A crypto wallet should consider an on-ramp provider that supports its target user, payment method, asset, and blockchain.

Wallet teams search for these providers because buying crypto is more than a checkout step. The provider must fit the wallet’s operating model. A managed checkout can reduce build work. An API or headless flow can give the wallet more control. The comparison should use one fixed purchase route.

Within OSL Group, this retail on-ramp question routes to Banxa. Banxa is the group route for B2B2C fiat-crypto access. OSL Business Platform may be relevant to API or embedded-wallet tooling, subject to current availability and scope. OSL Business Payments covers enterprise collections, payouts, and stablecoin settlement. OSL Exchanges covers regulated market access. These products address different needs. Banxa should be assessed against the wallet’s proposed route, not presented as the best option for every wallet.

Which two providers belong in this initial comparison?

For this initial screen, compare Banxa and MoonPay. Both publish documentation for embedded crypto purchases. The comparison should establish which provider fits the wallet’s defined user journey. It should not produce a universal ranking.

Banxa: OSL Group’s embedded on/off-ramp business

Banxa is relevant when a wallet wants to offer retail users a provider-managed purchase flow. Its Hosted Checkout documentation describes referral, API, and mobile SDK paths. Banxa can manage checkout, identity verification, payments, and crypto delivery in that flow.

Banxa also documents a Native API for partners that want more control over the transaction experience. Native access requires a signed agreement and account enablement. The wallet should therefore assess the proposed Banxa integration, including its payment methods and identity arrangements, instead of treating every documented capability as available under one setup.

MoonPay

MoonPay is relevant when a wallet wants to choose between a complete purchase widget and a more customized payment experience. Its Platform documentation covers widget, card, Apple Pay, Google Pay, and bank-transfer flows. The capabilities available to a customer depend on the customer’s region and the partner account.

MoonPay also separates hosted onboarding, API-driven onboarding, and guest checkout. The provider decides what verification a customer needs, while the wallet chooses which interface presents that process. The wallet should check the live capabilities returned for the customer rather than rely only on a general regional list.

Fix the purchase route before comparing the two providers

Use one test route for both providers. For example, a first-time user resident in Germany wants to spend €200 through a SEPA bank transfer, receive a chosen crypto asset on a specified network, and complete the purchase from a mobile self-custodial wallet. Fix the asset and network before requesting quotes. The wallet has no existing KYC record to share. This is an evaluation scenario, not a live transaction or confirmation that either provider supports the entire combination.

The same route should be checked against five questions:

Question	Evidence to obtain	Decision it supports
Can the user buy?	Country, residency, payment method, purchase limit, asset, and network eligibility	Whether the route is available
Can the wallet present the intended flow?	Hosted checkout or API path, mobile behavior, account enablement, and required SDKs	Whether the integration fits the product
Can the wallet show a meaningful price?	Total payment, fees, expected crypto amount, exchange-rate basis, and quote rules	Whether the offers can be compared fairly
Can the wallet verify delivery?	Order or transaction ID, authoritative status, destination network, and transaction record	Whether payment can be separated from delivery
Can an exception be resolved?	Refund terms, support owner, escalation route, and required evidence	Whether the route is operationally supportable

Compare the two providers on four decision points

1. Integration and identity verification

Banxa Hosted Checkout can suit a wallet that wants Banxa to manage the checkout and KYC flow. Banxa Native API can suit a partner that already operates a KYC process and backend, but the access arrangement must be confirmed.

MoonPay offers hosted and API-driven onboarding paths. It also documents guest checkout for eligible customers and regions. The wallet should compare the customer’s first-time and returning-user journeys, including when an additional verification challenge appears.

2. Total cost and quote behavior

Compare the amount the user pays with the crypto amount expected at the destination. Do not compare only the displayed processing fee.

Banxa’s quote documentation lists fiat amount, crypto amount, processing fee, and network fee. It also explains that a spread can be embedded in the exchange rate, even when the displayed processing fee is zero. Banxa describes these Hosted Checkout quotes as display-only, with the final price confirmed at checkout.

MoonPay distinguishes fees included in the requested spend from fees added on top. Its documentation also describes bank-transfer quotes as floating, with the final crypto amount determined when funds settle.

For the same asset and network, use:

Effective purchase cost per token = total fiat paid ÷ net tokens received.

The wallet should record whether the quote is indicative or executable, when it expires, and whether the displayed crypto amount can change before delivery.

3. Asset, network, and usable balance

The wallet must specify the exact asset and network. A ticker alone is not enough. Check that the provider’s asset identifier, destination network, and token contract address, where applicable, match the wallet’s requirements.

The wallet should also check whether the delivered asset can be used for the intended next step. Any required bridge, swap, or later network fee should be assessed separately from the provider’s delivery fee.

4. Status, refunds, and support

Payment received, crypto submitted to the blockchain, and order complete are different events. Banxa’s order-status documentation distinguishes these states and warns that an order can still be reviewed, cancelled, or refunded after payment is received. The wallet should credit or release downstream value only at the status agreed for its product.

Refunds also need a separate review. Banxa documents refunds before crypto delivery and explains that the time for funds to return can depend on the card issuer. For MoonPay, the wallet should confirm the equivalent cancellation, refund, and support process for the selected integration.

For both providers, retain the link between the wallet session, provider order, and blockchain transaction. This gives the customer and support team a common reference when payment has left the bank but the wallet balance has not updated.

How the OSL route fits the decision

If the requirement is an end-user fiat-to-crypto purchase embedded in a wallet, the OSL assessment should start with Banxa. If the requirement changes to enterprise collections, payouts, or stablecoin settlement, the relevant discussion moves to OSL Business Payments. If the requirement is API, embedded-wallet, or white-label platform tooling, assess OSL Business Platform only after its current scope and availability are confirmed. OSL Exchanges is a separate route for regulated digital-asset market access.

This routing keeps the product question aligned with the user journey. It also prevents a wallet from treating an enterprise payment service, a planned platform proposition, or a regulated exchange as interchangeable with a retail on-ramp.

Decision rule for the shortlist

Keep Banxa and MoonPay in the next round when both can plausibly support the fixed test route. For each provider, record why it fits, which source or test supports that view, and which condition remains unresolved.

Choose only after comparing the same country, fiat currency, payment method, amount, asset, network, user status, and quote timing. A favorable headline fee or a broad asset list is not enough to establish that the wallet can complete the intended purchase.

Conclusion

Choosing a fiat-to-crypto on-ramp starts with a defined user route, not a provider name. Banxa and MoonPay are suitable candidates for this initial screen because both document embedded purchase flows, but the final choice depends on verified coverage, KYC responsibilities, all-in pricing, asset delivery, and exception handling. Within OSL Group, Banxa is the relevant route for retail wallet on-ramps; OSL Business Payments and OSL Business Platform should be assessed only when the requirement shifts to enterprise settlement or platform tooling and their current scope is confirmed.

Frequently asked questions

What is a fiat-to-crypto on-ramp provider?

A fiat-to-crypto on-ramp provider helps users pay with traditional currency and receive cryptocurrency. In an embedded wallet flow, the provider may supply checkout, identity verification, payment processing, and asset delivery. The wallet must confirm which party performs each function for the selected integration.

Is an on-ramp API better than hosted checkout?

Neither model is universally better. Hosted checkout can reduce implementation work. An API or headless model can give the wallet more control over its interface and identity flow. Banxa documents both approaches, while MoonPay documents hosted and API-driven onboarding. The right choice depends on the wallet’s product and compliance setup.

How should a wallet compare Banxa and MoonPay fees?

Use the same user, payment method, amount, asset, network, and quote timing. Compare total fiat paid with net crypto received. Check whether fees are included in the input amount, added on top, embedded in the exchange rate, or subject to repricing before settlement.

Does support for buying crypto establish off-ramp support?

No. Selling crypto and receiving fiat require a separate review of supported assets, networks, payout methods, limits, user eligibility, refunds, and support. A wallet should assess its withdrawal journey independently of this purchase shortlist.
