Money Transmitter Rules for Stablecoin Operators

If your product moves stablecoins on behalf of customers, you are very likely engaged in money transmission — and that generally means you need state money-transmitter licenses (and federal MSB registration), or you build on a rail whose operator holds them. The GENIUS Act added a federal payment-stablecoin framework on top of this; it did not replace money-transmission law. Both layers apply, and operators who plan for only one get caught by the other.

This is the licensing question that comes before the yield question. Get it straight first.

Why moving stablecoins is money transmission

Money transmission, broadly, is receiving funds from one party and transmitting them to another. Most stablecoin products do exactly that: a customer sends value, you move it, someone receives it. That activity is regulated at the state level through money-transmitter licenses (MTLs) and at the federal level through registration as a money services business (MSB) with FinCEN, with the anti-money-laundering program that comes with it.

The stablecoin does not change the analysis. If you are moving value for customers, the fact that the value is denominated in a stablecoin does not exempt you. Regulators have been consistent that the activity, not the instrument, drives the obligation.

Two layers, not one

Since the GENIUS Act, stablecoin operators sit under two regimes at once:

Money-transmission / MSB law — governs the act of moving funds. Predates the GENIUS Act and still applies.
The GENIUS Act payment-stablecoin framework — governs the coin itself: who may issue it, its reserves, and the prohibition on the issuer paying interest to holders (§4(a)(11)).

A common mistake is treating the GENIUS Act as the whole rulebook. It is not. It sits on top of money-transmission law. You can be fully aligned with the GENIUS Act’s issuer rules and still be unlicensed as a transmitter — which is its own violation.

The practical paths for operators

There are two realistic ways to be compliant:

Hold the licenses yourself. Obtain MTLs in the states where you operate, register as an MSB, and stand up the AML program. Comprehensive, slow, expensive.
Build on a licensed rail. Use infrastructure whose operator holds the money-transmission licensing, so the regulated activity runs through a supervised entity. You still own your own obligations, but you are not the transmitter of record for the underlying movement.

Movement, the settlement and yield layer for emerging markets, is the second kind of option: settlement runs over rails licensed in the US, Canada, and the EU, so operators building on it are not standing up transmission licensing from zero for the settlement leg. Movement keeps stablecoins as payment instruments and delivers any yield through separate opt-in wrapper and vault products (savUSD, USDCx via Canopy) — so the money-transmission posture and the GENIUS Act yield posture are handled together, not traded off against each other.

Where you still need your own counsel

Building on a licensed rail does not zero out your obligations. Depending on how you hold funds, market to customers, and structure any yield, you may still need your own licenses or registrations, and you will still owe your own AML and consumer-protection duties. Map your specific activity with counsel; do not assume the rail covers everything.

The rail itself: regulated stablecoin rails.
Before launch: the GENIUS Act compliance checklist.
Adding a return: compliant stablecoin yield for fintechs.

Frequently asked questions

Does a stablecoin business need a money-transmitter license? Usually, if it moves stablecoins on behalf of customers. That activity is generally money transmission, requiring state MTLs and federal MSB registration — or building on a rail whose operator holds them.

Did the GENIUS Act replace money-transmission law? No. The GENIUS Act governs the payment stablecoin itself. Money-transmission law governs the act of moving funds. Both apply to a stablecoin operator.

Can I avoid licensing by using a stablecoin instead of dollars? No. Regulators look at the activity, not the instrument. Moving value for customers is money transmission whether it is denominated in dollars or a stablecoin.

If I build on a licensed rail, am I fully covered? No. The rail handles the licensing for the settlement leg, but you still own your own obligations depending on how you hold funds, market, and structure yield. Get your own counsel.

Is this legal advice? No. This is general information. Licensing analysis is fact-specific; consult qualified counsel.
