This commit makes a single on-screen message scrollable. When swapping cryptocurrency, the destination amount can be very long and previously may have been cut off or unreadable. The change lets the user scroll through the full text before…
c116b0a8by Cedric Wiese+1−01 fileThis commit adds support for EIP-1559 Ethereum transactions in the BitBox02's payment-request (swap) feature. It lets users verify and sign Ethereum and ERC-20 token swaps that include a merchant payment request, similar to what already ex…
38d26b42by Cedric Wiese+504−285 filesThis commit is a simple code cleanup: it moves two existing blocks of Ethereum fee-verification logic into new helper functions without changing what the code actually does. There is no visible security fix or behavior change.
f3aeae28by Cedric Wiese+31−111 fileThis commit adds a new optional 'payment request' field to Ethereum EIP-1559 signing requests in the BitBox02 firmware's protocol definitions and generated code. It does not contain any actual implementation of how that field is processed,…
21a01dcaby Cedric Wiese+63−435 filesThis commit is a code cleanup that makes the payment-request code less Bitcoin-specific so it can be reused for other coins in the future. It does not add new user-facing features or fix a known bug. The changes move amount formatting and …
b7e8f580by Cedric Wiese+281−982 filesThis commit is a pure code refactor: it moves the payment_request module from the bitcoin-specific directory up to the general API directory. The actual logic, security checks, and behavior of the payment request code are unchanged. No new…
b627ca50by Cedric Wiese+1376−13764 filesThis commit adds support for deriving and verifying Bitcoin-family destination addresses inside payment-request memos used for coin swaps. It extends the existing Ethereum-only address-derivation feature to also cover BTC/LTC, and validate…
9eb4fd04by Cedric Wiese+520−415 filesThis commit adds a new on-device user interface flow for cryptocurrency swaps, where a user can exchange Bitcoin or Litecoin for an Ethereum-like coin through a payment request. The code adds validation rules and user confirmation screens …
cc45c948by Cedric Wiese+610−12 filesThis is a minor Python import cleanup in a developer/test script. It changes how one internal class is imported so that the script works reliably when installed in 'editable' mode. There is no security issue here.
faebccd4by Cedric Wiese+3−21 fileThis commit adds a new trusted Bitcoin payment-request signer called SWAPKIT to the BitBox02 hardware wallet. It also makes matching more flexible for SWAPKIT so names like 'swapkit (Provider)' or 'SwapKit' are accepted. The change is a ro…
39659c65by Cedric Wiese+37−21 fileThis is a build-system cleanup, not a security fix. It moves test-only fake hardware code into a lower-level Rust crate and adds a linker trick so the fake disk storage implementation is not accidentally left out when building the desktop …
191a5982by Cedric Wiese+38−278 filesThis commit only changes how wallet addresses are shown on the BitBox02 screen. It inserts spaces every four characters (for example, a Bitcoin address becomes "bc1q k5f9 em9q ..." instead of one long string). There is no code that changes…
a871abc7by Cedric Wiese+215−7812 filesThis commit adds a new 'coin purchase memo' feature to BitBox02 payment requests. It lets a payment request include details about a separate coin purchase (e.g., '0.25 ETH to address 0x...') and verifies that the listed Ethereum address re…
10746100by cedwies+419−418 filesThis commit fixes a typo-like bug in the BitBox02 hardware wallet's Ethereum transaction signing code. The firmware was supposed to reject a 'max_fee_per_gas' value that has an unnecessary leading zero byte, but it was accidentally checkin…
ee6e1ceeby cedwies+27−11 fileThis commit fixes a bug in the BitBox02 hardware wallet firmware where two Bluetooth privacy values were accidentally created from overlapping random bytes. The device intended to use the first 16 random bytes for a secret key (IRK) and a …
66aaab28by cedwies+55−12 filesThis commit is a straightforward internal refactoring: it moves the device-reboot-into-bootloader function behind a new 'System' hardware-abstraction trait so the rest of the Rust code calls it through a generic interface rather than direc…
afcdcbe3by cedwies+40−83 filesThis commit is a code cleanup that moves multisig account storage operations behind a hardware-abstraction layer so tests can use a fake memory instead of real device memory. It does not appear to fix or introduce a security vulnerability.…
508cf98fby cedwies+212−996 filesThis commit only fixes the formatting of license headers in automatically generated Python type-stub files. It moves the SPDX license notice from a standalone comment line into the generated docstring block. There is no change to program l…
cb71f488by cedwies+11−3111 filesThis commit is a code cleanup and test-improvement change. It moves two device-attestation helper functions from a direct hardware call into a software 'hardware abstraction layer' (HAL) so the code can be tested without the real device. I…
45355e61by cedwies+147−62 filesThis commit is a straightforward internal refactoring: it moves access to a device secret called the 'salt root' behind an existing hardware-abstraction layer so that automated tests can use a fake memory instead of real device memory. The…
