The problem

Retail traders juggle exchange tabs, spreadsheets and tax guesses. The useful view is one place that shows what moved, why it matters and what a wallet’s history actually cost.

What we built

  • Markets, coin detail pages, heatmap, events and alerts
  • Exchange comparison with fees, leverage and KYC side by side
  • Daily AI briefing and portfolio tracking
  • Stripe subscriptions with a Free and a Pro plan, plus an admin panel for coins, cron jobs and content

Engineering notes

Money path is separate from content

Checkout and webhooks sit apart from the data pipeline, so a failed market refresh never touches a subscriber’s access.
