AML in crypto is the set of laws and exchange controls that screen wallets and transactions to stop illicit funds from being laundered; Plastron lets you see your own wallet from that compliance perspective, free.

Anti-money laundering refers to the set of laws, regulations, and compliance practices designed to prevent criminals from disguising illegally obtained money as legitimate funds. In traditional finance, AML compliance means banks verify customer identities, monitor transactions for unusual patterns, and file suspicious activity reports with government financial intelligence units. In crypto, the same basic goals apply, but the technical reality of blockchain — pseudonymous addresses, programmable contracts, global accessibility — creates a compliance environment that is both more transparent and more complex. Every transaction on a public blockchain is permanently recorded and traceable, which means AML investigators can follow fund flows with precision that is impossible in traditional cash transactions. At the same time, the volume of blockchain transactions, the speed of cross-border transfers, and the use of smart contracts to obscure fund origins all create new challenges. For individual crypto users, AML matters because every regulated exchange operates an AML compliance programme. When you deposit to Coinbase, Kraken, Binance, or any other regulated exchange, your wallet is automatically checked against sanctions lists and AML risk databases. If your wallet has interacted with a flagged address — a sanctioned mixer, a darknet market, a hack-related wallet — the exchange's system will flag your deposit. You do not need to be a money launderer for this to happen; accidental exposure through DeFi, P2P trading, or receiving funds from a flagged counterparty is common. Understanding how AML works in crypto is the first step to understanding why wallet screening matters.
