Break down each one in more detail: NFTs, Mixers, and DeFi laundering tricks. Each plays a unique role in modern money laundering, and kleptocrats, cybercriminals, and fraudsters are getting increasingly clever.

1. NFTs (Non-Fungible Tokens) for Laundering

The Trick:

Use self-owned or complicit wallets to buy and sell digital art NFTs at inflated prices, masking illicit money as 'art investment.'

How It Works:

• The launderer mints or buys a low-value NFT.

• They then 'sell it to themselves using a different wallet for $100,000 or more, using crypto obtained from criminal activity.

• That wallet then sells it to another buyer, perhaps a real collector, and claims the money is from 'art profits'.

Why It's Ideal:

• NFT platforms often have no KYC checks.

• Values are subjective, making overpricing harder to question.

• Records exist on-chain, but real identities don't.

Real Case: In 2022, the U.S. Treasury warned that NFTs can be used to 'launder proceeds of fraud or corruption through high-value art transactions.'

2. Crypto Mixers (a.k.a. Tumblers)

The Trick:

Obscure the trail of funds by mixing dirty crypto with clean crypto from multiple sources.

How It Works:

• You send 10 BTC to a mixer like Tornado Cash, ChipMixer, or Blender.io.

• The mixer pools it with funds from thousands of users.

• You receive a different 10 BTC, with no direct link to your original source.

What It Hides:

• Sender and recipient

• Transaction history

• Original source of funds

These are now being shut down or sanctioned by governments, Tornado Cash was sanctioned by the U.S. in 2022 for laundering over $7 billion, including North Korean cyber heists.

3. DeFi Laundering Tricks (Decentralized Finance)

The Trick:

Exploit decentralized platforms with no identity checks to layer and disguise illicit transactions.

Swapping Between Tokens

• Use platforms like Uniswap, SushiSwap, or 1inch to convert dirty tokens into other tokens dozens of times.

• Every swap generates a new transaction path.

Example: USDT -> DAI -> ETH -> wrapped BTC -> obscure token -. back to USDT.

Flash Loans

• Borrow millions with zero collateral, as long as you pay it back within the same transaction.

• Can be used to temporarily inflate prices, simulate trading activity, or manipulate pools.

Yield Farming & Staking

• Launderers stake illicit tokens on DeFi platforms to earn rewards (i.e., passive 'clean' income).

• These staking rewards can then be moved to a compliant wallet and withdrawn.

Synthetic Assets

• Launderers create or trade in synthetic versions of stocks, gold, or fiat.

• These mimic real-world assets but are purely digital and unregulated.

Many criminals use DeFi bridges to move assets across blockchains (e.g., Ethereum to BNB Chain) to break surveillance trails.
