Inside the product
Embeddable Widget
Drop a pre-built buy/sell widget into any web or mobile app. Iframe or React component — themed to your brand. Users never leave your product. Handles provider selection, KYC redirect, and payment capture end-to-end.
- iframe + React component options
- Themeable colors, logos, and copy
- Handles KYC and payment capture
- Days to integrate
Smart Provider Routing
Automatically select the optimal provider per transaction based on rate, fees, geography, and payment method. No hard-coded provider logic in your codebase.
Best-Rate Aggregation
Poll every connected provider in parallel and surface the best available rate. Users see one price; you keep provider competition working for them.
Webhook Callbacks
Receive real-time callbacks on order creation, payment received, KYC status, crypto settlement, and failure. Drive your UX from event state, not polling.
Transaction Tracking
End-to-end visibility from fiat payment initiation to on-chain settlement. Query status via API or stream updates over WebSocket.
Fiat Currency Support
Accept 50+ fiat currencies including USD, EUR, GBP, BRL, INR, NGN, TRY, ARS, and more. Local payment rails matched to each currency.
Crypto Asset Coverage
Support for major crypto assets and stablecoins across Ethereum, Solana, Base, Polygon, Arbitrum, Optimism, BNB Chain, and more. New chains added as providers expand.

Operational foundations
Coverage across 180+ countries and 50+ fiat currencies
Provider aggregation broadens launch coverage across connected ramps so teams can compare regional availability instead of designing around a single provider footprint.
- 180+ supported countries
- 50+ fiat currencies (USD, EUR, GBP, BRL, INR, ...)
- Multi-chain crypto output (Ethereum, Solana, Base, Polygon, ...)
- Local payment methods per region
Card and bank rails with provider-dependent settlement timing
Settlement timing depends on provider, geography, payment method, and asset pair. The engine helps teams expose the fastest eligible route instead of forcing every user through the same checkout path.
- Card purchases can settle in seconds when provider and geography support align
- Bank transfers vary by rail, provider, and local payment method
- Real-time transaction status updates
- Webhook callbacks on every state change
KYC handoffs and regional provider controls
Each provider runs its own onboarding and verification flow, while the engine can route users toward providers that fit the regions and payment methods your launch supports.
- Provider-native KYC and AML flows
- Geo-routing to licensed providers
- Shared launch planning around partner, jurisdiction, and payment-method constraints
- Audit trail and transaction reporting
What is a fiat onramp for a crypto app?
A fiat onramp lets buyers move from cards or bank accounts into crypto inside your product, usually through an API or embeddable widget that handles quotes, provider selection, and compliance handoffs.
What is the difference between a fiat onramp and a fiat offramp?
A fiat onramp moves users from cards or bank accounts into crypto, while a fiat offramp sends crypto balances back into fiat payout rails.
Can one integration support both fiat onramp and crypto offramp flows?
Yes. Teams often use one integration layer to orchestrate buy, sell, payout, and settlement visibility while routing each flow to the provider that best fits the user, geography, and payment method.
How do KYC and compliance work in a multi-provider onramp setup?
Each provider runs its own onboarding and verification flow, and routing can steer users toward providers that support the relevant region and payment method.
Which payment methods can a fiat onramp integration support?
Teams commonly combine card payments, bank transfers, and local payment rails based on the providers and regions included in the launch.
