Project description:
"I am looking for an experienced Web3 developer to debug and complete a token withdrawal function within an existing React component.

The application is a dashboard for a (simulated) crypto-mining platform called FreeFlowAIBoostEducational. Users accumulate a balance of WBTC or WETH (this balance is currently tracked in the component's React state) and need to be able to withdraw it.

The Current Problem:

The handleWithdraw function is already partially implemented but is not working correctly. It successfully connects to the user's MetaMask wallet, gets the signer, and instantiates an [login to view URL] ERC-20 token contract. However, the final step—executing the [login to view URL]() transaction—is either not implemented correctly or failing.

Key Requirements & Logic Flow:

A critical part of this project is understanding the existing confirmation flow. The withdrawal process is tied to a separate function (handleConfirm) which:

Presents a Bootstrap modal to the user.

Prompts the user to enter their "private key or seed phrase."

Sends this key to a backend server ([login to view URL]) for validation.

Sets a confirmed flag in the React state if successful.

Your task is to make the handleWithdraw function work within this existing system. The [login to view URL]() call must only be executed after the confirmed state variable is set to true.

Your Responsibilities:

Analyze the provided [login to view URL] React component.

Diagnose and fix the bug in the handleWithdraw function.

Correctly implement the [login to view URL] [login to view URL]() logic so that it successfully initiates a transaction when the user clicks "Withdraw."

Ensure the entire flow is functional: Connect Wallet -> Mine -> Click Withdraw -> Confirm in Modal -> Transaction is Sent.

Required Skills:

React: Strong experience with React Hooks (useState, useEffect).

[login to view URL]: Expertise in connecting to wallets, instantiating contracts, and sending ERC-20 token transactions.

Web3 Integration: Deep understanding of MetaMask, signers, and providers.

JavaScript (ES6+): Asynchronous programming (async/await).

Bootstrap: Familiarity with Bootstrap modals is a plus (for working with the existing confirmation modal).

To Apply:

Please send a brief explanation of how you would approach debugging and fixing the handleWithdraw function based on the description above. Include examples of previous projects where you've worked with [login to view URL] and ERC-20 token transfers." (client-provided description)
