Ethereum plans to achieve a quantum-safe L1 by 2029, with the Hegotá upgrade roadmap taking shape.

According to The Block, the Ethereum Foundation Protocol Cluster has released a list of EIP ratings for the upcoming Hegotá upgrade, setting December 2029 as the target milestone for achieving full quantum resistance. The two S-tier (mandatory delivery) proposals for the upgrade are: FOCIL (EIP-7805) at the consensus layer, which enhances censorship resistance by requiring validator committees to enforce the inclusion of public mempool transactions; and framework transactions (EIP-8141) at the execution layer, which natively integrates account abstraction, supporting custom signatures, sponsored gas, and batch operations to improve security and quantum resistance. The Ethereum Foundation stated that this timeline aligns with the independent migration targets of Google, Cloudflare, and Microsoft, and the December 2029 deadline will be considered non-negotiable prior to January 2027. Hegotá is not the final quantum-safe fork, but rather a critical milestone determining whether subsequent upgrades can proceed on schedule. From the Q4 2026 Glamsterdam upgrade to December 2029, the average fork cycle is only about 7.2 months, leaving extremely limited execution slack.

JaredfromSubway.eth sandwich attack bot has extracted $295 million in total, with $7.5 million stolen in June

Odaily News: The sandwich attack bot operated by JaredfromSubway.eth has extracted a cumulative total of 117,007 ETH since March 2023, worth approximately $295 million at current prices. In June 2026, an anonymous attacker deployed 66 counterfeit token contracts, exploiting the bot's automated trading logic to steal at least $7.5 million in ETH and stablecoins, and funneled the funds into Tornado Cash. The stolen assets have not yet been recovered.Sandwich attacks are a form of Maximal Extractable Value (MEV): the bot monitors large transactions in Ethereum's public mempool, buys ahead of the target transaction, and sells after the transaction pushes the price up, capturing profits from the spread. The bot's primary contract had received a cumulative total of 117,007 ETH as of August 28.MEV-Boost block construction is centralized among a small group of participants, with relay.ultrasound.money, Titan Relay, and bloXroute regulated relays collectively forwarding approximately 85% to 88% of related blocks within a 24-hour window; Titan's builder independently assembled 50.3% of the blocks. Monthly sandwich attack extraction amounts have declined from approximately $10 million in late 2024 to roughly $2.5 million in October 2025. (Bitcoin.com News)
