Ride high, fall big. Hyperliquid was riding high, dazzling tens of thousands with its points-based rewards, dishing out airdrops to over 94,000 wallets, and clocking in a cool $3.5 billion in trading last week.

Enter stage left, a hacker with a taste for drama and an appetite for millions, ready to rewrite the script.

Calculated strike

Blockchain sleuths at PeckShield dropped the bombshell, and shared that some shadowy villain snatched a private key connected to Hyperliquid’s Hyperdrive lending protocol.

The loot? Nearly 18 million DAI stablecoins, plus a juicy 3 million SyrupUSDC, USDC’s funky cousin, vanished into the Ethereum abyss.

How the key got exposed? A mystery wrapped in blockchain enigma, but on-chain clues suggest a cold, calculated strike.

This is a reminder that in DeFi’s grey zone, private keys are the kingpins. Lose ‘em, and you lose everything. No sheriffs, no judges, just cold, irreversible blockchain justice.

Even the pros slip

Hyperliquid’s exploit arrives as decentralized platforms gather glory, yet simultaneously reveal their Achilles’ heels.

The promise of self-custody and freedom comes with the price tag of eternal vigilance. Even the pros slip, one careless click, one fake authorization page, and boom, millions flee.

Phishing scams and fake support accounts remain prime villains in this story.

The ironic twist is that Hyperliquid’s docs aren’t shy about the golden rule, guard your private keys like your life depends on it. Because here, it does.

Stay alert

Cybersecurity watchdog CertiK’s latest figures read like a horror story for crypto fans. 2025’s hacks keep prey focused squarely on decentralized platforms and exchanges, bleeding millions from the scene.

For Hyperliquid, this hack stings far beyond the lost millions. A platform’s reputation, the lifeblood of trust in DeFi, took a hit just as it was hitting its stride.

The story continues, but one thing’s already crystal clear, DeFi freedom rides on razor-sharp security.

Guard those keys, guys, or the blockchain’s cold hand might snatch your crypto dreams away.

In the grand DeFi narrative, freedom flexed, but security ignored often ends in chaos. Stay alert. The next plot twist is always just a transaction away.

After the US October CPI exceeded expectations, Goldman Sachs and Nomura added a forecast for an interest rate hike in March next year, while Deutsche Bank included a forecast for a rate hike in January next year. Currently, the market has fully priced in a 25 basis point rate hike in December, with a 13% probability for a 50 basis point hike. On Wednesday, the US Treasury spot market was closed, but Treasury futures continued to fall, with corresponding yields rising by about 2 to 4 basis points, and spot gold came under pressure, dropping by 1.1%.

No Need to Worry About the Cooling Down of AI Data Center Construction? The US Import Boom Is Unlikely to Subside in the Short Term, Real Impact May Come in 2029

It takes an average of 4.8 years from finalizing investment to starting construction of a data center project, and an additional 2.6 years from construction start to becoming operational. Servers usually cannot be installed until after the building structure and racks are completed. For trade partners such as Taiwan (China), South Korea, and Mexico who rely on US data center supply chain demand, the inertia in construction timelines provides at least a one- to two-year buffer for future exports.

Federal Reserve Major Debate: When Should the Tenure of “Number Three” Williams End?

The main point of contention is whether Williams should step down in June 2028, upon completing a full 10-year term, or in June 2027, when he reaches the mandatory retirement age of 65. Analysts point out that the Federal Reserve Board holds ultimate discretion; if he leaves early, Fed Chair Waller would be able to assert greater control over the appointment to this critical position. However, forcing Williams to shorten his term could easily be interpreted as political manipulation. Williams himself is expected to serve until June 2028.
