feat: Add useEnsureCorrectChain hook for chain enforcement

[Adebesin-Cell]

Summary

This PR introduces a new React hook, useEnsureCorrectChain, designed to simplify and standardize the process of ensuring a connected wallet is on the correct blockchain network.

The hook provides a clear status state machine and utilities for prompting network switches, significantly improving developer experience when building dApps that require specific chain interactions.

✨ What’s Included

1. New Hook: useEnsureCorrectChain.

A dedicated hook that manages and enforces that the connected wallet is on a required chain.

2. Unified Status Flow

The hook exposes a deterministic status state machine:

idle → wrong-network → switching → correct

This makes it easier to:

• Drive UI states (banners, modals, disabled buttons)
• Avoid ad-hoc network checks across components
• Centralize chain validation logic

3. Programmatic Chain Switching

The hook provides:

• switchToCorrectChain() — Prompts the wallet to switch to the required network.
• dismiss() — Allows consumers to temporarily ignore the wrong-network state.

4. Status Change Callback

An optional onStatusChange callback enables reacting to transitions (e.g., open/close modals automatically).

Example use cases:

• Auto-open a “Wrong Network” modal
• Track analytics events on network switch
• Trigger side effects when switching completes

5. Documentation

Added comprehensive README documentation including:

• Basic usage example
• Callback integration example
• Full API reference

🎯 Why

Handling wallet network state is a common requirement across dApps. Previously, this logic had to be implemented manually in each feature or component.

This hook:

• Reduces duplicated logic
• Standardizes network enforcement patterns
• Improves UI consistency
• Simplifies onboarding for developers

🔄 Backwards Compatibility

No breaking changes.
This is a purely additive feature.

Summary of Changes

Hello @Adebesin-Cell, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new useEnsureCorrectChain React hook, designed to simplify and standardize the process of ensuring a user's connected wallet is on the correct blockchain network. It provides a clear state machine for network status and offers utilities for guiding users to switch networks, significantly improving the developer experience for building dApps that require specific chain interactions.

Highlights

• New Hook: useEnsureCorrectChain: Introduced a new React hook, useEnsureCorrectChain, to manage and enforce that the connected wallet is on a specific blockchain network.
• Unified Status Flow: The hook provides a clear, enumerated status flow (idle → wrong-network → switching → correct) to represent the wallet's chain state, simplifying UI logic.
• Programmatic Chain Switching: Includes a switchToCorrectChain function to programmatically prompt the user to switch to the required network, and a dismiss function to ignore the wrong-network state.
• Status Change Callback: An optional onStatusChange callback allows developers to react to status transitions, useful for opening or closing modals based on network state.
• Comprehensive Documentation: Added detailed documentation to the README.md covering basic usage, callback examples, and API reference for the new hook.

Code Review

This pull request introduces a new useEnsureCorrectChain hook, which is a great addition for ensuring users are on the correct network. The implementation is solid, but I've identified a few areas for improvement related to React hook best practices and error handling. My suggestions focus on memoizing functions and derived values with useCallback and useMemo for better performance and stability, and refining the error handling strategy to make the hook more robust and easier to consume without causing unhandled promise rejections.
