Same wallet data every portfolio tracker already shows. Toggle below: Portfolio is what people check today. Tax reality is the same numbers, reframed as what they'll actually owe, in their own currency.

What this is: a demo of the mechanic, not a finished product. Read-only wallet connection, no custody, free tier. The free view is the hook, the full report, cost-basis method, and filed-ready export live behind a Koinly account, same funnel logic as their existing calculator tools.
Why it works: it reaches people before they've typed "crypto tax" into anything. Someone checking what their bag is worth after a good week gets the tax number in the same glance, before the anxiety turns into a search someone else is already bidding on.
