Frequently asked questions
What data does Clams import from Strike?
Clams imports your buy and sell history from Strike including purchase amounts, prices paid, timestamps, and fees. This gives you accurate cost basis for capital gains calculations.
Does Clams access my Strike account?
No. CSV import is completely offline. You export your transaction history from Strike and import the file into Clams. No connection to your Strike account is required.
Can I track multiple Strike accounts?
Yes. Import each Strike account's CSV separately in Clams. Each gets independent tracking and reporting.
Does Clams track my purchase price from Strike?
Yes. The Strike CSV export includes purchase prices. Clams uses this to calculate accurate cost basis for your Bitcoin. When you later sell or spend, capital gains are calculated correctly.
How do I get capital gains reports from my Strike transactions?
Export your transaction history from Strike as CSV and import into Clams. Clams uses your purchase prices to calculate cost basis. Export capital gains reports for tax preparation from the Exports widget.
What if my CSV format isn't recognized?
