# eth_getStorageAt | Base

Base API method `eth_getStorageAt` retrieves the value from a specific storage position of a contract at a given address. This method is useful for inspecting the state of smart contracts at specific points in their execution or at a particular block.

This example makes a call to slot 7 of the [USDC contract](https://basescan.org/address/0x833589fcd6edb6e08f4c7c32d4f71b54bda02913) on the Base Mainnet.

<Note>
  When called against a block older than the latest \~128 blocks, this method is treated as an archive request (2 RUs instead of 1 RU). See [request units](/docs/request-units#archive-state-methods).

## Parameters

* `address` — the address of the contract to access.
* `position` — the storage position to inspect, given as a hexadecimal value.
* `block` — the block number (in hexadecimal) or one of the strings `"earliest"`, `"latest"`, or `"pending"`, indicating the state to consider. The default is `"latest"`.

## Response

* `result` — the value from the specified storage position at the given address, returned as a hexadecimal string.

## Use case

The `eth_getStorageAt` method is essential for:

* Developers and auditors who need to verify the state and behavior of smart contracts by inspecting their storage.
* DApps that require access to contract state that is not exposed through contract methods.
* Tools and services that monitor contract state for changes, updates, or anomalies.
