This commit only changes the firmware version numbers in a header file (from 12.4.9 beta 2 to 12.5.0 beta 1). It does not modify any executable code, fix any bug, or change any security behavior. There is no security relevance visible in t…
177a1177by Adam Tucker+3−31 fileThis commit is a performance and user-experience improvement for Zcash batch transactions on the Keystone 3 hardware wallet. It speeds up processing of multiple Zcash PCZTs by caching decoded viewing keys and spend-authorization keys acros…
be657651by Adam Tucker+910−25212 filesThis commit adds a safety check for Zcash batch transactions on Keystone hardware wallets. Before fully parsing a batch of PCZT (Zcash transaction) data, the firmware now reads the declared number of items and rejects it if it exceeds 50. …
c3c717c9by Adam Tucker+60−13 filesThis commit removes a duplicate entry in a list of internal software signal names used by the device's user interface. The duplicate would have caused the firmware to fail compilation, so the change is a straightforward build fix with no s…
1a8cfcb4by Adam Tucker+0−11 fileThis commit simply switches a software dependency from a temporary community fork back to the project's own official upstream repository. The code being used is the same feature (Zcash batch registry support); it has just been merged into …
ef575e15by Adam Tucker+3−32 filesThis commit fixes a security gap in the Keystone hardware wallet's Zcash transaction handling. The older 'legacy' code path was only designed to inspect and sign transparent (non-private) Zcash transactions, but its safety check only block…
c0faa647by Adam Tucker+21−124 filesThis commit only adds a new automated test for Zcash transparent output parsing. It builds a sample pay-to-public-key-hash (p2pkh) output at runtime and checks that the parser correctly extracts the recipient address, value, and 'not chang…
612a4a94by Adam Tucker+37−01 fileThis commit is a pure code-style refactor in a Zcash transaction-checking function. It rewrites nested match statements into a flatter let-else and map_or pattern, but the commit message and diff show no change to the actual logic, error m…
e76f36e3by Adam Tucker+31−361 fileThis commit is purely a code-style cleanup: it replaces repeated `alloc::format!` and `alloc::vec!` calls with a single `use` import at the top of the file. The commit message explicitly states there is no behavior change, and the diff con…
658f5b57by Adam Tucker+10−101 fileThis commit is a code cleanup (refactor) in the Zcash PCZT handling code. It removes an unused internal check and an unused function parameter, renames a helper function, and changes its return type. The commit message explicitly states th…
d6e8bbdeby Adam Tucker+14−232 filesThis is a code cleanup change with no security impact. It replaces free-form text labels like "Orchard" and "Ironwood" with a fixed enum type when checking, parsing, and signing Zcash shielded transaction bundles. The actual behavior and e…
28380dacby Adam Tucker+57−384 filesThis commit adds support for a new Zcash transaction format called Ironwood PCZT to the Keystone hardware wallet firmware. It also hardens the wallet against several real attack scenarios: legacy code paths now refuse to handle the new for…
c28575beby Adam Tucker+2036−2709 filesThis commit updates the Zcash-related Rust libraries inside the Keystone 3 firmware to newer versions. It also makes small code changes so the firmware keeps compiling with the new library APIs, removes some old tests that no longer work w…
4487747fby Adam Tucker+201−43710 filesThis commit is a pure internal code reorganization (refactor) for Zcash PCZT handling. It moves helper functions around, renames some UI rendering code, and adds a shared PCZT parsing helper, but the commit message and diff show no intenti…
