The short version

What changed, and why it matters

This commit fixes a visual text-rendering bug in the Trezor hardware wallet's user interface. Specifically, when long cryptocurrency addresses are split into small chunks for easier reading, the last chunk on a screen line was sometimes displayed incorrectly or with a missing '...' ellipsis. The fix changes how the layout code decides when a chunk is the final one and how much space to reserve for the trailing ellipsis. There is no evidence this bug could be exploited to steal funds, bypass security, or alter transaction data.

Recommended action

No security action required. Treat as a normal bug-fix release. Users may update firmware at their convenience to benefit from the corrected address display.

Security signals we found

01

UI rendering/layout fix only

02

No cryptographic, signing, or authorization code changed

03

No buffer overflow, memory corruption, or input validation issue visible

04

Test fixture hashes updated for affected address display screens

test(core/ethereum): EIP-7702 tuple nonce must be non-zero

This commit only changes test data and expected screen fingerprints for Trezor's Ethereum EIP-7702 signing tests. It replaces one test case that used a nonce of 0 with the same scenario using a nonce of 67, because the real-world protocol …

refactor(core): digest EIP-1559/EIP-7702 magic without RLP encoding

This commit is a small internal cleanup in Trezor's Ethereum signing code. It changes how two special 'magic' bytes (the transaction type markers for newer Ethereum transaction formats) are fed into the cryptographic hash. Previously the c…
