Bybit’s hack shows Ethereum’s deep flaw: hardware wallets can't properly verify transactions. Users sign blind.
#Bitcoin's UTXO model, by contrast, ensures clarity in transactions. The difference? A $1.4B mistake. 🪦
@DETERMINISTIC OPTIMISM 🌞 , @Rob Hamilton & @Seardsalmon weigh in. [BR093]
Change verification is a must for wallet security.
