Hi, I am building the Metaverse Platform We need developer that can make Smart contract on eth / bnb / polygon That will allow user withdrawal custom coins From site with wallet connect (from his account) And add extra fee on withdrawal in base network coin The Flow is like this : 1. User login and play a game. 2. If user win he have positive balance in costume erc-20 token (can be new that you created) 3. User can connect with wallet connect (All wallets like here : [login to view URL] ) to the site and ask for withdraw 4. On the transaction we want to add small extra fee on top of the network fee: for example, in BNB network cost 1$ for this type of transaction we want to add 5$ extra fee in total its will 6$ in BNB coin 5. User approve the transaction - Our wallet gets 5$ and user get the costume erc-20 token instantly 6.

Dear Client, I bring over 7 years of experience as a seasoned full-stack developer, and I am interested to propose my expertise for the creation of a Metaverse Platform. The envisioned platform will incorporate smart contracts on Ethereum, Binance Smart Chain (BSC), and Polygon, enabling users to withdraw custom coins seamlessly through WalletConnect. The proposed flow involves users playing a game, accumulating a positive balance in a custom ERC-20 token upon winning. Users can then connect their wallets, like those supported on Dextools, and initiate withdrawals. To enhance this process, we plan to implement a small extra fee on top of the network fee, ensuring a smooth transaction experience. By approving the transaction, users instantly receive their custom ERC-20 tokens, while our wallet gains the extra fee. The backend will efficiently deduct the sum from the user's account in the database, ensuring a streamlined and secure process. Sincerely, Nadeem
