why can't hardware wallets like @Ledger decode the vast majority of transactions in 2025? isn't it as easy as storing a function selector database and picking the one that matches the calldata the most? Need to blind-sign everything. From a UX perspective, the firmware & apps haven't evolved since I first used them in 2017.

@0xmishoko @Ledger I don't know how these Ledger apps work in detail but I'd put it in the Ethereum app, not the firmware itself, and then you just update the Ethereum app once every month with new signatures.
