| -------------------------- | ----- |
| Optional\[List\[HexBytes]] | 存储值列表 |

## 示例代码

```python
# 获取前10个存储槽的值
storage_list = chain.dump_storage("0x...", 0, 10)
if storage_list:
    for i, value in enumerate(storage_list):
        print(f"Slot {i}: {value.hex()}")

# 获取指定范围的存储值
storage_list = chain.dump_storage("0x...", 100, 120)
if storage_list:
    for i, value in enumerate(storage_list, start=100):
        print(f"Slot {i}: {value.hex()}")
```
