+
+在本教程中，我们将介绍如何使用 Ethers.js 完成一个钱包地址监控的脚本
+
+### **什么是聪明钱？**
+
+在加密领域，聪明钱（Smart Money）是指**拥有专业知识、对市场有深入了解以及具有信息优势的专业投资机构或个人投资者**。 聪明钱一直以来都是加密市场中的**关注焦点**，因为这些实体通常可以获得普通交易者不易获得的**信息和资源**，他们有着丰富的交易经验和优异的历史业绩，投资理念成熟，这可能使他们在存在**严重信息不对称**的加密货币市场中占据优势。
+
+
+
+因为在区块链中所有数据都是公开的，我们可以看到所有人的交易数据。所以我们可以对历史成绩比较优秀的钱包地址进行监控。第一时间知道这些聪明钱的动向。
+
+
+
+## 聪明钱监控
+
+首先配置需要监控的钱包的地址，这里我们监控V神的钱包地址
+
+```js
+// 配置
+const WALLET_ADDRESS = `0x220866B1A2219f40e72f5c628B65D54268cA3A9D`;
+
+const ALCHEMY_GOERLI_URL = 'https://eth-mainnet.g.alchemy.com/v2/abWt0F-bY-Z4Amf_xOU_QQLftkhLU4cO';
+const provider = new ethers.JsonRpcProvider(ALCHEMY_GOERLI_URL);
+```
+
+然后获取当前的eth余额记录下了
+
+```js
+// 获取初始余额
+let previousBalance = await provider.getBalance(WALLET_ADDRESS);
+console.log(`初始余额: ${ethers.formatEther(previousBalance)} ETH`);
+```
+
+监听链上的新区块，如果有转账或者是合约交互的话进行提醒。
+
+```js
+// 监听新区块
+provider.on('block', async (blockNumber) => {
+    console.log(`新区块: ${blockNumber}`);
+
+    // 检查余额变化
+    const currentBalance = await provider.getBalance(WALLET_ADDRESS);
+    if (currentBalance !== previousBalance) {
+        console.log(`余额变化: ${ethers.formatEther(currentBalance)} ETH`);
+        previousBalance = currentBalance;
+    }
+
+    // 获取区块
+    const block = await provider.getBlock(blockNumber);
+
+    // 检查交易
+    if (block && block.transactions) {
+        for (const txHash of block.transactions) {
+            const tx = await provider.getTransaction(txHash);
+
+            if (!tx) continue;
+
+            if (tx.from && tx.from.toLowerCase() === WALLET_ADDRESS.toLowerCase() ||
+                (tx.to && tx.to.toLowerCase() === WALLET_ADDRESS.toLowerCase())) {
+
+                console.log(`检测到交易: ${tx.hash}`);
+                console.log(`从: ${tx.from}`);
+                console.log(`到: ${tx.to || 'Contract Creation'}`);
+                console.log(`金额: ${ethers.formatEther(tx.value)} ETH`);
+
+                // 检查是否是合约交互
+                if (tx.data && tx.data !== '0x') {
+                    console.log('检测到合约交互');
+
+                    // 获取交易收据以查看事件日志
+                    const receipt = await provider.getTransactionReceipt(tx.hash);
+
+                    if (receipt && receipt.logs) {
+                        console.log(`事件日志数量: ${receipt.logs.length}`);
+
+                        for (const log of receipt.logs) {
+                            console.log(`  事件主题: ${log.topics[0]}`);
+                            console.log(`  合约地址: ${log.address}`);
+                        }
+                    }
+                }
+
+                console.log('---');
+            }
+        }
+    }
+});
+```
