Frequently asked questions
What data does Clams import from OpenNode?
Clams imports your payment history from OpenNode including payment amounts, timestamps, fees, and fiat conversion rates. This gives you accurate cost basis for capital gains calculations.
Does Clams access my OpenNode account?
No. CSV import is completely offline. You export your transaction history from OpenNode and import the file into Clams. No connection to your OpenNode account is required.
Can I track multiple OpenNode accounts?
Yes. Import each OpenNode account's CSV separately in Clams. Each gets independent tracking and reporting.
Does Clams track both on-chain and Lightning payments?
Yes. OpenNode's CSV export includes both on-chain and Lightning payments. Clams imports all payment types with their associated metadata.
How do I get capital gains reports from my OpenNode payments?
Export your transaction history from OpenNode as CSV and import into Clams. Clams uses your payment data to calculate cost basis. Export capital gains reports for tax preparation from the Exports widget.
What if my CSV format isn't recognized?
Use our custom import tool to map columns manually if the OpenNode format isn't automatically recognized. The tool lets you specify which columns contain dates, amounts, and transaction types.
