Ethereum just got a new security primitive that could stop wallet drains dead in their tracks.

The setup: instant sends for small amounts, but large transfers get a time delay + can be cancelled by a backup wallet only you control.

Even if an attacker gets your main key, they can't disable the guardian for 7 days.

This is basically a panic button built into your wallet architecture. No more watching helplessly as your funds vanish in seconds like the Binance hack.

Still a prototype, but this is the kind of infra upgrade that could actually matter when the next exploit wave hits.
