Why this check exists
On October 29, 2026 a compromised third-party script swept$2.64M from 726 Polymarket accounts in under an hour — and the same day Binance lost $6.3B, the largest exchange theft on record. Neither attack broke wallet software. Both reused permissions users had granted long before. That is the exposure this check surfaces for your wallet: read-only, in 30 seconds, with a fix guide for every red flag.
Deep-dive: how both breaches worked, minute by minute.
What the check covers
EIP-7702 delegation
Your account quietly pointing at a stranger's contract — the mechanism behind the October drainer chains.
How to revoke →Token approvals
Unlimited allowances signed months ago for apps you no longer use — the exact surface the Oct 29 drainer reused.
How to clear →Session hygiene
Stale connected sessions that survived a frontend breach — valid until you kill them.

Can this check steal my funds?
No. A read-only connection cannot move, swap, or sign anything. If any popup asks for a signature or your seed phrase, that's the follow-up scam — close it.
Why connect at all?
The address-only delegation checker works with zero connection. Connecting adds live approvals and session state on top — still read-only.
What happens after the check?
Each red flag links to its step-by-step fix. Most fixes take under two minutes. Clean result: set a monthly cadence via the 10-step hardening guide.
30 seconds now beats $2.64M later
The 726 drained wallets had one thing in common: exposure they didn't know about.
