Crypto businesses — exchanges, on/off-ramps, OTC desks, Web3 wallets, and NFT marketplaces — face a payments paradox: they move enormous volume, yet almost no acquirer wants to underwrite the fiat card on-ramp. Solving that on-ramp is the single hardest piece of building a compliant crypto business.
Why crypto is high-risk to an acquirer
The card schemes treat crypto purchases as quasi-cash under MCC 6051, which carries elevated fraud, regulatory, and chargeback exposure. Most US acquirers decline the category outright. The ones that engage price in the risk and demand a full compliance stack before they will even open a file.
Licensing and AML decide approval
Card acceptance for crypto hinges on your regulatory posture: FinCEN MSB registration plus state money-transmitter licenses in the US (or a licensed EMI/BIN sponsor in the EU), robust KYC/AML, FATF Travel Rule compliance, and OFAC/sanctions screening. Without that stack, no acquirer will quote — your trading volume is irrelevant until the licensing is in place.
"In crypto, your money-transmitter licensing and AML stack — not your trading volume — decide whether you can accept cards."
Domestic, offshore, and multi-rail reality
Domestic card on-ramps exist but are reserved for licensed, well-capitalized exchanges. Most crypto businesses route fiat card volume through offshore acquirers and EU EMIs, and lean on ACH, wire, open banking, and stablecoin rails alongside cards. A multi-rail architecture is the norm, not the exception — single-rail crypto businesses are one freeze away from going dark.
Chargebacks and reserves
Crypto chargebacks are unforgiving: because on-chain delivery is irreversible, a "goods not received" or "fraud — card not present" dispute is a direct loss, not a reversible one. Expect rolling reserves of 5–10% or higher held for 90–180 days. The levers that bring them down are 3-D Secure 2 on every card flow, strong KYC, and on-chain proof of delivery (the settlement transaction hash).
What underwriters require
- FinCEN MSB registration + state money-transmitter licenses (or a licensed sponsor/EMI)
- KYC/AML program, FATF Travel Rule compliance, and OFAC/sanctions screening
- 3-D Secure 2 on all card transactions
- On-chain proof of delivery for dispute defense
- Audited financials and demonstrated capital
- Clear refund, withdrawal, and AML/KYC terms on-site
The win is matching your license footprint and target geographies to an acquirer with explicit crypto appetite — not applying blindly and burning approvals. That placement work is what we do for exchanges, on/off-ramps, OTC desks, and Web3 marketplaces.
