This commit is a code cleanup in Trezor's Ethereum app. It replaces a pre-built lookup table of known smart-contract addresses with a generated template and a helper function that searches the same data on demand. The visible behavior—such…

fix(core): solana transfer showing LUT address

This update fixes a display bug in Trezor's Solana token transfer screens. When a transaction destination was stored in an off-device 'address lookup table' (ALT), the device used to show the lookup table's own address as the recipient, in…

feat(core/eckhart): change connection indicator

This commit is a purely cosmetic change to the Trezor hardware wallet's user interface. It removes the small inner rectangle from a green 'connected' status indicator on the T3W1 (Eckhart) device model, leaving only the outer circle. The l…
