FLEXIR

Flexir is a revolutionary platform tackling crypto liquidity challenges by enabling seamless trading of points, NFTs, and pre-market assets before the Token Generation Event (TGE). Using smart contracts, Flexir ensures real-time ownership transfer, offering users unparalleled liquidity and flexibility. With a user-centric approach, competitive transaction fees.

Join us in transforming the future of crypto markets.

Flexir was built using a combination of cutting-edge technologies to deliver a seamless, secure, and scalable platform for pre-TGE asset trading. Here are the key details of how the project was developed:

1. Frontend Development Technology Stack: Next.js, TypeScript, React, and Tailwind CSS. Features: User-friendly interface optimized for crypto traders with minimal friction. Wallet connection through MetaMask integration for seamless login and asset management. Real-time data updates using WebSocket for live trading and pricing information.
2. Backend Development Technology Stack: Node.js with Express and TypeScript. Architecture: REST APIs for handling transactions, user data, and integration with blockchain nodes. Database: MySQL for user profiles, transaction logs, and metadata storage. The schema was designed with efficiency and scalability in mind, especially for high-frequency trading scenarios.
3. Blockchain Integration Smart Contracts: Written in Solidity and deployed on EVM-compatible blockchains. Smart contracts enable secure ownership transfers of assets in real-time, ensuring trustless transactions. Key Contracts: PointMarket: Facilitates the listing and trading of pre-TGE points. USDT: Allows stablecoin transactions for ease of entry into the market. ORB Token: Native token for incentivizing platform activity. Deployed Network: Linea (EVM-compatible blockchain). The Linea network provides fast transactions and low gas fees, which are critical for frequent trading activity.
4. Partner Technologies Etherscan: For verifying and showcasing deployed smart contracts. MetaMask: For wallet integration, allowing easy access to the platform. Web3.js: Facilitates communication between the DApp and the blockchain.
5. Notable Hacks and Challenges Dynamic Smart Contract Updates: We implemented a mechanism to automatically update wallet addresses during resale transactions, ensuring seamless transfer of ownership. This required a unique event-driven architecture combining smart contracts and backend services. Gas Fee Optimization: Early versions had higher-than-expected gas fees. By streamlining smart contract functions and reducing redundant calls, we significantly lowered transaction costs. NFT and Point Market Integration: Merging NFT and point markets required a flexible architecture to handle multiple asset types while maintaining efficiency.
6. Development Tools and Practices Development Environment: A local setup using Hardhat for smart contract testing and MySQL for database simulation. Version Control: GitHub for source control and CI/CD pipelines for automated deployment to Linea. Monitoring: Custom dashboards for tracking transaction volumes and identifying performance bottlenecks in real time. This tech stack and approach allowed us to create a robust, user-friendly platform tailored for pre-TGE trading, with scalability and flexibility to expand into other markets in the future.
