Inspiration
RedCalls was born from the realization that Reddit often signals early crypto trends — but manually reading through hundreds of posts is inefficient. We wanted a tool that automatically detects which crypto projects are being discussed and whether the sentiment is positive or negative. Our goal: save time and make better, faster decisions.
What it does
RedCalls analyzes Reddit posts in real time using NLP to classify sentiment and track how often each coin is mentioned. From that, we generate sentiment trends, attention timelines, and a current top 5 list of trending coins.
How we built it
Using Python and the praw library, we collected Reddit data, applied sentiment scoring, aggregated results, and built simple visualizations. Data can be exported as CSV or JSON for further use.
Challenges we ran into
We faced Reddit API rate limits, noisy and sarcastic language that challenged sentiment analysis, and mapping multiple aliases for coins like "$ETH" vs. "Ethereum".
Accomplishments that we're proud of
We built a working prototype in just a few hours that delivers meaningful insights and is flexible enough to scale and adapt to more data sources or user needs.
What we learned
Crypto sentiment is hard to read — but not impossible. Reddit remains one of the most valuable raw sources if analyzed correctly. And fast, focused teamwork gets results quickly.
What's next for RedCalls
We plan to improve the sentiment model, add more data sources (like Telegram or Discord), and integrate RedCalls into trading dashboards or research tools. This is just the beginning.
