I'm trying to switch from Coldcard Q to Blockstream Jade Plus.
But it's difficult to enter a lengthy passphrase in small Jade Plus with two keys, and I'm afraid I'll type something incorrectly and create a wallet that I can't get back.
Is it okay to create a seed with dice and enter the seedphrase and a passphrase both in Coldcard Q and Jade Plus, connect coldcard Q to Sparrow in QR airgap mode, obtain the Master fingerprint and xpub, then compare it with Blockstream?
I'm not going to use Coldcard Q for any transactions. So hope there won't be a nonce attack threat.
Is it possible for my seed or passphrase to be leaked by entering it into Coldcard Q?
