Peel Chain
A peel chain is a laundering pattern where a wallet repeatedly sends most of its balance forward to a new address while "peeling off" a small amount at each step, typically toward an exchange. It produces a long, thin sequence of transactions rather than a single large movement.

A peel chain is a laundering pattern where a wallet repeatedly sends most of its balance forward to a new address while "peeling off" a small amount at each step, typically toward an exchange. It produces a long, thin sequence of transactions rather than a single large movement.
What it means
The pattern resembles peeling layers off an onion: each transaction takes the bulk of the remaining balance and moves it to the next hop, leaving a small residual amount at the current address, then repeats. Over many hops, this creates a long visual chain in a transaction graph, distinct from the branching, one-to-many structure of a fan-out or the pooling structure of a mixer.
Peel chains are effective at obscuring the ultimate destination because each individual hop looks unremarkable on its own — a normal-sized transfer between two wallets — and only becomes suspicious when the entire sequence is viewed together. This is precisely why automated pattern detection, rather than manual review of individual transactions, is necessary to catch it reliably.
Real-world example
Bitcoin mixing services and individual launderers alike have used peel chains for years, moving stolen or illicit funds through dozens of intermediate addresses before a final small peel lands at an exchange deposit address for cash-out.
