The problem CryptoTrace solves

Streamlined Blockchain Access:
Users can easily log in and access multiple blockchain networks (like Base Sepolia, Aptos Testnet, and Aptos Devnet) through a single platform, saving time and avoiding the complexity of using multiple tools.

Real-Time Transaction Data:
Automatically fetch transaction data and contract deployment details from blockchain explorers, allowing users to gain insights without manually searching or processing data.

Predicting Gas Fees:
The platform uses machine learning to predict future gas fees, helping users optimize their transactions by understanding potential costs in advance.

Easier Developer Integration:
Developers can integrate blockchain insights directly into their applications with the CryptoTrace NPM package, simplifying backend and frontend development tasks.

Secure and Efficient Workflow:
With secure authentication through Okto SDK, users can safely access the system and perform tasks without worrying about security breaches or complex login procedures.

Challenges we ran into

Cross-Chain Integration:
Integrating multiple blockchains like Base Sepolia and Aptos Testnet posed a challenge because each chain has its own set of APIs and data formats.
Solution: We developed a modular architecture that allows us to easily add new blockchains in the future while standardizing how data is fetched and processed.

Data Fetching Latency:
Blockchain explorers sometimes experience delays in providing real-time data, causing slower updates.
Solution: We implemented caching mechanisms and scheduled data fetches to ensure that the platform displays up-to-date information without overwhelming external APIs.

Gas Fee Prediction Accuracy:
Predicting gas fees using machine learning was tricky due to the volatility and complexity of blockchain networks.
Solution: We used historical data to train our models, continuously refined the model with new data, and adjusted for network conditions to improve the predictions.

API Rate Limits:
Many blockchain explorer APIs have rate limits, which restricted the number of requests we could make within a short period.
Solution: We implemented request batching and asynchronous data fetching to optimize the number of API calls and avoid hitting rate limits.

Security Concerns:
Ensuring secure user authentication and protecting sensitive blockchain data was critical.
Solution: We used Okto SDK for secure user logins and followed best practices for data encryption and access control to safeguard user data.
