The short version

What changed, and why it matters

This commit is a routine build-system housekeeping change. It swaps the Docker image used for automated builds from 'verde' to 'jade_builder', updates the ESP-IDF framework version from 5.4.0 to 5.4.3, adjusts paths to the ESP-IDF installation, and refactors several CI helper scripts. There is no change to the wallet firmware code that handles private keys, transactions, or user data, and no security vulnerability is introduced or fixed in the diff itself.

Recommended action

No security action required. Treat as normal build-maintenance commit. If reviewing for supply-chain assurance, verify the new blockstream/jade_builder image and ESP-IDF 5.4.3 toolchain are built from known, audited sources, but that verification is outside the scope of this code diff.

Security signals we found

No strong security signals were identified.

This commit fixes the use of the "%zu" printf format specifier, which is not supported by the ESP32 toolchain used in this project. The unsupported format could cause log messages and user-facing strings to display incorrect or garbage val…

otp: release md context on failure and clean temporary buffers

This commit fixes cleanup in the one-time-password (OTP) code. Previously, if setting up the cryptographic hash context failed, the code could return without freeing that context, and temporary buffers holding sensitive counter/HMAC data w…
