"React Mining App: Implement LIVE Crypto Withdrawal via MetaMask Integration

We need a skilled React/Web3 developer to bridge the gap between our high-fidelity mining simulator and a fully functional withdrawal feature that processes a real transaction using a connected wallet.
The core mining logic is simulated, but the final, critical step—the payout—must interact with a live Web3 wallet (MetaMask) to initiate a real token transfer.


The Challenge & Goal

The provided code ([login to view URL]) currently uses a simulated handleWithdrawfunction that only updates the local state balance.
Your primary task is to overhaul the handleWithdraw function to initiate a real-world transaction via the connected wallet's provider (e.g., [login to view URL]).

Key Tasks

3. Wallet Interaction Upgrade: Modify the handleWithdraw function to utilize the Web3 provider (like MetaMask) retrieved in the existing connectWallet function.
5. Real Transaction Simulation: Instead of a setTimeout, you must implement the logic to:
* Construct a Transfer Transaction:Create a transaction object (to address, value/amount of WBTC/WETH, etc.).
* Call [login to view URL]:Use the eth_sendTransactionmethod to prompt the user's MetaMask/Web3 wallet to sign and broadcast the transfer of the simulated balance amount to their wallet address.
7. Advanced State Management: Update isWithdrawing and withdrawalStatusbased on real transaction life cycles:
* "Awaiting Wallet Confirmation"(User needs to approve in MetaMask)
* "Transaction Broadcasted/Pending"
* "Transaction Confirmed"
* "Transaction Failed (Revert/User Reject)"
9. Error Handling: Implement robust try...catch blocks to capture and log errors returned by the wallet/provider.
11. Balance Update: Only deduct the tokens from the local balance AFTER the transaction is confirmed on-chain (or simulated confirmed).


Tech Stack Requirements

* Frontend: React, [login to view URL], ShadCN/UI, Framer Motion
* Web3 Expertise (MUST HAVE): Deep familiarity with [login to view URL] or [login to view URL] (or direct [login to view URL] API calls) and handling wallet permissions (eth_requestAccounts) and transactions (eth_sendTransaction).
* Target Chain: The transactions should be built for the asset (WBTC/WETH) on a mainnet fork, the code must be secure.

Compensation & Urgency

This is an urgent task requiring a genuine Web3 integration expert.
Budget: $500 - $750 CAD Higher range reflects the requirement for secure, live crypto integration).
