+
+## 实现原理
+
+Epusdt 通过监听多条区块链网络（TRC20、ERC20、BEP20、Polygon 等）的 API 或 RPC 节点，实时捕获钱包地址的代币入账事件，利用**金额差异**与**时效性**精确匹配交易归属：
+
+```text
+工作流程：
+1. 客户发起支付，需支付 20.05 USDT
+2. 系统在哈希表中查找可用的钱包地址 + 金额组合
+3. 若 address_1:20.05 未被占用 -> 锁定该组合（有效期 10 分钟），返回给客户
+4. 若已被占用 -> 自动累加 0.0001 尝试下一个金额组合（最多 100 次）
+5. 后台线程持续监听所有钱包的入账事件，金额匹配则确认支付成功
+```
