const ConditionalToken = await hre.ethers.getContractFactory("ConditionalToken"); const token = await ConditionalToken.deploy(); await token.deployed(); console.log(`合约部署成功: ${token.address}`); https:// 示例：创建一个USDC市场 const USDC_ADDRESS = "0x你的链上USDC地址"; const tx = await token.createMarket(USDC_ADDRESS); await tx.wait(); console.log("市场创建完成");}main().catch((error) => { console.error(error); process.exitCode = 1;});```---## 核心功能说明（对应 Polymarket 逻辑）### 1. ERC-1155 铸造逻辑- **YES 代币 ID** = `市场ID * 2`- **NO 代币 ID** = `市场ID * 2 + 1`- 铸造：用户抵押 1 USDC → 获得 **1 YES + 1 NO**- 销毁：用户归还 **1 YES + 1 NO** → 赎回 1 USDC### 2. 代币状态管理（完整状态机）| 状态 | 含义 | 允许操作 ||------|------|----------|| CREATED | 市场开放 | 拆分、合并、交易 || LOCKED | 交易停止 | 禁止铸造/销毁 || SETTLED | 已结算 | 销毁胜选代币 → 兑奖 || CANCELLED | 已取消 | 全额退款 |### 3. 结算逻辑- 预言机上报结果 → 合约标记**胜选代币**- 用户调用 `redeemWinnings()`： - 自动销毁**胜选代币** - 按 1:1 比例兑换 USDC 到钱包 - 防重复赎回校验---## 交付标准（生产可用）1. **依赖版本** - Solidity 0.8.20+ - OpenZeppelin Contracts 5.0+ - 支持 Polygon/Arbitrum/Base 低Gas链2. **安全特性** - `ReentrancyGuard`：防重入攻击 - `Ownable`：管理员权限控制 - 状态严格校验：禁止非法操作 - 防重复赎回：`isTokenRedeemed` 标记3. **可直接对接** - 链下订单簿（CLOB） - 预言机（UMA/Chainlink） - 前端钱包交互（WalletConnect）---## 你接下来需要我补充什么？我可以**直接交付完整工程**，包括：1. 测例（单元测试+集成测试）2. 前端 ABI + 调用示例3. 预言机对接代码4. 审计优化版合约告诉我你的部署链（Polygon/Base）即可！
