OverviewThe world of Web3 is rapidly expanding, with thousands of decentralized applications (dApps) emerging across various sectors like DeFi, NFTs, and DAOs. However, one of the biggest challenges users face is trust—how do they know which dApps are reliable, secure, and worth their time and investment?

Many users struggle with finding trustworthy reviews, identifying scams, and understanding dApp credibility. Unlike Web2 platforms such as Trustpilot or the App Store, Web3 lacks a structured verified review and rating system to guide users. This is where Certified App comes in. Certified App is a decentralized review and certification platform for Web3 applications, ensuring transparency, trust, and user safety through on-chain verification.



The Challenge
The challenge was to redefine and improve trust in Web3 applications by creating a transparent and user-friendly review system that prevents fake ratings, enhances credibility, and empowers users to make informed decisions. With Certified App, the goal was to provide an intuitive solution that enables users to discover high-quality, verified dApps while preventing misinformation and fraud.


The Process To design a solution that truly addresses the trust gap in Web3, we used the Design Thinking framework:
  1. Empathize – Understanding users’ needs and pain points.
  2. Define – Framing the problem statement and identifying core challenges.
  3. Ideate – Brainstorming and generating innovative solutions.
  4. Prototype – Designing and testing high-fidelity prototypes.
  5. Test – Gathering user feedback and iterating on improvements.


Empathize – Understanding Users & Their Problems
User Pain Points in Web3
  • Lack of trusted ratings for Web3 apps → Users struggle to determine which dApps are safe and reliable.
  • Unverified reviews and misleading information → Many platforms suffer from fake or manipulated ratings.
  • Overwhelming number of Web3 applications → Hard to discover quality apps without extensive research.
  • High entry barriers for newcomers → Many users don’t know where to start or which projects to trust.





Key Insight — Web3 users seek trust mechanisms similar to Web2 platforms like Trustpilot, App Store, and Google Reviews.


Competitor Research
We analyzed major platforms to understand existing solutions and gaps:
  • DappRadar – Aggregates dApps but lacks verified user-driven reviews.
  • DefiLlama – Provides DeFi analytics but doesn’t focus on user trust.
  • CertiK Skynet – Focuses on security audits rather than user experience.

Certified App differentiates itself with on-chain verified reviews, social trust indicators, and a certification system for Web3 applications.


Define – Framing the Problem Statement"Web3 users struggle to find trustworthy and high-quality decentralized applications due to a lack of transparent and verified rating systems, resulting in low trust and slower adoption of Web3 technologies."


User ArchetypeUnderstanding our target audience helps us design features that address their needs:
The Explorer – Actively seeks new Web3 apps and cutting-edge projects.
The Skeptic – Hesitant about Web3, needs strong social proof and security assurances.
The Newcomer – Just entering Web3, looking for guidance and safe recommendations.
The Investor – Evaluates dApps based on credibility and long-term potential.


Ideate – Finding Solutions

After gathering research insights, we brainstormed possible solutions. Some How Might We (HMW) questions:
  1. How might we prevent fake reviews and ensure transparency?
  2. How might we simplify dApp discovery for new users?
  3. How might we provide developers with a way to showcase credibility?

Crafting the Solution
  • On-chain Verified Ratings – Eliminates fake reviews through blockchain validation.
  • Trust Widget for dApps – Enables projects to display credibility on their platforms.
  • Social & Expert Proof – Displays reviews from verified users and industry experts.
  • Integrated Wallet Discovery – Recommends dApps within users' existing wallets.
  • Gamified Reputation System – Users earn credibility scores based on activity and trustworthiness.
