We need to develop a Multi-cryptocurrency wallet back-end and infrastructure

€5000-10000 EUR

Posted over 6 years ago

€5000-10000 EUR

Paid on delivery
Our wallet will be a multi-cryptocurrency wallet which is able to send and receive currencies, and convert them using ShapeShift integration which will avoid us from developing our proper exchange (for the time being) and which will also eliminate the issue of having the collaboration with several different exchanges. The conversion of the multi-crypto currency will happen in two stages, first stage would be that the crypto currency that is held by the owner (BTC, LTC, ETH …etc) will be converted into our own crypto coin and the second conversion will be from our crypto coin into the desired fiat currency (usd, euro, etc…) please only respond if you have relevant experience using blockchain technology and crypto currency
