Frequently asked questions
What data does Clams import from Blockstream Jade?
Clams imports all addresses derived from your xPub, incoming and outgoing transactions, UTXOs, and calculates cost basis per UTXO. Your signing keys never leave the Jade.
Does Clams access my private keys?
No. Clams uses watch-only access via xPub. Your signing keys stay secure on your Jade device. The xPub only allows Clams to view addresses and transactions, not spend funds.
Can I use Jade in air-gapped mode?
Yes. Jade supports fully air-gapped operation via QR codes. Export your xPub via QR and add it to Clams. Your Jade never needs to connect to a computer.
How do I get capital gains reports from my Jade transactions?
Export your xPub from Blockstream Green and add it to Clams. Clams calculates cost basis for every UTXO and tracks capital gains when you spend. Export reports from the Exports widget.
Do I need my Jade connected to sync new transactions?
No. Once you've added the xPub to Clams, you can sync at anytime. Your Jade can stay safely disconnected or air-gapped.
