+## 本次修复内容（v2→v3）
+
+### 新增功能
+1. **trc20_intents表**：新增数据库表，存储用户预注册的EVM地址意向
+2. **EVM地址自动匹配**：TRC20 Monitor检测到新交易时，自动通过TRON发送地址匹配已注册的EVM地址意向
+3. **管理员EVM Intents标签**：后台新增标签页，显示所有预注册EVM地址（含匹配状态）
+4. **registerTrc20Intent改进**：现在将EVM地址存储到数据库，而不仅仅返回收款地址
+
+### 修复问题
+- 修复TRC20面板EVM地址提交后未持久化到数据库的问题
+- 修复Admin后台无法查看EVM地址意向的问题

+- 已售出：**495,000 XIC**
+- 购买记录：**1笔**（状态：Confirmed，待发放XIC）
+- 进度：**0.2%**（目标$5,000,000 USDT）

+
+## 已知限制（不影响核心功能）
+
+1. **vite unhandledRejection**：生产环境不调用vite，仅import时报非致命警告，不影响功能
+2. **TRC20 Monitor网络超时**：TronScan API偶发超时，自动重试，已确认数据不受影响
+3. **BSC/ETH链上数据**：合约地址为测试地址，实际部署时需替换为正式合约地址
