Uniswap V4 的 Hooks 到底是什么？为什么叫做钩子？

在编程世界里，Hook” 是一个经典术语，指在系统主流程的特定挂钩点上，允许外部代码像钩子一样挂上去执行自定义逻辑，而无需修改核心代码本身。

我们可以把 Hooks 理解为附着在每个流动性池上的小程序或智能触发器。开发者可以预先设定规则，让资金池在特定时刻自动执行操作。

例如，在交易前检查参与者资格，在交易时根据市场波动动态调整手续费，或在交易后自动将收益进行复投。

这赋予了原本被动的资金池以自主决策能力，使其从一个简单的流动性容器，进化成一个拥有自定义逻辑的智能体。

这种可编程性，为 DeFi 应用打开了前所未有的设计空间。

我们也可以把 Uniswap 的流动性池想象成你家里墙上那些普通的电源插座。
在 V3 时代，这些插座功能是固定的：只能插标准插头，输出固定功率的电。你想接个智能音箱让它定时开关？想接个感应器实现人来灯亮？对不起，插座本身做不到。

而 Hooks，就是给每个这样的“电源插座”（流动性池）都安装上一个万能智能转换器。这个转换器自带“大脑”（一小段可编程代码），允许你自定义规则。

比如，你可以设定：
1. 在用电前，先检查是不是我家授权的电器（白名单检查）；
2. 在用电时，根据当前电网负荷自动调节电费单价（动态费用）；
3. 用电结束，自动把节省的电费存入我的理财账户（自动复投）。

这样一来，每个原本功能单一的“插座”，就变成了能执行复杂、智能任务的“智能终端”。开发者也不需要去重建整个房子（分叉整个协议），只需要设计不同的“智能转换器”（Hooks），就能让同一个基础插座实现智能家居、节能计划、安全监护等无数新功能。
这就是 Hooks 带来的根本性改变：将固定的基础设施，变成了可编程、可定制的开放平台。

另外一点，
2025 年底通过的 UNIfication 治理提案，其核心是激活了协议中沉睡多年的价值捕获引擎——费用开关。
这意味着，Uniswap 协议产生的部分交易手续费，将不再全部归属于流动性提供者，而是会以程序化的方式分配给 $UNI 的持有者。
具体而言，协议将在交易手续费中抽取一定比例作为协议收入。
此举为 UNI 代币注入了关键的现金流预期，使其从一个仅代表治理权的符号资产，转变为一个能够直接捕获协议价值的生息资产。

这两大演进共同标志着 Uniswap 正在进化为一个拥有强大可组合性与价值积累能力的 DeFi 生态基石。

I remember the first time I tried to use a DEX.
I opened the app. Stared at the screen. Closed it.
It felt like it wasn't built for me.
That feeling is exactly why I'm writing this. Because STON.fi actually changed that experience for me and if you're new to TON DeFi, I want to show you just how simple your first swap really is.
Four steps. That's all it takes.
Step 1 : Connect Your Wallet
Open STON.fi at app.ston.fi and tap Connect Wallet.

Tonkeeper, TON Wallet, or any WalletConnect supported wallet works perfectly. No complicated setup. No new accounts to create.
Honestly the first time I connected it took me less than 30 seconds. You connect once and just like that you're inside TON DeFi.
Step 2 : Select Your Token Pair
Choose what you're sending and what you want to receive.

Search by name or paste the contract address directly. Your available balance shows up automatically no switching tabs, no manual checking.
One thing worth knowing here, STON.fi shows token warnings like "Fake" or "Honeypot" right before you swap. Built-in protection before you even move a single token. That's the kind of detail that actually protects beginners.
Step 3 — Enter Your Amount
Type in how much you want to swap.

No minimum. No barriers. Whether it's $1 or $1,000, STON.fi shows you exactly what you'll receive, the fees, slippage and route all before you touch anything.
Take your time. Look at the numbers. When you're comfortable move to the final step.
Step 4 : Confirm and You're Done
Review everything one more time. Hit Confirm Swap. Approve in your wallet.
And just like that. It's done. Your first TON DeFi swap complete. 🎉
Powered by Omniston, STON.fi's liquidity routing protocol that finds you the best available price across the entire TON ecosystem automatically.
Why this matters:
TON DeFi just hit $40M in a single day of swap volume. One swap every 0.73 seconds. The ecosystem is growing fast.
And the best time to learn how to use it is before everyone else figures it out.
If you know someone who's been putting off trying TON DeFi because it feels complicated share this with them. It's simpler than they think.
🔗 Try your first swap: app.ston.fi
Not financial advice. Always conduct your own research before making any investment decisions.

🔥 $ETH Sits at a Make-or-Break MA Convergence — BlackRock Just Doubled Down

📰 Last 24h Highlights:
• BlackRock launched two tokenized money-market funds directly on Ethereum (May 9), reinforcing institutional conviction in ETH as the backbone of tokenized finance
• Spot ETFs pulled in $271.6M May 1–6 before a $103.5M outflow on May 7 — mixed signals as staking-enabled products await further SEC approval ($BTC ETFs also saw volatile weekly flows)
• Glamsterdam upgrade devnet-5 is live — devs agreed on 200M gas/block (3× current capacity), targeting Q3 2026 mainnet activation
• Whales accumulated 140,000+ ETH (~$322M) in 96 hours, pushing holdings to ~13.98M ETH — price still range-bound, awaiting broader participation

📊 Technical Read (today, approximate):
• Spot: ~$2,329 (+0.7% 24h) — range $2,300–$2,337
• RSI 14: daily ~55, 4H ~58 — neutral territory, no extremes
• MACD daily: histogram slightly negative but contracting — bullish crossover forming
• 50 EMA (~$2,317) and 200 EMA (~$2,324) converged into a $7 band — $ETH is sitting directly inside this convergence zone right now. Daily close above $2,383 would flip both to support
• Bollinger squeeze: upper $2,383, mid $2,314, lower $2,245 — classic volatility compression signals imminent breakout
• Spot volume ~$11B (below 20d avg); funding near-zero; OI $33B declining — de-leveraged, coiled market

🧠 Short-Term View:
$ETH is coiled at the 50/200 EMA convergence with a Bollinger squeeze — a textbook pre-breakout setup. Fundamentals are constructive: BlackRock tokenizing directly on Ethereum, whale accumulation accelerating, Glamsterdam promising to triple execution capacity. But the network remains mildly inflationary (~0.23%/yr) and the KelpDAO exploit ($292M) still weighs on the restaking narrative. A daily close above $2,383 confirms bullish resolution toward $2,420–$2,550. Below $2,300 exposes $2,200.
