test: make device signing cases more granular

This commit only changes test code. It makes the automated test suite more flexible by letting device simulators opt out of one specific test case involving unusual key derivation paths, while still running the rest of the tests. There is …

ledger: have sign_psbt return SignPsbtYieldedObject

This commit is a straightforward internal code refactor for Ledger hardware wallet support. It changes the data structure returned when signing a Bitcoin transaction from a simple tuple of raw bytes to a more descriptive object that can ca…

ledger: handle script path signatures

This commit updates the Ledger hardware wallet driver in HWI so it can correctly store Taproot script-path signatures in a PSBT, not just key-path signatures. Previously, the code had a placeholder that always treated any Taproot signature…

psbt: don't overwrite PSBTv2 tx version and fallback locktime

This commit fixes a bug in how the HWI library handles a newer Bitcoin transaction format called PSBTv2. Previously, when converting or setting up a PSBTv2 object, the code would accidentally overwrite the transaction's version number and …

wallet: reject sendtoaddress and sendmany for external signers

This change makes Bitcoin Core refuse two older wallet commands (sendtoaddress and sendmany) when the wallet is controlled by an external signer, such as a hardware wallet. Previously these commands could be called but would fail in a conf…

Prevents misuse of RPCs that cannot complete signing for external-signer walletsAdds explicit error path instead of relying on downstream failureAdds functional test coverage for the new error behavior

refactor: use PSBTFillOptions for filling and signing

This is a straightforward code cleanup (refactor) that bundles several PSBT signing options into a single structure. It does not change what the software does; it only changes how the options are passed around internally. There is no secur…

refactor: use SignOptions for MutableTransactionSignatureCreator

This commit is a straightforward code cleanup: it replaces a raw integer parameter representing the signature hash type with a small structured options object called SignOptions. All call sites are updated to pass the same value inside the…
