Crypto exchange emergency security checklist

A crypto exchange emergency security checklist is not a vibe. It is four jobs: lock the login, revoke old contract approvals, move coins to a device whose seed is on steel, and stop photographing that steel. Run it against the 29 October Binance file, then against every other desk you still use.

Parent document: live status. If you still have size on Binance, pair this list with the best cold wallet for crypto safety and, if you need an order book, best Binance alternatives 2026. Phishing spikes on incident days — treat any “support” chat that asks for a seed or a remote-desktop session as hostile, even if the avatar looks official.

  1. 1. Kill SMS 2FA — hardware key only

    Every crypto exchange emergency security checklist starts here because SIM-swap is how “I still had coins on the CEX” turns into zero. YubiKey (FIDO2) on Binance, Bybit, OKX, email. Order two; leave one in a drawer.

  2. 2. Revoke smart-contract approvals

    Unlimited USDT allowances from a 2021 farm will still drain a wallet in 2026. Use a known revoker (Revoke.cash or the explorer’s token-approval tab). This line of the crypto exchange emergency security checklist applies to any hot wallet you connected to a dapp, not just Binance.

  3. 3. Cold wallet + steel seed

    Initialize Ledger, Trezor or Tangem offline. Stamp the words into a Cryptosteel-style plate. Never a screenshot, never iCloud. The crypto exchange emergency security checklist fails if the backup is a photo roll.

  4. 4. Faraday bag and encrypted USB

    Spare keys, a backup Nano, a travel phone — a cheap Faraday pouch is the unglamorous item on a crypto exchange emergency security checklist. Encrypted USB is for documents, not for seed words.

  5. 5. Ignore DMs

    No “Binance support” Telegram. No seed “verification.” The last box on this crypto exchange emergency security checklist is social, not hardware.
