Safe Account Transfer: A Buyer's Playbook for the First 24 Hours

The most dangerous window in the life of a purchased account is the first 24 hours. This is when the previous owner still has recovery vectors, when the exchange's fraud detection is watching for anomalies, and when a single wrong step (changing everything at once, logging in from a bad IP) can trigger a lockout. This playbook is the sequence we recommend to every KYC Marts buyer.

Hour 0: verify, don't act

Before you touch a single setting, log in and confirm the account matches the listing: KYC tier, VIP level, jurisdiction, balances, transaction history. Do not change anything yet. If any of these do not match, contact support before proceeding — you have escrow protection for exactly this reason.

Hour 0–1: session and device audit

Go to the security page and revoke every device session except your current one. Check the login history for the last 30 days and note any IPs that are not yours or the seller's declared IP. If you see anything from a jurisdiction the account was never in, freeze and escalate.

Hour 1–2: rotate 2FA

Remove the old 2FA and set up new 2FA on a device only you control. Do this before changing the password — some exchanges require 2FA to confirm password changes and you do not want to be locked out of your own reset flow. Store the new backup codes in a password manager and print a paper copy.

Hour 2–4: password and email

Change the password to a new long random string. If the exchange allows it, change the associated email to one under your control (this is not always available and often triggers a 24–72 hour withdrawal freeze — plan around it). If the email is stuck as the seller's, treat it as a shared credential and set up unique 2FA on it as well.

Hour 4–24: withdrawal whitelist

Enable withdrawal whitelisting and add your own addresses. Most exchanges impose a 24-hour cooldown before whitelist changes take effect — this is a feature, not a bug. It means an attacker who compromises the account today cannot drain it before you notice tomorrow.

Hour 24: first small test

Deposit a small amount and withdraw a small amount to a whitelisted address. This proves the account is fully functional under your control. Only after this test do you fund the account meaningfully.

The mistakes that cost people money

Changing everything in one hour. Logging in from a VPN with a different IP every session. Adding a withdrawal address and immediately trying to send the full balance. Skipping the device audit because the account "looks fine." Each of these is a fraud signal to the exchange, and stacked together they trigger a compliance review that can freeze the account for weeks.

The one non-negotiable

If anything on the account changes without your action in the first 30 days — a login you did not make, a whitelist change you did not approve, a support ticket you did not open — treat it as a compromise and escalate immediately. Your escrow protection covers this window; use it if you need it.

Taking over an account is not hard. Taking over an account without triggering fraud detection is a discipline. Follow the sequence, do not rush, and the account will serve you for years.
