+Retrieves the `max_fee` of the proof with the highest nonce in the batcher queue for a given address.
+
+This value represents the maximum fee limit that can be used when submitting the next proof. To increase the fee limit for a new proof, you must first bump the fee of the previous proofs queued in the batcher.

+```rust
+pub async fn get_last_max_fee(
+    network: Network,
+    address: Address,
+) -> Result<U256, GetLastMaxFeeError>
+```
+
+#### Arguments
+
+- `network` - The network from which to retrieve the last `max_fee`.
+- `address` - The user address whose last `max_fee` will be retrieved.
+
+#### Returns
+
+- `Result<U256, GetLastMaxFeeError>` - The `max_fee` of the proof with the highest nonce for the given user, or `U256::MAX` if the user has no proofs in the queue.
+
+#### Errors
+
+- `ConnectionFailed` if there is an error connecting to the batcher.
+- `ProtocolMismatch` if the protocol version doesn't match.
+- `SerializationError` if there is an error serializing/deserializing the message.
+- `InvalidRequest` if the request is invalid.
+- `UnexpectedResponse` if the batcher responds with an unexpected message.
+- `GenericError` if the error doesn't match any of the previous ones.
+
+#### Notes
+
+- Returns `U256::MAX` (2^256 - 1) when no proofs are present in the queue for the user.
+
 ### `get_chain_id`
 
 Returns the chain ID for a given rpc url.

+### **get-user-last-max-fee**
+
+#### Description:
+
+Retrieves the `max_fee` of the proof with the highest nonce in the batcher queue for a given address.
+
+This value represents the maximum fee limit that can be used when submitting the next proof. To increase the fee limit for a new proof, you must first bump the fee of the previous proofs queued in the batcher.

+
+#### Command:
+
+`get-user-last-max-fee [OPTIONS] <user_ethereum_address>`
+
+#### Options:
+
+- `<user_ethereum_address>`: User's Ethereum address.
+- One of the following, to specify which Network to interact with:
+  - `--network <working_network_name>`: Network name to interact with.  
+    - Default: `devnet`  
+    - Possible values: `devnet`, `holesky`, `mainnet`, `hoodi`
+  - For a custom Network, you must specify the following parameters:
+    - `--aligned_service_manager <aligned_service_manager_contract_address>`
+    - `--batcher_payment_service <batcher_payment_service_contract_address>`
+    - `--batcher_url <batcher_websocket_url>`
+
+#### Example:
+
+```bash
+aligned get-user-last-max-fee \
+<USER_ETH_ADDRESS> \
+--network holesky
+```
+
+#### Notes:
+
+- Returns `U256::MAX` (2^256 - 1) when no proofs are present in the queue for the user.
