I’m testing a Liana (v15.0) Simple Inheritance wallet on signet. The recovery key is a 24-word BIP39 seed ([4adc83da/84'/1'/0']tpub...). The timelock has expired and Liana has built the recovery PSBT, but:
- Liana’s "Import mnemonic" screen only shows 12 word boxes
- Sparrow (2.5.6), with the same 24-word seed as a single-sig wpkh wallet, says "No open wallets can sign" for the PSBT
Questions:
- Is there a supported way to sign a Liana recovery PSBT with a 24-word software seed, e.g. via Bitcoin Core (
walletprocesspsbtwith an imported descriptor including the tprv)? - Is the 12-word limit on Liana’s hot-key import intentional?
- For an inheritance key, is 12 words (128-bit) considered sufficient, or should it stay 24?
Signet only, no real funds.
