Fix the issue with slow response time after submitting a transaction

## Overview
After submitting a transaction through Smart Wallet, the app sometimes takes a long time to respond, making users unsure if the transaction went through.

## Problem Description
- Users experience slow response times after submitting a transaction.
- The app does not provide immediate feedback, leaving users unsure if the action was successful.
- This could cause confusion and frustration for users, especially when they’re unsure whether to retry or wait.

## Expected Behavior
- The app should provide instant feedback once a transaction is submitted.
- Users should see a confirmation that the transaction was successfully initiated without long delays.

## Proposed Solution
- Improve the response time after submitting transactions.
- Show a clear confirmation message or animation indicating the transaction is being processed.

No files, tests, or entry points are named. Start by tracing the Smart Wallet transaction-submission flow, then verify that submission gives immediate confirmation or processing feedback without requiring users to wait or retry.
