The problem WRAPD solves

WRAPD serves as a powerful tool for users to track, analyze, and archive their yearly blockchain activity on the Arbitrum network. Here's how it enhances their blockchain experience:

Personalized Analytics: Get a detailed, easy-to-understand breakdown of your on-chain activity over the year. This includes portfolio performance, NFTs acquired or traded, favourite coins, most expensive token , and airdrops earned.

Better Decision Making: By consolidating all these crucial metrics into one comprehensive report, Arbitrum Annual empowers users to make more informed decisions about their future blockchain engagements based on their past activities and trends.

Unique Memorabilia: The ability to mint your yearly summary into a non-transferrable NFT adds a distinct, personal narrative to your blockchain journey. This NFT serves as a digital keepsake, encapsulating your blockchain activity in an immutable format.

Security and Privacy: As the NFT is non-transferrable, your yearly summary remains securely with you, ensuring privacy of information.

Challenges we ran into

Data Fetching and Aggregation

Our biggest hurdle was fetching and aggregating a comprehensive set of on-chain activities for each user in an efficient manner. With the vast amount of data to process and the need for near real-time responses, we initially faced problems including long API response times, excessive resource consumption, and difficulties in managing data consistency.

To overcome this, we implemented:

Optimized Data Fetching: After digging through our data-fetching logic, we decided to leverage Alchemy for its ability to fetch only the required fields instead of the entire data set, reducing the payload size of our network requests.
