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 original platform design failed to handle intense user activity which resulted in performance problems while processing transactions and managing digital assets became increasingly challenging. The marketplace depended on various microservices which experienced instability along with security vulnerabilities.
The company hired experts to audit and modernize its platform to fix these issues and deliver a smooth user experience. The development team received instructions to perform a complete code audit while stabilizing microservices and rewriting backend systems in addition to optimizing asset transaction processes. The primary objective involved scaling the platform while strengthening security defenses and optimizing smart contract performance to achieve superior transaction efficiency.
Challenge
The project faced several key challenges:
The project encountered challenges related to DAOs, Ecosystem development, Defi solutions, Swap platforms, Liquidity management, Yield farming techniques, Play to Earn models, Web3 games functionality and NFTs marketplaces.
- Updating the NFT Marketplace: The marketplace needed extensive redevelopment to boost its functions while refining UI/UX and adding features for digital asset transactions;
- Fixing Critical Bugs in Microservices: The platform’s architecture consisted of interconnected microservices that managed authentication functions as well as asset management operations along with transaction processing capabilities and analytics features. Stability enhancements were essential to maintain uninterrupted operations and secure data consistency;
- Code Auditing and Security Enhancements: Before the marketplace backend rewrite it was essential to perform a complete security audit to find vulnerabilities and enhance smart contract security and data protection measures;
- Scalability and Performance Optimization: The current system infrastructure proved insufficient for managing higher traffic and transaction volumes needing substantial backend performance enhancements and database optimization;
- Global Team Coordination: Development teams from various regions needed to achieve efficient collaboration by bridging communication gaps and synchronizing their workflows.
Solution
The team executed a structured modernization plan:
- Complete Backend Rewrite: The team transitioned the backend from its original version to a new and optimized structure based on Node.js and Nest.js which resulted in substantial enhancements to system performance and maintainability while also speeding up transaction processing;
- User Interface Enhancements: The team used React, Next.js, and Tailwind CSS to build a responsive user interface that enables smoother navigation and better asset management;
- Microservice Stability Improvements: The team resolved issues within five vital microservices to achieve secure authentication methods while maintaining asset ownership verification accuracy and reliable transaction history tracking;
- Security Strengthening: The system now incorporates sophisticated authentication tools paired with encrypted data storage and upgraded smart contract checks to stop unauthorized actions and maintain data accuracy;
- Infrastructure Optimization: The system’s scalability was enhanced by employing cloud-based deployment solutions together with database sharding techniques and load-balancing strategies;
- Testing and Documentation: We performed comprehensive QA testing with smart contract audits and revised the system documentation to enable future development and maintenance.
Tech Stack
- Front-End: JavaScript, React, Next.js, Tailwind CSS, StoryBook;
- Back-End: Node.js, Nest.js;
- Infrastructure & Security: Secure authentication, optimized asset management, cloud-based deployment, smart contract security enhancements;
- Blockchain: Ethereum, Web3.js, Solidity, Ethers.js, EVM.
Outcome
- Successful Code Audit: Implemented comprehensive security and performance audits to build a stable development foundation while maintaining blockchain security compliance standards;
- Enhanced NFT Marketplace: The platform received enhancements through a backend rewrite which led to better transaction processing capabilities as well as improved digital asset verification and user experience;
- Microservice Optimization: Troubleshooting key microservices fixed platform reliability issues while reducing transaction errors and maintaining seamless blockchain integration;
- Scalability & Performance Gains: Efficient database query optimization together with faster API response times and effective caching mechanisms enabled the platform to handle increased transaction loads.
