Describe the scope of work in detail. Please include a summary of key deliverables.
5Hz was engaged to expand our DeFi platform with two critical features: an AMM-based liquidity pool system and a staking/rewards module. The project spanned 9 months and involved both smart contract development and backend infrastructure. Phase 1 - AMM Liquidity Pool Development: 5Hz developed a complete automated market maker solution allowing users to provide liquidity, execute token swaps, and earn trading fees. This included implementing the constant product formula (x*y=k), slippage protection, and liquidity provider (LP) token minting/burning mechanisms. They integrated price oracle feeds to ensure accurate pricing and prevent manipulation. Phase 2 - Staking & Rewards Module: They built a staking system where users can lock tokens to earn rewards. This included implementing time-locked staking periods, reward calculation algorithms based on staking duration and pool size, automated reward distribution, and early withdrawal penalty mechanisms. Phase 3 - Backend Infrastructure: 5Hz architected a microservices-based backend to support these features, including transaction processing services, blockchain event indexers, and real-time data aggregation. They developed RESTful APIs and WebSocket endpoints for frontend integration, ensuring low-latency user interactions. Key Deliverables: Smart contracts for AMM liquidity pools (swap, add/remove liquidity functions) Smart contracts for staking mechanisms and reward distribution Comprehensive smart contract test suite with 95%+ code coverage RESTful API with 15+ endpoints for pool and staking operations WebSocket service for real-time liquidity and price updates Microservices for transaction processing and blockchain event indexing Database schema and data models for user positions and historical data Technical documentation and API documentation Deployment scripts and CI/CD pipeline configurationSecurity audit preparation documentation"
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
800+ users actively providing liquidity within the first 60 days of launch
Smart contracts processing 300-500 transactions daily with 99.8% uptime
Average transaction confirmation time of 15 seconds
Zero critical security vulnerabilities found in external audit
Reduced gas costs by 25% through optimized smart contract design
Delivered all features within the agreed timeline
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Overall, 5Hz demonstrated strong project management capabilities, though we experienced some initial challenges that are common in complex blockchain projects.
5Hz assigned a dedicated project manager who provided weekly progress updates and maintained open communication channels. At the project's outset, we had some difficulty aligning on the technical approach for the AMM implementation. Our internal team preferred one architectural pattern while 5Hz advocated for a different solution based on their experience. It took 2-3 weeks of discussions and technical evaluations before we reached a consensus. While this extended the kickoff phase, the collaborative debate ultimately led to a better solution that incorporated both perspectives. Most milestones were delivered on time, though we experienced occasional delays, typically 3-5 days. the best part was when we requested changes to the staking reward calculation logic mid-project based on community feedback, 5Hz adapted quickly and incorporated the changes without significant pushback.
What was your primary form of communication with 5Hz?
Virtual Meeting
Email or Messaging App
What did you find most impressive or unique about this company?
Their deep DeFi expertise and flexibility. 5Hz developers brought real-world protocol knowledge that improved our original design, and when requirements changed mid-project, they adapted seamlessly.
Are there any areas for improvement or something 5Hz could have done differently?
The initial planning phase could have been smoother. It would have been helpful if 5Hz had conducted a more thorough discovery session upfront to fully understand our existing architecture and technical preferences before proposing their approach. This would have shortened the 2-3 week alignment period we experienced at the start.
Additionally, while their communication was generally good, there were a few instances where we only learned about minor delays or blockers during our scheduled check-ins rather than proactively. Earlier heads-up on potential issues—even small ones—would have helped us adjust our internal planning.
