Woofun AI reports that ZachXBT argues a dedicated iPhone provides better security than traditional hardware wallets due to its hardened operating system, app sandboxing, and larger display. He notes that while hardware wallets isolate private keys, they often fail to display sufficient transaction details, leading users to approve malicious swaps. The proposed solution involves using ERC-7730 to translate raw contract calls into plain language, alongside policy-enforcing wallets with spending caps and withdrawal delays. This approach aims to transform self-custody into a programmable risk system, limiting the authority of a single signature.
