What is AML?

Anti-money-laundering rules require businesses that move money to know their customers, monitor for suspicious flows, and report to regulators: KYC is the identity-collection limb, AML the ongoing surveillance one.

In crypto the obligations attach to the same chokepoints as in fiat: the on-ramps, the exchanges, the processors. Non-custodial settlement between self-held wallets sits largely outside them, which is exactly why jurisdiction and scale determine what applies to you.

How AML works

Anti-money-laundering rules are the obligations placed on businesses that move money: know who you are dealing with, watch for suspicious patterns, file reports on defined events, and keep records. The framework binds banks, processors, exchanges, and ramps, each at its own boundary, and KYC is its identity-collection limb.

The logic is traceability: money that can be followed end to end is money that cannot be laundered invisibly, so the rules build identification and monitoring into every regulated hop. In crypto the obligations attach at the fiat boundaries and the custodial intermediaries: ramps, exchanges, and processors carry the framework wherever they sit in a flow.

What the framework does not do, structurally, is reach non-custodial settlement between self-held wallets, where no intermediary exists to obligate. That is not a loophole so much as an architecture: the traceability burden shifts to the public chain itself, which records every transaction permanently. For a merchant, the practical shape is knowing which of your rails are inside the framework and which are simply public-ledger settlement, and running your own record-keeping to the standard your jurisdiction expects of your business.

AML in practice

A merchant's crypto checkout settles between wallets with no intermediary to obligate, while its card leg and its fiat off-ramps run through providers whose AML programs are their regulated cost of doing business. The merchant's own books reconcile both.

AML on U.CASH

U.CASH's sanctions policy screens wallets and restricted regions, and the fiat rails carry their providers' own programs; the legal pages state what U.CASH does and does not do.

Merchants should map their obligations with counsel rather than assume: taking payment for goods is generally a different activity than exchanging money for others, and the rules follow activities. U.CASH publishes its sanctions screening and restricted-region controls, and the fiat rails carry their providers' programs at their boundaries. On posture: the businesses that navigate this well treat their map as a living document, revisited when rails, jurisdictions, or volumes change, and they write down the reasoning at each revision. The artifact that protects you is rarely a legal opinion alone; it is the record of a business taking its obligations seriously on a schedule.

AML: FAQ

Does taking crypto payments create AML duties for me?
It depends on your jurisdiction and what you do with the funds: taking payment for goods is generally different from exchanging money for others. It is a question for your own counsel; the honest answer is jurisdiction-specific.
What does U.CASH screen?
Wallet screening against sanctions lists and restricted-region controls, stated on the sanctions policy page. Fiat rails add their providers' own programs.
Does accepting crypto create AML duties for my business?
It depends on jurisdiction and what you do with the funds: selling goods differs from exchanging money for others. It is a counsel question, and pretending otherwise in either direction is the actual risk.
What does U.CASH screen?
Wallet screening against sanctions lists and restricted-region controls, stated on the sanctions policy page. Fiat rails add their providers' own programs where they touch the flow.
Are on-chain payments anonymous?
No. They are pseudonymous: every transaction is public and permanent. The chain records more about a payment than any card statement does.
