Chainalysis reports that in 2025, wallets linked to illegal activity raked in at least $154 billion worth of crypto. While shady transactions make up a small slice of the total market, the sheer dollar amounts are huge—so exchanges are stepping up their AML (anti-money laundering) game, using advanced tools to spot sketchy activity and cut down on risk.

What Is an AML Freeze on a Crypto Exchange?

When people talk about an “AML freeze,” they mean a set of actions an exchange can take: extra checks, temporary limits on your account, or even pausing your withdrawals and deposits while they sort things out. The goal? Stop funds that might be tied to illegal stuff from moving through the platform.

Why Do Exchanges Freeze Accounts?

If the exchange’s analytics tools flag your activity as suspicious, or if your transactions touch addresses that have been involved in illegal operations, that’s a red flag. The exchange will launch compliance procedures and may lock down your account to protect itself from regulatory headaches or operational blowback.

How to Lower Your Risk of an AML Freeze

There’s no magic bullet, but playing it safe can seriously reduce your chances:

  • Steer clear of transactions with wallets or counterparties that might be mixed up in something illegal.
  • Keep your transaction history clean and be able to explain where your funds come from.
  • Make sure your account info is up to date and respond quickly if the exchange asks for verification.
  • Stay on top of the platform’s rules and keep an eye out for any notifications from the exchange.

Even if shady deals are rare, the amounts involved are massive—so exchanges are tightening their monitoring, and users need to get serious about compliance if they want to avoid headaches.
