Project Requirements for Blockchain DEX Platform.

Project Overview

  • Objective: To develop a decentralized exchange platform that enables users to trade cryptocurrencies with features similar to the following (https://purpleswap.me, https://intuitionexchange.com)
  • Target Technologies: React, Node.js/TypeScript, Web3.js, Solidity, Rust, Golang.
  • Supported Blockchains: Ethereum, Polygon, Binance Smart Chain (BSC).

Functional Requirements

  • User Management
  • User registration and authentication via crypto wallets (MetaMask, WalletConnect, etc.).
  • Profile management with wallet address display and transaction history.

Trading Features

  • Market and limit order functionalities.
  • Ability to place and cancel trades.
  • Real-time order book updates.
  • Support for various trading pairs across Ethereum, Polygon, and BSC.

Liquidity and Staking

  • Liquidity pool creation and management.
  • Staking options for users to earn rewards.

Token Support

  • Integration with ERC20 tokens and other standards relevant to Polygon and BSC.
  • Token listing feature for new tokens based on user requests or governance proposals
  • Analytics Dashboard
  • Real-time market data analytics (price charts, volume, liquidity).
  • User trading performance metrics and profit/loss summary.

Governance

  • Implement decentralized governance features allowing token holders to propose and vote on platform improvements.

Technical Requirements

Frontend Development

  • Build the UI using React.js and ensure the interface is responsive and user-friendly.
  • Integrate Web3.js for blockchain interactions.

Backend Development

  • Use Node.js/TypeScript for server-side development.
  • Implement a RESTful API to manage trades, user data, and liquidity pools.
  • Ensure secure storage and handling of user data.
  • - Smart Contract
  • Develop Solidity smart contracts for key functionalities (trading, liquidity pools, governance).
  • If using Rust, ensure compatibility with the targeted blockchain.
  • Use Golang for any microservices or backend services that require performance optimization (e.g., handling transactions).
  • - Blockchain Integration
  • Use Ethereum for primary transactions and smart contracts.
  • Implement bridging with Polygon and Binance Smart Chain to allow cross-chain trading.
  • Leverage decentralized oracles (e.g., Chainlink) for real-time data feeds.

Security Requirements

  • Conduct smart contract audits to ensure security against vulnerabilities (e.g., reentrancy, overflow).
  • Implement secure wallet interactions and user authentication methods.
  • Regularly update dependencies and apply security patches.

Performance Requirements

  • Ensure low latency for transaction processing and user interactions.
  • Optimize the platform to handle a significant number of concurrent users and transactions.

Testing Requirements

  • Test smart contracts using frameworks like Hardhat or Truffle.
  • Frontend and backend unit testing and integration testing.
  • Conduct performance testing to assess the scalability of the platform.

Deployment Requirements

  • Deploy smart contracts on Ethereum, Polygon, and BSC.
  • Set up CI/CD pipeline for deploying frontend and backend applications.
  • Use decentralized storage solutions for storing off-chain data if needed (e.g., IPFS).

Documentation Requirements

  • Technical documentation for developers about the codebase and architecture.
  • User documentation providing instructions on using the DEX platform.
  • API documentation for any public APIs provided

Interview stages:

  • Screening call with a recruiter
  • Test task
  • Tech call with client
