Address-Poisoning Cost: 140 ETH Lost — Tighten Wallet Hygiene Now

I note a user lost 140 ETH (about $636,000) after an address-poisoning attack replaced the intended recipient address. This was a direct user-level scam, not a protocol exploit, but the financial consequences were severe.

I see this as a growing operational risk for Ethereum users: clipboard or UI manipulation can cause high-value transfers to malicious addresses that are irreversible on-chain. Small mistakes become catastrophic when large amounts are involved.

I recommend always verifying addresses through multiple methods — hardware wallet address screens, ENS names with reverse resolution, address books, or test transactions — and avoiding copy‑paste for large transfers. Treat this incident as a warning to tighten personal custody practices immediately.
