Overview
A decentralized blockchain project faced increasing challenges as its metaverse and NFT marketplace grew in popularity: Swap, Bridge, Torch, Liquidity Pools and Rewards.
The platform’s initial architecture was not designed to support high user activity, leading to performance bottlenecks, frequent transaction errors, and difficulties in managing digital assets. Additionally, the marketplace relied on multiple microservices that suffered from instability and security vulnerabilities.
To address these issues and ensure a seamless user experience, the company sought expert assistance in auditing and modernizing its platform. The development team was tasked with conducting a full code audit, stabilizing microservices, rewriting the backend, and optimizing asset transactions. The ultimate goal was to enhance the platform’s scalability, improve security measures, and refine smart contract interactions for better transaction efficiency.
Challenge
The project faced several key challenges:
DAO, Ecosystem, Defi, Swap, Liquidity, Yield farming, Play to Earn, Web3 games, NFTs Buy and Sell and much more!
- Updating the NFT Marketplace: A major overhaul was required to enhance the marketplace’s functionality, improve UI/UX, and introduce new features to support digital asset transactions.
- Fixing Critical Bugs in Microservices: The platform was built on multiple interconnected microservices handling authentication, asset management, transaction processing, and analytics. Stability improvements were necessary to ensure seamless operation and data consistency.
- Code Auditing and Security Enhancements: A full security audit was needed to identify vulnerabilities, improve smart contract security, and strengthen data protection mechanisms before rewriting the marketplace backend.
- Scalability and Performance Optimization: The existing infrastructure was unable to handle increased traffic and transaction volumes, requiring significant improvements in backend performance and database optimization.
- Global Team Coordination: Development teams across different regions had to collaborate efficiently, overcoming communication barriers and aligning their workflows.
Solution
The team executed a structured modernization plan:
- Complete Backend Rewrite: Migrated the backend from its initial version to a newly optimized architecture using Node.js and Nest.js, significantly improving system performance, maintainability, and transaction processing speed.
- User Interface Enhancements: Implemented React, Next.js, and Tailwind CSS to create a more responsive and user-friendly experience, with improved navigation and streamlined asset management features.
- Microservice Stability Improvements: Fixed bugs across five essential microservices, ensuring secure authentication, asset ownership verification, and accurate transaction history tracking.
- Security Strengthening: Integrated advanced authentication mechanisms, encrypted asset storage, and improved smart contract validation protocols to prevent unauthorized transactions and ensure data integrity.
- Infrastructure Optimization: Upgraded the system’s scalability by leveraging cloud-based deployment solutions, database sharding techniques, and load-balancing strategies.
- Testing and Documentation: Conducted rigorous QA testing, including smart contract audits, and updated system documentation to facilitate future development and maintenance.
