  • Auto categorizing of transfers to your other connected wallets

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.

Can I track multiple Strike accounts?

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.
