. Will Corcoran is responsible for zkVM proof and post-quantum consensus coordination, Kev Wedderburn leads zkEVM development, and Fredrik is in charge of protocol security and the Trillion Dollar Security project.Original Protocol Cluster leadership team members Barnabé Monnot and Tim Beiko will gradually step back from management roles, and Alex Stokes is entering a leave period. The foundation stated that during its term, the Protocol has completed modular advancement and facilitated the launch of the Fusaka upgrade (December 2025), introduced PeerDAS, and enhanced mainnet gas capacity.

a16z Crypto published an article explaining the investment logic behind Arc, pointing out that stablecoins have evolved from tools for crypto trading to a core layer of global financial infrastructure, driving the upgrade of blockchain from "application layer finance" to "system-level economic operating systems."The trading volume of stablecoins reached approximately $9 trillion last year, placing them on the same scale as global payment networks like Visa and PayPal. The total supply of US dollar stablecoins has also exceeded $270 billion, with cross-border payments, B2B settlements, and foreign exchange trading becoming the core use cases for stablecoins, gradually making them the "upgrade layer for global capital flows."a16z Crypto stated that the existing blockchain infrastructure is still primarily aimed at crypto-native users and individual developers, lacking native support for large institutional-level demands. The reason for participating in the ecosystem construction related to ARC tokens is mainly due to the gradual on-chain transition of global finance; in the future, only a few public chains will be able to support the "on-chain economic system foundation."

According to Onchain Lens monitoring, the Ethereum Foundation redeemed 21,271 ETH from the Lido stETH withdrawal contract, worth approximately 49.66 million USD.

The MegaETH Foundation announced that the MEGA token buyback plan has officially launched, and the first MEGA buyback has been completed, using funds from all net earnings generated by the issuer of USDm as of the end of April.The official emphasized that USDm is not issued or operated by the MegaETH Foundation or MegaLabs. The current supply of USDm is approximately $480 million, and future MEGA buybacks will be executed using a programmatic mechanism as much as possible, running automatically based on preset rules, rather than being timed by the foundation. The scale of funds available for each subsequent buyback is not fixed and will be influenced by changes in the supply of USDm and the yield of underlying reserve assets.

Aptos Foundation and Aptos Labs announced that they will invest over $50 million to cover first-party products, research, protocol infrastructure, and a strategic fund for trading and AI partners.Aptos stated that Decibel has launched on the Aptos mainnet, with a cumulative trading volume exceeding $1 billion. The market capitalization of stablecoins on the Aptos network has reached $1.93 billion, and the scale of RWA has reached $1.2 billion, with asset management institutions such as BlackRock, Franklin Templeton, and Apollo Global already deployed on the network. Subsequently, Aptos will advance features such as crypto memory pools, FIX and CCXT connections, multi-leader consensus, and confidential perpetual trading.

Google Cloud and the Solana Foundation have jointly launched a payment system for AI agents called Pay.sh, which supports on-demand payment of API call fees on the Solana chain using stablecoins. This system is based on the x402 protocol incubated by Coinbase, allowing AI agents to discover, invoke, and pay for API resources without the need to register an account or subscribe to services, achieving a "pay-as-you-go" micropayment model.It is reported that AI agents can bind a Solana wallet as an identity identifier and automatically complete payments by recharging their balance with stablecoins or credit cards when invoking cloud services such as data analysis and model inference. Pay.sh operates on top of Google Cloud and connects backend services through an API proxy layer, such as large model calls and container applications. In addition, the system is compatible with the Machine Payments Protocol (MPP) and connects to over 50 API service providers, covering scenarios such as communication, e-commerce, and on-chain data. Officials state that this model helps promote the development of the "Agentic Economy," enabling AI agents to autonomously consume and invoke internet services.

The Ethereum Foundation published a summary of the Soldøgn Interop work, which has now basically completed the key goals of the Glamsterdam upgrade, including reaching consensus on the post-upgrade 200 million Gas Limit lower bound, achieving stable operation of the ePBS external Builder process, and finalizing the EIP-8037 Gas repricing parameters.The focus of the Glamsterdam upgrade is to enhance security by increasing the Gas Limit to expand Ethereum's throughput, while EIP-8037 will prevent state bloat caused by a high Gas Limit by raising the cost of state creation. The Ethereum Foundation also stated that most clients have completed stable operation on glamsterdam-devnet-2 and successfully tested the entire external Builder process. Additionally, substantial progress has been made on FOCIL, native account abstraction, and Hegotá upgrade-related features. In the coming weeks, core developers will continue to advance client hardening, testing improvements, and code merging, with final parameters to be publicly confirmed in the AllCoreDevs meeting.

The Zcash Foundation officially announced the release of Zebra version 4.4.0. This update fixes multiple consensus-level critical security vulnerabilities and strongly recommends that all node operators upgrade immediately. This includes a denial-of-service vulnerability that can cause new blocks to stop being discovered permanently, consensus divergences caused by errors in block signature operation (sigops) counting, anomalies in the processing of transparent transaction signature hashes, and risks of memory allocation amplification attacks.The Zcash Foundation stated that some of these vulnerabilities could cause Zebra nodes to accept blocks that are rejected by zcashd, leading to chain forks. If not updated in a timely manner, nodes may face risks such as interruption in block discovery, consensus forks, and resource consumption amplification, and there are currently no alternative mitigation solutions.
