+   ```
+   TODO
+   ```
+   
+4. Once the calldata and the proposed upgrade are validated, you can create the upgrade transaction on [Safe](https://app.safe.global/home)
+
+5. Click on `New transaction` -> `Transaction Builder`

+7. Get the `ProxyAdmin` address, and paste it on `Enter Address or ENS Name`
+
+   To get the `ProxyAdmin` address the following command will copy the address to the clipboard:
+
+    ```bash
+    # SEPOLIA

+   
+   >    [!NOTE]

+
+8. If the ABI is not automatically filled, get the ABI and paste it on the corresponding box:
+
+    ```bash
+    jq ".abi" contracts/out/ProxyAdmin.sol/ProxyAdmin.json | pbcopy
