Google Engineer Charged Over $1.2M Insider Trades on Polymarket
US prosecutors have charged a Google software engineer, Michele Spagnuolo, with allegedly using confidential internal search data to place trades on Polymarket and earn around $1.2M in profit.
Authorities say he made at least 20+ trades linked to Google search trend outcomes, wagering millions of dollars and benefiting from information that had not yet been publicly released. The trades reportedly generated over $1.2M in gains once the official Google data was published.
The U.S. Department of Justice has charged him with commodities fraud, wire fraud, and money laundering, while the CFTC filed a parallel civil case. If convicted, he faces decades in prison.

US prosecutors have charged a Google software engineer, Michele Spagnuolo, with allegedly using confidential internal search data to place trades on Polymarket and earn around $1.2M in profit.
According to the DOJ complaint, Spagnuolo accessed non-public “Year in Search” data from Google and used it to predict outcomes in Polymarket markets, including bets on the most-searched people of 2025. He allegedly traded under the alias “AlphaRaccoon” between October and December 2025.

THORChain Hit by $10.7M Exploit. 5 of 6 Vaults Survived
This attack was carefully prepared over weeks, not executed overnight. Chainalysis traced the attacker’s setup back to late April, when a linked wallet moved XMR through a privacy bridge, swapped into USDC, bridged to Ethereum, and bonded RUNE on THORChain to operate as a legitimate validator before executing the exploit.
THORChain detected abnormal balances within minutes and halted the network through validator coordination and emergency governance actions, without any central authority. Only 1 of 6 Asgard vaults was breached: $10.7M was drained, while the remaining vaults, LP positions, and user funds were unaffected.

The attack targeted THORChain’s GG20 threshold signature scheme, where validators jointly sign transactions using split key shares. By exploiting a flaw in the implementation, the attacker gradually extracted enough key material to reconstruct private key and bypass signing process.

Vitalik Buterin to Write Sci-Fi Novel on Decentralized Governance Themes
Ethereum co-founder Vitalik Buterin has announced a creative shift, stepping away from his usual long-form technical essays to write a science fiction novel focused on decentralized governance.
Buterin has been one of the most influential voices in crypto theory, known for deep dives into Ethereum design, voting mechanisms, and decentralized decision-making models.
The new sci-fi approach allows him to explore these concepts in fictional societies, testing governance structures through characters, conflict, and world-building rather than formal analysis.

Ethereum co-founder Vitalik Buterin has announced a creative shift, stepping away from his usual long-form technical essays to write a science fiction novel focused on decentralized governance.
The announcement was made via his Farcaster account, where he shared that the novel is already completed through at least its first two chapters and is available in draft form. The project continues his long-standing exploration of governance systems, DAOs, and crypto-economic coordination, but through a narrative format instead of analytical essays.

At launch, VBNB will not engage in staking, meaning performance reflects only BNB's price appreciation less fees, which may cause the ETF to lag the returns of direct BNB holders who participate in staking.

Aave Labs Secures Dual FCA Approvals To Build Regulated Crypto Payments Infrastructure In UK
The approvals allow Aave Labs to develop regulated fiat-to-crypto payment infrastructure, including a planned zero-fee on- and off-ramp that would let users move funds directly from bank accounts into Aave without leaving the app.
The expansion follows Aave Labs’ broader European regulatory push. In November 2025, its Irish subsidiary secured a MiCA Crypto-Asset Service Provider license from the Central Bank of Ireland, unlocking passporting rights across the European Economic Area.
Aave Labs is the main contributor to Aave, currently the largest onchain credit market by total value locked. The company is also advancing Aave V4 and the GHO stablecoin following a $25M funding grant approved by the Aave DAO earlier this year.

When both agree, withdrawal finality can drop to as little as one day, while permissionless ZK proofs can override permissioned TEE proofs in case of conflicts.
