Challenges I ran into

✅ Duplicate Unique IDs
The possibility of duplicate unique IDs could undermine the credibility of carbon credits traded on the platform.

Solution : Implemented secure hashing algorithms and a mapping to store and verify unique IDs. This approach successfully addressed the issue and ensured the uniqueness and integrity of each carbon credit NFT.

✅ Data Integrity
Ensuring the accuracy and reliability of the carbon credit data is critical to the platform's success.

Solution: Introduced validation checks for the information associated with each carbon credit before minting the NFT. This process included verifying the origin, eligibility, and carbon reduction impact of the project or activity, ensuring the credibility of the carbon credits.

✅ Unauthorized Access
Limiting access to critical functions in the smart contracts was necessary to prevent unauthorized minting or modifications of carbon credits.

Solution: Implemented proper access control using OpenZeppelin's Ownable contract or Role-Based Access Control (RBAC) to restrict access to critical functions. This measure helped maintain the integrity of the platform and prevented unauthorized actions.

✅ User Interface
Challenges in having a smooth frontend deployment due to technical difficulties.
