The impact of our project can be quantified and assessed using a combination of technical, economic, and user satisfaction metrics. 

1. Technical Metrics:
   - Pricing Accuracy: We can measure the accuracy of our real-time pricing models against actual market gas prices over a given period. This ensures the credibility of our derivative products.
   - Service Uptime: Ensuring that our platform has a high availability and reliability rate is crucial.

2. Economic and Business Metrics:
   - Adoption of Derivatives: Tracking the number of users purchasing and leveraging our gas price-based services.
   - Transaction Volume: The volume of gas fee transactions processed through our platform, indicating users' trust and adoption.
   - Cost Savings: A comparison metric showing the cost difference for users before and after using our services, illustrating financial benefits.

3. User Engagement and Satisfaction:
   - Onboarding Rate: The rate at which new users are adopting our platform and its services, which indicates the market’s reception and trust in our solution.
   - Feedback and Reviews: Regularly collecting user feedback and reviews to gauge satisfaction and areas for improvement.
   - Frequency of On-Chain Interactions: Given our aim to lower the threshold of on-chain interactions, an increase in frequency would indicate our success in this regard.

4. Infrastructure Impact:
   - Integration with Other Platforms: The number of platforms integrating or partnering with GasLockR, indicating our value proposition in the wider blockchain ecosystem.

In essence, we're not just looking at raw numbers, but a holistic representation of our project's impact, from user adoption to the very enhancement of blockchain infrastructure services.
