Key takeaways
- Acquirers underwrite the fiat on-ramp and your AML/KYC program, not the blockchain.
- MSB/VASP registration and Travel Rule compliance are baseline expectations.
- Irreversible crypto plus reversible cards makes fraud screening essential.
The heart of how crypto exchanges get approved for payments is your fiat on-ramp: acquirers underwrite the point where a customer funds an account with a card or bank transfer, plus the AML/KYC program behind it. The blockchain side is largely irrelevant to them — it's the reversible card payment buying irreversible crypto that defines the risk.
Registration and Regulatory Status
Before underwriting begins, acquirers expect appropriate registration — MSB (money services business) status in the US, VASP registration or equivalent elsewhere, and state-level licensing where required. Travel Rule compliance for transfers is increasingly expected. Without the right registrations, most acquirers won't engage at all.
AML and KYC Are the Core
Exchanges are inherently attractive to money launderers, so your compliance program is what's really being evaluated:
- KYC and identity verification before funding and withdrawal.
- AML monitoring, including on-chain analytics for suspicious flows.
- Sanctions and PEP screening.
- Transaction limits and source-of-funds checks scaled to volume.
Strong fraud and identity screening is doubly important here because the crypto leaving your platform is irreversible — a fraudulent card deposit that converts to withdrawn crypto is a direct, unrecoverable loss.
MCC Coding on the Fiat Side
Crypto purchases carry specific MCCs, and both Visa and Mastercard have detailed rules for how these transactions are flagged and handled. Miscoding a crypto on-ramp as generic e-commerce is transaction laundering and a fast route to the MATCH/TMF list. Correct coding, done with a crypto-capable acquirer, is non-negotiable.
The Chargeback Problem Is Structural
The card-to-crypto mismatch — reversible payment, irreversible asset — makes chargebacks especially damaging. A buyer can receive crypto, withdraw it, then dispute the card charge. Keeping disputes under the ~0.9% Visa / 1% Mastercard thresholds means aggressive up-front verification, holding periods before withdrawal, and clear terms. The discipline in chargeback management for high-risk merchants is directly relevant.
Reserves and Settlement
New exchange accounts typically carry a rolling reserve reflecting the irreversibility risk and the category's profile. Some exchanges reduce card exposure by leaning on bank rails like ACH for larger deposits, and by settling in stablecoins where it fits their model. Diversifying rails is a legitimate way to manage the chargeback concentration cards create.
Building the Application
Bring your MSB/VASP registrations, your AML/KYC and on-chain monitoring stack, your withdrawal-holding and verification policies, realistic volume, and any processing history. If you're weighing which rails to combine, our broader product overview lays out the options.
No processor can guarantee approval or fixed pricing for a crypto exchange without underwriting your program. What wins approval is proper registration, a serious AML/KYC and fraud program, honest coding, and a credible plan for the structural chargeback risk that card-funded crypto creates.
