Fiat On-Ramps
Fiat on-ramp providers enable you to buy Sui-native tokens (SUI, WAL, DEEP, and others) using fiat currency from a user's bank account, card, or payment method. Embedding an on-ramp provider into your app allows users to fund their Sui wallets with traditional currency without leaving your interface. Verify current provider capabilities before integrating.
Multiple third-party providers support Sui on-ramp integration, including Banxa, Stripe, Coinbase, Meld, and Onramper. Each provider differs in supported assets, regional availability, and integration method. Choose a provider based on the assets your app requires, the regions your users are in, and whether you need a hosted widget or a direct API.

How do I choose an on-ramp provider?
Selecting a provider depends on three factors. Also consider KYC handling: some providers handle KYC entirely within their hosted flow; others require you to collect and pass user data, so understand your compliance obligations before integrating.
- Asset support: Confirm the provider supports the specific token your app requires. SUI is broadly supported, but tokens like WAL, DEEP, CETUS, and NAVI are available through fewer providers.
- Regional availability: Most providers restrict service in certain countries due to regulatory requirements. Check the provider's coverage map before committing to an integration.
- Integration method: Providers offer different integration surfaces. Some offer hosted checkout widgets you embed with a URL or iframe. Others offer REST APIs you call server-side. Choose based on how much control you need over the user experience.
How do I integrate an on-ramp provider into a Sui app?
Most providers support a hosted widget approach:
- Construct a URL with query parameters that pre-fill the user's wallet address, preferred asset, and source currency.
- The user completes the purchase inside the provider's interface.
- The provider delivers tokens directly to the wallet address you supplied.
The specific parameters, authentication method, and webhook events differ by provider, so review the provider's documentation before building.
