A look at crypto money laundering in 2022: illicit addresses sent nearly $23.8B, up 68% YoY, four addresses got $1B+ combined, DeFi got record funds, and more
The 2023 Crypto Crime Report — Money laundering is crucial to all financially motivated crime because it's what enables criminals …
Context & Ripple Effects
Chainalysis's annual laundering series has been climbing through the cycle: criminals moved $8.6B in 2021, when centralized exchanges still took 47% of illicit funds and DeFi just 17%. The 2023 Crypto Crime Report marks the break point — nearly $23.8B laundered in 2022, up 68%, with DeFi absorbing a record share and four addresses alone clearing $1B or more.
The report also foreshadows how the story unwinds: prior Chainalysis work showed laundering is highly concentrated — just five receiving services handled 55% of all 2020 laundering through 270 deposit addresses — and the following year's data confirmed the reversal, with laundering falling 29.5% to $22.2B in 2023 as five off-ramp services captured 71.7% of flows.
First-order effects
- DeFi protocols displace centralized exchanges as the default laundering venue, shifting the compliance burden from KYC'd off-ramps to largely permissionless smart contracts that had no equivalent controls in place during 2022.
- The four $1B+ addresses give investigators named, on-chain targets: unlike dispersed criminal wallets, these concentrated hubs are individually traceable and sanctionable.
Second-order effects
- Because flows pool into a handful of services and addresses, enforcement aimed at those chokepoints moves the aggregate number — the pattern behind the 29.5% drop to $22.2B in 2023 once off-ramps were squeezed.
- DeFi's record share forces the sector toward on-chain screening tools and sanctions-list integration, since traditional exchange KYC no longer intercepts funds before they hit liquidity pools.
Third-order effects
- If laundering keeps concentrating into a few identifiable services, crypto crime control becomes a chokepoint-enforcement regime — sanction or shutter five entities and most of the flow is disrupted — rather than policing millions of individual transactions.
- The 2022 peak-to-2023-decline arc suggests laundering volume tracks the broader illicit-inflow cycle rather than growing structurally, which strengthens the case that DeFi can be brought inside the compliance perimeter without eliminating it.
The trend: Crypto money laundering is consolidating into a small set of high-throughput venues — first exchanges, then DeFi — making total volumes swing with enforcement against a handful of chokepoints rather than with the number of criminals.
