Hi, Looking for a software developer or team who will be able to develop the frontend and backend development and create a similar platform like [login to view URL] or www.paxful.com. It is a P2P marketplace for Bitcoin. The platform is a P2P (person 2 person marketplace bitcoin for money platform) it is where people meet in person and exchange bitcoin for money or money for bitcoin in person. We want to give working people a simple, fair and secure platform for trading among each other. Here is what needs to be done · Bitcoin web wallet. Important parts are: generate bitcoin addresses for users, send out payments, receive payments and confirm transaction after n confirmations. All at the same time properly handle users balances. · Create offers/ads. When you have basic flow of users bitcoin wallets in hand, it's time to move into marketplace part. First part is the offer creation. What are the rules here like hard-coded payment methods (we went step further and allow users to dynamically create new payment methods), payment window time, BTC price margin, offer visiblity to users? etc etc... Additionally have all the CRUD (create,read,update,delete) operations for the offer and all the business logic like updating price every 10 minutes, activation, deactivation etc... · Now comes the trading part - start trade, mark trade as paid, complete trade, auto-cancel trade, cancel trade by user, dispute trade, leave feedback. For all these trade actions the business logic has to be extremely well thought through and code written well with all edge cases taken into account. Otherwise you can end up with adding balance twice, deleting accidently records or simply break database schema. · Trade live chat - Not a small part, considering that you need file upload here, moderator messages in case of dispute and anything else you see there. · Feedback system is another part. Would you make it different? How complex would that be then? We have different feedback approach - feedback can be left for every completed trade and also a reply can be left. In case dispute a loser can't leave feedback. · Reporting capabilities for any historical data/actions - users completed trades, activity ledger, transactions ledger, generated bitcoin addresses and any other historical data you need to output. · Backend admin for website health - bitcoin balance in bitcoin cores, users balances, active trades, history, anything you can think of you want to see in real time. All these above points are only specifically about bitcoin peer to peer marketplace. I'm not mentioning anything about proper enterprise software plus secure website development - unit tests, replication, disaster recovery, build automation, backups, validations, protection against all kinds of website attacks and so on.

Hi there, I have read everything and according to my understanding, you are looking to create an exchange for crypto currencies. There will also be option for the feedbacks, chats, reporting system, and the complete order and wallet management. The site will also have admin panel for all the managements. Here are my questions: - Do you want to create the exchange only for the bitcoin or also want to have other cryptocurrencies as well? - Can you please let us know which payment systems would you like to add in the system? Just so you know I am flexible in prices, as quality & long-term relationship is more important. Look forward to hearing from you. Regards, YK LEADconcept

THE BAD: I want to apologize for putting in the price that I did, we have been down this path and are aware of all the little hidden costs, resources and time needed for a successful completion of a project of this nature. In this project you will have 8-9 team members (that includes one PM - ours is German we do not allot other nationalities to be PM on Westerners due to language barriers- sounds harsh but its effective). What makes your project a tad bit unique and challenging is allot of what you want has to be done custom to your liking as there is not to many 3rd party software (yet) available for CrypoCurrency. THE GOOD: Options such as address/wallet generation is readily available and very little resources and development is needed same goes for the Chat and Add parts- these parts you can use free open source software where all we have to do is just tie it into your system. The Reporting capabilities for any historical data/actions as well as the Backend admin for website health is basically a mirror of the first 2 ...in a way they will depict how the back end will be developed (the most important part). I can rite a book on how to approach your project with a step by step guide, typically I opt to meet with you in person or you come to our office and work with us as that really ensures smooth sailing. We have many client within your range that we have delivered litteraly in time or 1-2 weeks behind (which is the holly grail in Software) who I can (ran out of space
