A wallet can look completely clean — no direct sanctions hits, no darknet contacts — and still trigger an exchange freeze. The reason: layering. Dirty funds pass through multiple clean wallets before reaching you, but the trail remains on-chain.
Layering is the second stage of money laundering. After placement (converting illegal proceeds into crypto), the funds are moved through a series of wallets to obscure the origin. Each transfer creates a new 'hop' in the transaction graph. By hop 3 or 4, the connection to the original dirty source may look distant — but it is still traceable.
Modern AML engines like Scorechain trace up to 4 hops in both directions from any wallet. A wallet that received funds two hops from a darknet market will carry indirect exposure — even if the wallet itself has never directly interacted with flagged entities.
Imagine this chain: Darknet market → Wallet A → Wallet B → Wallet C (yours). Your wallet (C) looks clean — no direct darknet contact. But you received funds from B, which received from A, which is directly linked to the darknet market. At hop-2 exposure, some exchanges will flag your account.
At hop-3 or hop-4, the risk score is typically lower, but high-volume exchanges with strict compliance policies may still investigate. The key metric is not just the existence of the link but the amount and proximity.
Before accepting any significant crypto payment, run an AML check on the sender's wallet. A hop-1 or hop-2 connection to flagged entities will show up as a medium or high risk score (31–100). A score below 30 means the tracing engine found no significant exposure within 4 hops.
