#这套合约能实现什么？（完整Polymarket核心）
###✅预测市场全流程
1.**创建市场**→自动生成YES/NO代币
2.**用户抵押USDC**→获得1YES+1NO
3.**链下交易**（你自己做订单簿）
4.**锁定市场**→停止交易
5.**预言机上报结果**
6.**用户赎回奖金**
7.**支持取消退款**
###✅安全机制
-重入防护
-状态机严格控制
-防重复兑奖
-预言机权限隔离
-管理员风控

#快速部署（1分钟）
##1.安装依赖
```bash
npminit-y
npminstall@openzeppelin/contractshardhat
npxhardhatinit
```
##2.放入合约
`contracts/PolymarketPlatform.sol`
##3.部署脚本
```jascript
consthre=require("hardhat");
asyncfunctionmain(){
constPM=awaithre.ethers.deployContract("PolymarketPlatform");
awaitPM.waitForDeployment();
console.log("部署完成:",awaitPM.getAddress());
}
main();
```
##4.运行
```bash
npxhardhatrundeploy.js--networkpolygon
```
