Cryptocurrency Pairs
The ARBchange web app makes it possible for buyers and sellers to exchange ETH/ECOIN, OMG/ETH, OMG/ECOIN, ETSH/ECOIN, and OMGSH/ECOIN. ERC20 Token Standard provides infinite liquidity and automatically facilitates price determination.
| Blockchain technology and the growth of a new asset class dictate their own terms. As a result, the demand for exchanges specializing exclusively in digital currencies is growing steadily. Competition is huge. To stand out from the existing trading platforms, business owners must implement some specific solutions to make their platform number one for the buyer and sellers. Our clients hired us to create a crypto-exchange in Blockchain with unique features through which buyers and sellers will profitably trade without third party participation. |
Challenge
To meet our clients' needs, our challenge was to develop a safe and convenient platform with real-time features and the USP so that users could:
- сompare current cryptocurrency prices with other exchanges and choose the most profitable one to buy/sell tokens
- predict the ETH price (the price will be lower or higher) in order to predict the ETSH price and buy/sell at the best price
