feat(clear_signing): WETH wrap and deposit

This commit adds user-friendly on-screen labels for wrapping and unwrapping Ether using the popular WETH token contract on several Ethereum-like networks. It does not change transaction security rules; it only makes the device show clearer…

feat(core): add chunkify param to TronSignTx

This commit adds a new optional 'chunkify' setting to Tron transaction signing on Trezor hardware wallets. When enabled, addresses are shown on the device screen in small groups of characters (chunks of 4) instead of one long string, makin…

feat(tools): script to verify signed firmwares

This commit adds a new helper script that lets developers check whether a signed Trezor firmware file truly matches its unsigned counterpart and whether its digital signature is valid. It is a defensive verification tool, not a fix for a s…

fix(core): fix overflowing text in Delizia bld

This commit shortens two on-screen text labels in the Trezor bootloader from 'INSTALL FIRMWARE' to 'INSTALL FW' and 'UPDATE FIRMWARE' to 'UPDATE FW'. The change is purely cosmetic, intended to stop the text from overflowing its display are…

None identified. The change is a UI text truncation to prevent label overflow.
