Got it.
So it’s the Claimant unlocking their Tapigner locally, signing a PSBT, then Nunchuk adding its key to comprise the 2 of 3 for transfer of fund and initiate the send?
Essentially the same process as if you signed a “normal” with your recovery key, along with one signature from your client from one of their keys, to make a transfer.
This makes sense.
Thanks for the transparency and education about your product Hugo!
@hugohanoi Are you able to provide a bit more info here?
When Claimant puts in Magic Words and Backup Password from Tapsigner to unlock, and does this in the Nunchuk app, how does this not potentially give Nunchuk access to this key and your key (giving you 2 of 3)?
Just want to be completely clear on this and appreciate your time.

You got it mostly correct the first time.

- Beneficiary selects a withdrawal address
- Sweep transaction is created
- Beneficiary signs the sweep transaction with the recovered Tapsigner key
