Our team was asked to develop a secure crypto trading platform. It should allow making online deposits and withdrawals, exchanging fiat and cryptocurrencies, earning yield by utilizing staking and farming pools.
Solution
User interface
The platform is available as a web app and mobile app both for iOS and Android. This lets us cover a wider audience and provide a seamless user experience.
Deposit & Withdrawal
The functionality for making deposits and withdrawals was made easy to understand and quick to perform. The deposits can be made with bank transfers and crypto transfers. As for the withdrawal, the user can also use bank and wire transfers as well as move crypto to other exchanges and wallets.
Types of Accounts
The user can interact with the platform within a trade account and a high yield account. The trade account lets the user make a deposit with USD or crypto and earn by trading 4 available assets: Bitcoin, Ethereum, USDC and USDT. The high yield account requires only a deposit and lets the user earn yield passively by storing money on the platform.
Sign Up & ID Verification
Coinchange guarantees a secure sign up process, data encryption and safe storage of users’ funds. The user is required to complete Identity Verification to get full access to the platform features.
Business logic
Algorithms in the CoinChange platform allow the purchase or sale of cryptocurrency at a more favourable rate, by connecting to decentralized and centralized exchanges. Platform’s profit is earned by constantly generating new quantum models and bringing them to market.
Our team have created an infrastructure in which capital moves safely. From storage to the exchange, then to various blockchains and all the way back. The whole process is well-established, so in case of emergency all money is quickly transferred to secure storage and trading operations are shut down.
