I am building a social website and want each of my users to have a secure bitcoin, litecoin, ripple and fiat wallet. The site will have a store area to purchase goods. I will also be adding a auction type marketplace to the site. The following is what I'm looking for: Mnemonic password reset When user registers he gets unique mnemonic key that he will use in case he forgets password. Escrow When user purchase any item there is fee (for admin, can be set) and automated escrow. In case seller did not delivered goods or goods are not what they are supposed to be, buyer can open dispute. Both users and admin have access to dispute discussion Feedback There are two parts of this system. Feedback score and trust rating. Feedback score is basically percentage of positive feedback and Trust rating can be Very Low, Low, Average or High (Unproven if user has less then five feedbacks) Send coins between each user using escrow system whether on marketplace or social profile Make purchases with fiat using the escrow system Access to wallets from profile on social page and market page Full access to private keys of each wallet for the user Dispute button in marketplace and social profile Dispute to be settled by admin Crypto price posted for purchases must change as crypto prices change and say what it is equal to in USD Website is written in PHP, but you can integrate any language necessary as long as YOU can install and complete set up for working product.
