Globaldev Group is hiring Web3 Senior Fullstack Blockchain Developer

Desired Qualifications

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. GovernanceImplement 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.

Duties & Responsibilities

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.

Other

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
