The final week of the @colosseum hackathon, I’ve spent the last few days polishing @cardmartapp and reflecting on why I built it in the first place
Watching my Thai friends here, I realized how much exhausting effort collectors put into just trying to find the next card that might pump.
They spend hours doing research
> opening eBay to check price feeds, cross-referencing SNKRDUNK to compare series
> tracking set drops
> hunting for auctions in Facebook groups
> driving across town to local stores just to buy a single card
All while hoping it actually goes up in value
What is CardMart
Think of it like TradingView for TCG the ultimate data platform and secure global marketplace bringing everything into one place
What I've Done Over the Past Few Days
> All-in-One Data & Insights: Heatmaps, comparison tables, price feeds linked directly to eBay, trend tracking, and upcoming set-drop calendars.
> Trading & Market Activity: Live auctions, buyer/seller insights, and leaderboards showing top profit-earners.
> AI Buying Agent & Direct Messaging: Users can set automated tasks so they don't have to waste hours checking 20+ bookmarked posts or refreshing bids every hour, complete with built-in messaging for smooth negotiations.
> Secure Backoffice: Robust admin tools to manage safe physical verification and escrow.
What's next
I’m currently thinking of daily retention and rewards to keep users coming back every single day. While I looked into gacha mechanics that every web3 platform do, we don't have enough physical inventory in our vault yet, and it might be too complicated for traditional collectors right now, so that's definitely a feature for the future.
For the colosseum are nearly finished this week, focusing heavily on UI polish so users can dive right in
Need some feedback :)

Have you ever felt like tracking just one trading card is a nightmare opening 10 different tabs just to check live prices, holder stats, upcoming set drops, and which series is likely to pump next?
