reject extended private keys when creating a terminal watch only wallet, and show import errors

This commit fixes a bug in Sparrow Wallet's terminal (command-line) watch-only wallet creation. Previously, a user could accidentally paste an extended private key (xprv) into a dialog meant only for public keys or output descriptors, and …

add bitbox02 attestation failed dialog

This commit adds a user-facing warning dialog when a BitBox02 hardware wallet fails an attestation check. Attestation is a process that helps verify the device is genuine and not a counterfeit or tampered unit. Previously, a failed attesta…

improve validation of payjoin proposals, and accept a substituted payment output where a change output is present

This commit strengthens how Sparrow Wallet checks Payjoin proposals received from a payment receiver. Payjoin lets a receiver add their own inputs to a transaction to improve privacy. The changes add missing checks that could previously le…

fix(python/trezorlib): enable entropy check on T1 by default

This commit changes the Trezor Python library so that, when setting up a Trezor Model One (the original Trezor 1 device), it now performs an entropy check by default if the device runs firmware 1.13.1 or newer. Previously, the library only…

fix(simulator): return password error on PIN mismatch in SimulatorLoadAccountSecret

rng: discard 12 words after SEIS clear per RM0432 32.3.7

This commit changes how the COLDCARD hardware wallet's random-number generator (RNG) recovers from a rare 'seed error' condition. The manufacturer is now following an STMicroelectronics guideline to throw away the first 12 random numbers a…

remove unused signature verification results in satochip and keycard signers, note where signatures are verified

This commit removes leftover code that checked whether signatures from hardware card signers were valid, but then threw away the result. The signatures are still verified later by a different part of the wallet when the signed transaction …

Removal of local signature verification calls in hardware signer code pathsAdded comments documenting that signature verification occurs later via PSBT.verifyCombinedSignatures()Unused boolean results indicate the removed checks were dead code rather than active security controls

Why commit watching?

Security should leave a paper trail.

A quiet fix may be responsible caution—or it may leave users unaware that their assets were ever at risk. CommitWatch preserves the evidence, adds context, and tracks whether vendors disclose, acknowledge, and learn.
