Polymarket项目开发条件代币合约代币状态管理必备功能速览

Polymarket项目开发条件代币合约代币状态管理必备功能速览我给你一套**Zui简、Zui快、可直接跑**的 **Polymarket 风格代币状态管理搭建方案**，基于 **ERC‑1155**，只保留**核心必须功能**，5 分钟就能跑起来，适合快速搭建 MVP。---# 一、核心设计（极简版）你只需要记住 3 条规则：1. **1 个抵押品 = 1 YES + 1 NO**2. **市场 = 状态机**（开放 / 锁定 / 已结算 / 取消）3. **ERC‑1155 管理多代币**（一个合约管所有市场）---# 二、Zui快搭建：直接复制即用合约```solidityhttps:// SPDX-License-Identifier: MITpragma solidity ^0.8.20;import "@openzeppelin/contracts/token/ERC1155/ERC1155.sol";import "@openzeppelin/contracts/security/ReentrancyGuard.sol";https:// 快速搭建：Polymarket 预测市场 代币状态管理（Zui简可用版）contract SimplePolymarketTokens is ERC1155, ReentrancyGuard { https:// 市场状态 enum Status { OPEN, https:// 可铸造/合并 LOCKED, https:// 停止交易 SETTLED, https:// 已结算 CANCELLED https:// 已取消 } https:// 市场结构 struct Market { uint256 yesId; uint256 noId; address collateral; Status status; bool result; https:// Zui终结果 } uint256 public marketCount; mapping(uint256 => Market) public markets; mapping(bytes32 => bool) public redeemed; event Created(uint256 marketId, uint256 yes, uint256 no); event Minted(uint256 marketId, address user, uint256 amount); event Merged(uint256 marketId, address user, uint256 amount); event Settled(uint256 marketId, bool result); event Redeemed(uint256 marketId, address user, uint256 amount); constructor() ERC1155("ipfs:https://QmXXX/{id}.json") {} https:// ========================================== https:// 1. 创建市场（自动生成 YES / NO 代币） https:// ========================================== function createMarket(address collateral) external returns (uint256) { uint256 id = ++marketCount; uint256 yesId = id * 10 + 1; uint256 noId = id * 10 + 2; markets[id] = Market({ yesId: yesId, noId: noId, collateral: collateral, status: Status.OPEN, result: false }); emit Created(id, yesId, noId); return id; } https:// ========================================== https:// 2. 铸造代币（抵押 → YES + NO） https:// ========================================== function mint(uint256 marketId, uint256 amount) external nonReentrant { Market storage m = markets[marketId]; require(m.status == Status.OPEN, "not open"); IERC20(m.collateral).transferFrom(msg.sender, address(this), amount); _mintBatch(msg.sender, _ids(m), _amounts(amount), ""); emit Minted(marketId, msg.sender, amount); } https:// ========================================== https:// 3. 合并代币（YES + NO → 退回抵押） https:// ========================================== function merge(uint256 marketId, uint256 amount) external nonReentrant { Market storage m = markets[marketId]; require(m.status == Status.OPEN, "not open"); _burnBatch(msg.sender, _ids(m), _amounts(amount)); IERC20(m.collateral).transfer(msg.sender, amount); emit Merged(marketId, msg.sender, amount); } https:// ========================================== https:// 4. 结算市场（预言机上报结果） https:// ========================================== function settle(uint256 marketId, bool result) external { Market storage m = markets[marketId]; require(m.status == Status.OPEN, "can settle only open"); m.status = Status.SETTLED; m.result = result; emit Settled(marketId, result); } https:// ========================================== https:// 5. 赎回奖金（用户兑奖） https:// ========================================== function redeem(uint256 marketId) external nonReentrant { Market storage m = markets[marketId]; require(m.status == Status.SETTLED, "not settled"); bytes32 key = keccak256(abi.encode(marketId, msg.sender)); require(!redeemed[key], "already claimed"); redeemed[key] = true; uint256 win = m.result ?
