# get\_chain\_information

获取 EVM 链基本信息。

## 方法定义

```python
def get_chain_information(self, show_timeslot: bool = True, show_client_version: bool = True) -> ChainInformationData
```

## 参数说明

| 参数                    | 类型   | 说明                            |
| --------------------- | ---- | ----------------------------- |
| show\_timeslot        | bool | 是否显示 timeslot,默认为 True        |
| show\_client\_version | bool | 是否显示 client\_version,默认为 True |

## 返回值

返回 ChainInformationData 对象,包含以下字段:

| 字段              | 类型             | 说明         |
| --------------- | -------------- | ---------- |
| chain\_id       | int            | 链 ID       |
| block\_number   | BlockNumber    | 当前区块高度     |
| gas\_price      | Wei            | Gas 价格     |
| timeslot        | Optional\[int] | 平均出块时间(可选) |
| client\_version | Optional\[str] | 客户端版本(可选)  |

## 示例代码

```python
# 获取所有信息
info = chain.get_chain_information()
print(f"Chain ID: {info.chain_id}")
print(f"Current Block: {info.block_number}")
print(f"Gas Price: {Web3.from_wei(info.gas_price, 'gwei')} Gwei")
if info.timeslot:
    print(f"Average Block Time: {info.timeslot}s")
if info.client_version:
    print(f"Client Version: {info.client_version}")

# 不显示 timeslot 和 client_version
info = chain.get_chain_information(show_timeslot=False, show_client_version=False)
```
