Accept that some of the old pleasures may not return, such as the simple satisfaction of writing code and watching it compile successfully.

Here it is！

[Claude @claudeai]

Introducing Claude Opus 4.7, our most capable Opus model yet.

It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.

You can hand off your hardest work with less supervision.

The Golden Rule of Assertions, article https://t.co/aP0kt63nLe

"A test must fail if, and only if, the intention behind the system is not met."

📌 Key Takeaways:
- Focus on Intention, Not Implementation
- Define Clear Test Boundaries
- Use Mocking to Establish Boundaries
- The "When" Matters

用wagmi之前，最好先熟悉一下Tan Query https://t.co/nFMZIIrVUB

今天实现了Swap，又是烧脑的一天

📌 基础踩坑
- ETH swap 要传 value参数
- Token swap 要先 approve 再 swap
- 先查 allowance 省掉多余授权交易
- USDC → ETH 实际拿到的是 WETH（Uniswap 内部用 WETH）

���� 费率用整数表示
fee = 500 → 0.05%
fee = 3000 → 0.3%
fee = 10000 → 1%

公式：实际费率 = fee / 1,000,000
避免浮点数精度问题 💡

📌 Q96 定点数
用 uint160 存储价格：
- 前 64 位：整数部分
- 后 96 位：小数部分（精度 2^96 ≈ 7.9×10^28）

编码：encoded = value × 2^96
解码：decoded = encoded / 2^96

SDK 工具函数：encodeSqrtRatioX96(numerator, denominator)

📌 最反直觉的坑：sqrtPriceLimitX96
Uniswap V3 存的是 √price，而且 price = token1 / token0

以 ETH/USDC 池子为例：
- USDC (0xA0b8...) = token0
- ETH (0xC02a...) = token1
- price = ETH/USDC = 1/2000 = 0.0005

当 ETH 从 2000 涨到 2100：
❌ 直觉：price 变大
✅ 实际：price = 1/2100 < 1/2000，变小了！

📌 关键细节
token0/token1 按地址字典序排序：
0xA0b8... < 0xC02a...
所以 USDC 是 token0，ETH 是 token1

永远先确认 token 顺序，否则方向全反！

📌 确认参数和返回值结构花了大量时间，如何高效阅读技术文档？
