# AML check

> What an AML check is, which deposits and withdrawals are screened, and what happens to high-risk funds.

An AML check (Anti-Money Laundering) shows whether a crypto address is linked to fraud, sanctions, darknet markets, stolen funds, mixers, or other risks. PS Wallet screens addresses using a specialized blockchain analytics service.

The check protects both you and the wallet: "dirty" coins are not mixed with your other funds, and your withdrawals do not go to dangerous addresses.

## What is checked

- **Deposits** above a certain amount. The amount is calculated across all deposits to your account over the last 24 hours, so splitting a large transfer into parts won't help. Transfers from blacklisted addresses are checked regardless of the amount.
- **Withdrawals** to external addresses above a certain amount. The recipient's address is checked.

## How the decision is made

Based on the check result, the address is assigned a risk level:

- **Low**: the deposit is credited, and the withdrawal is sent as usual. Most checks pass unnoticed.
- **Medium**: the security team reviews the transaction manually. Until a decision is made, the deposit is not credited and the withdrawal is not sent.
- **High**: the deposit is frozen, and the withdrawal is canceled.

## If a deposit is frozen

The bot will send you the message "The security team rejected the deposit". If an email is linked to your account, a copy will be sent there as well.

What happens next:

1. **The funds are not credited to your balance.** In the history, the deposit will be marked "The security team rejected the transaction".
2. **The deposit address changes.** A new address is issued for the account, and the bot will tell you about it in a separate message: "Deposit address for account … has been changed". Deposits to the old address will no longer be credited.
3. **The funds can be returned to the sender.** To do this, you need to pay a return fee.

How to return the funds:

1. Open the "History" tab and tap the frozen deposit.
2. Check the fee amount and the payment deadline on the transaction card.
3. Tap "Pay fee". The fee is charged from the same account, so it must have enough funds.

After payment, you will see "Return of funds to the sender is being processed", and the coins will be sent to the address they came from.

> [!WARNING]
> If a deadline is shown on the transaction card and in the bot's message, you must pay for the return before it. If you miss it, the funds can no longer be returned. If there is no deadline, the security team will decide what happens to the unpaid funds.

Returning TRX, BNB, ETH, and GRAM via the button is not available. The wallet will show "This deposit is returned by support — contact us".

## If a withdrawal is canceled

If the recipient's address is high-risk, the withdrawal is canceled before it is sent to the network. The amount, including the fee, is returned to your account, and the bot sends the message "The security team rejected the transaction".

Withdrawals to some addresses are prohibited in advance. In that case, the wallet will immediately show "Sending to this address is prohibited by the security team".

## How to avoid problems

- Accept cryptocurrency only from people and services you trust.
- Do not buy cryptocurrency from random sellers or from dubious exchangers.
- Before a large withdrawal, make sure the recipient's address belongs to a reliable exchange or wallet.
- Use the current deposit address from the "Deposit" section.

:::details Why did my deposit address change?
Funds with a high risk level were received at the old address. To prevent such funds from mixing with the rest, the account is issued a new address. Use only the new address.
