# PythResolver.sol

使用 Pyth 价格更新结算订单簿市场。

## 结算流程

1. 市场到期后，任何人都可以调用 `resolveMarket(...)` 提交 Pyth update data。
2. Resolver 从 `msg.value` 支付 Pyth update fee；多余 ETH/BNB 会退回。
3. Pyth 验证 update data，并返回市场配置 feed 在有效结算窗口内的价格。
4. 如果这是首次有效提交，市场进入 `Resolving`，并启动 90 秒 finality window。
5. 在 finality window 内，任何人都可以提交更早且会改变结果的有效 update。
6. finality 后，任何人都可以调用 `finalizeResolution(...)`；结果规则为 `price >= strike` → YES 胜出，`price < strike` → NO 胜出。

## 主要函数

```solidity
function resolveMarket(uint256 factoryMarketId, bytes[] calldata priceUpdateData)
    external
    payable

function finalizeResolution(uint256 factoryMarketId) external
```

`resolveMarket` 要求 `msg.value` 至少覆盖 `pyth.getUpdateFee(priceUpdateData)`。当前核心 CLOB 合约不支付 resolver bounty。

## 说明

* Price ID 以 `bytes32` 存在 `MarketFactory.marketMeta` 中。
* 结算是 permissionless 的，但通常由托管 keeper 执行。
* Confidence check 会拒绝价格不确定性过高的 update。
* 如果市场无法使用有效 Pyth data 结算，factory 可以进入配置的 fallback / cancellation 流程。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.strike.fun/zh/zhi-neng-he-yue/pyth-resolver.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
