A major crypto exchange reported a $6.3 billion security incident. See how the platform responded and how the industry helped freeze funds.

That detail quickly pushed EIP-7702 into the center of the discussion. The Ethereum account-delegation mechanism allows a normal externally owned account, or EOA, to temporarily execute smart contract logic. In the Binance incident, blockchain researchers identified an EIP-7702 delegation shortly before assets were transferred from a Binance-linked hot wallet. But there is an important distinction

The Binance security incident on October 30, 2026 has pushed a relatively technical Ethereum feature into a much broader security discussion: EIP-7702 wallet delegation.

It is whether the same class of authorization risk could affect a personal wallet holding ETH, USDT, USDC or other Ethereum assets

Eli Lilly stock hit a record high after earnings. See what drove the rally, what the headline numbers hide and what LLY investors should watch.

Aave adjusted the USDT variable borrowing interest rate model on its V3 Ethereum Core market on October 21, 2026, lowering the optimal utilization threshold from 94% to 92%. The change followed a recommendation from risk service provider LlamaRisk and was executed at Ethereum block 26,241,799. The base rate and the two principal interest rate slopes remained unchanged, meaning the update altered when borrowing costs begin accelerating rather than introducing a uniform rate increase

Avail expanded access to ShieldTX, a privacy-focused trading tool for Hyperliquid, on October 28, 2026, targeting a problem emerging from transparent perpetual futures markets: automated systems can identify successful wallets, monitor their positions, and replicate their trading activity. ShieldTX attempts to reduce this exposure by creating separate wallets for individual positions, making it harder for public observers to connect a trader's broader portfolio with specific transactions. The expanded release remains invitation-based rather than fully open to all users

Google stock fell about 10% after Alphabet’s Q3 earnings. The key issue was not weak AI demand, but rising capex and negative free cash flow.

Kalshi and S&P Dow Jones Indices (S&P DJI) announced a strategic collaboration on October 26, 2026, connecting established financial benchmarks with prediction-market products and data. Under the agreement, Kalshi becomes a preferred prediction-market platform licensed to offer event contracts tied to S&P DJI indices, while S&P DJI becomes a preferred provider for creating new indices derived from Kalshi event-market data. The collaboration introduces two distinct commercial opportunities: using recognized financial indices to settle event contracts and transforming prediction-market expectations into standardized information products

Payward, the parent company of Kraken, is pursuing a regulated pathway for bringing onchain perpetual futures to U.S. customers through Hyperliquid's HIP-3* infrastructure. The company announced its plan on September 16, 2026, while Hyperliquid's October 26 update drew renewed attention to the proposed permissioned market architecture. Under the arrangement, Bitnomial would operate the exchange and clearing functions, NinjaTrader Clearing would maintain customer accounts, and Hyperliquid would supply the blockchain-based order book used to execute and record transactions

DeFi price manipulation attacks have reached a new reported annual high in 2026, exposing persistent weaknesses in how decentralized financial protocols value assets, manage collateral, and respond to abnormal market conditions. According to DefiLlama data cited by RootData and other industry publications, 43 price manipulation incidents had been recorded by October 21, surpassing the previous full-year high of 27 incidents in 2022. Reported losses associated with the 2026 incidents totaled approximately $199 million, although their distribution reveals a more complex security picture than the headline count suggests
