TrustLayer OPN
What We Built
TrustLayer OPN is a decentralized trust and reputation protocol built on OPN Chain.
The protocol creates an on-chain trust score for wallet addresses based on verifiable activity and transaction history. Users, DeFi applications, and future lending protocols can use these scores to assess credibility and reliability without relying on centralized reputation systems.
TrustLayer aims to become the trust infrastructure layer for Open Finance on OPN Chain.
Problem
One of the biggest challenges in decentralized finance is the lack of transparent trust mechanisms.
Wallet addresses are anonymous, making it difficult to evaluate whether a user has a history of reliable interactions. New users, lenders, and DeFi protocols often have no way to measure credibility before engaging in transactions.
This creates risk and limits the growth of decentralized financial systems.
Solution
TrustLayer OPN introduces a transparent and decentralized reputation framework.
The protocol records wallet activity and generates trust metrics that can be used across multiple applications.
All reputation data is stored on-chain, ensuring transparency, verifiability, and resistance to manipulation.
Key Features
- On-chain wallet reputation profiles
- Dynamic trust score generation
- Transaction history tracking
- Transparent reputation storage
- Public profile lookup
- Open infrastructure for future DeFi integrations
- Fully deployed on OPN Chain
How It Works
- A wallet interacts with applications built on OPN Chain.
- Transaction activity is recorded through the TrustLayer smart contract.
- The protocol updates the user's reputation profile.
- A trust score is calculated based on transaction history and activity.
- Other applications can use these scores to evaluate wallet credibility.
Smart Contract
The TrustLayerRegistry contract stores:
- Trust scores
- Transaction counts
- Total transaction volume
- User reputation profiles
All data is publicly accessible and verifiable on-chain.
Why OPN Chain
OPN Chain provides a fast and low-cost environment for building decentralized financial infrastructure.
TrustLayer leverages OPN's scalability to create a foundational trust layer that can support future lending, reputation, and risk assessment systems.
Future Vision
Phase 1
- Core reputation registry
- Trust score calculation
- Wallet profile management
Phase 2
- Reputation badges and achievements
- Historical trust tracking

Impact
