Project Description: We are the owners of a token named MFC, and we are currently in the process of creating a website. Our requirement is to allow users to connect their wallets on this website and purchase MFC tokens from us. The process should be as follows: • The user connects their wallet and chooses the amount of MFC they want to purchase. • Upon confirmation, the equivalent amount of ETH should be deducted from the user’s wallet and transferred to our registered wallet in the system. • Simultaneously, the purchased amount of MFC should be transferred from our wallet to the user’s wallet. • The transaction completes once both transfers are successfully executed. The task at hand includes writing the smart contract, integrating it with the website (which is under development), and testing to ensure it works securely and as expected. Applicants should have experience in: • Smart contract development, particularly on the Ethereum network • Solidity programming language • Integration of smart contracts with web interfaces • Extensive testing and auditing of smart contracts for security vulnerabilities Note: The website’s development is outside the scope of this project. We are specifically looking for help with the smart contract creation and its integration. Please respond with: • Your estimated timeline for the completion of this project • Your cost estimate • Past projects of similar nature that you have completed We look forward to hearing from you.

To gain your trust, I can work with you for a while so that you can check my credentials. If you are happy with my work, we can move forward with the project. Questions: 1. Could you provide more information about your token "MFC"? Is it an ERC-20 token or based on a different standard? 2. What are the key functionalities you want to be implemented within the smart contract, apart from the token purchase process? Could you offer me a chance to collaborate with you? Let's speak as soon as possible.I'm eager to hear from you. Regards
