What Are Smart Contracts? How Do They Work, and Why Do Risks Still Exist?
In the Web3 world, smart contracts are the foundation of many blockchain applications. From DeFi lending to NFT trading, many operations rely on code that executes automatically. But smart contracts are not absolutely secure. Understanding how they work is key to seeing the risks behind their efficiency.
First, what is a smart contract?
A smart contract is a program deployed on a blockchain that processes transactions and state changes according to predefined rules. It is not a legal contract in the traditional sense, no

BTC Fund Flows Return, While ETH Remains Under Heavy Selling Pressure
BTC spot ETFs have resumed net inflows, but ETH spot ETFs continue to see substantial outflows, with institutional capital clearly favoring BTC.
The overall structure for both remains weak, but both are near short-term lows, so don't chase shorts.
【BTC Strategy】
Direction: Short on a rebound
Entry: Resistance at 80100—80250, followed by a pullback from the highs
Target 1: 79600
Target 2: 79000
🔴 Stop-loss: Above 80500
【ETH Strategy】
Direction: Short on a rebound
Entry: Fails to hold above 2320—2332 and weakens again

$Q Volume continues to contract as prices keep falling—the chance for trapped long positions to break even is here!
The price surged 330% in less than a day, and anyone who entered anywhere near the bottom made a killing. Most of you may have gone short along the way and ended up trapped halfway up. The chance to get out is finally here. That’s how altcoins are: market makers won’t pass up a chance to trap anyone blindly trying to pick tops and bottoms. Only by following the trend can you profit steadily and stay in control. This pullback has already turned into a one-way move.

U.S. stocks are up, Japanese stocks are up, Korean stocks are surging, and only A-shares are making a serious effort to fall. Is this what they call “resilience”? A textbook case of following the declines but not the rallies. You have to hand it to them. 📉👋

$ETH is currently at 2304.19, down 0.78% over 24H. The 1H trend is weak compared with the weak 4H trend. Watch whether it can hold above resistance at 2344.72 and reclaim support at 2295.88 if it breaks below. Volume is only 0.29x the average. The market is volatile; for observation only.

#宏观关键周 Interest Rate Decisions vs. Tech Earnings—Which Moves Markets More?
‌The impact of Federal Reserve interest rate decisions far outweighs that of any single tech giant’s earnings report‌; they are currently the core market-wide driver.
Interest rate decisions directly determine how tight or loose dollar liquidity is, affecting nearly all major asset classes, including US stocks, crypto, and gold, and serving as the market-wide pricing benchmark.
Tech earnings from companies like Microsoft affect only the companies themselves and related AI-chain assets; their reach across the broader mar

Gold prices have been looking good these past couple of days, so I’ve started allocating to gold again. But when you hold gold, do you just wait for the price to rise? Are there any other uses for it?
Absolutely! Unlike simply tokenizing gold and silver, the HardFi built by @strato_net aims to create an on-chain financial system centered around real-world assets. The project has issued two metal tokens, $GOLDST and $SILVST , backed by physical reserves. They can be used directly as CDP collateral to mint the dollar-pegged stablecoin $USDST. The overall logic is much like the DeFi collateraliz
