Hi, We are very experienced creating web2 and nft marketplace apps. But for topics above we have not experience yet. The app will work like this: A user goes to an exchange office, deposit USD. In the system, user can purchase coins listed below and then, those purchased coins will be transferred to his/her wallet/wallets. Users has to view real time coin prices without a lag. Users pick a coin (for now some specified coins will be used, listed below). User selects a coin and buy/sell/withdraw. In this process users will view and use our app but at the same time they will be connected to a CEX in order to purchase crytpo coins. There will be only one price for each coin. After that we will add some commission (like 1%, the commissions will be holded in a specified cold wallet). Then transfer will be done. Users can also transfer coins with each other as well. So we want you to integrate multichain wallets (not a 3rd party wallet like metamask) and create a CEX which will be do transactions processes. Network will be BEP20 For now those are our requirements. So please look for them and tell us a time and a price of total. We want you to do this in a short time. Thank you. - Coins will be listed (Might be change): - BTC - ADA - LINK - DOT - LTC - BNB - USDT - ETH Some key topics: - It will be token like USDT, we are not going to use payment methods like Paypal. - bep20 is going to used as a network. - There will be no third party wallet app like Metamask. We want you to integrate multichain wallets. - About importing USD is will be like this: We will have a pool (wallets) and we take the money from customers and we will transfer to their account. In generally what you will be responsible for: - Multichain wallet integration - CEX - Those will be connected to a React project. - Backend built with Nodejs, PostgreSQL
