Fiat-to-Crypto On/Off-Ramp Widget, SDK & API

Overview

Ramp Network provides embeddable fiat-to-crypto (onramp) and crypto-to-fiat (offramp) conversion infrastructure for developers, dApp builders, wallet providers, and Web3 platforms. Partners integrate via a Web SDK, iOS Mobile SDK, or REST API, enabling their end-users to buy and sell 120+ cryptocurrencies directly within the partner application — without leaving the product experience.

The platform operates in 150+ countries across all 50 US states, supporting 40+ fiat currencies and a broad range of payment methods including credit/debit cards, Apple Pay, Google Pay, bank transfers, and regional instant banking (SEPA, ACH, and local rails).

Onramp

Ramp's onramp widget and SDK allow users to purchase 100+ crypto assets across 40+ blockchain networks using local payment methods. The widget is fully embeddable as a hosted checkout or inline widget, configurable with partner branding parameters. Crypto is delivered directly to the end-user's non-custodial wallet; Ramp never holds funds long-term. Integrations can go live within 2 weeks, and eligible partners earn revenue sharing on processed transactions.

Offramp

The offramp product enables users to sell 120+ cryptocurrencies and receive payouts in 30+ fiat currencies via bank transfers, card payouts, and local instant banking methods. It is compatible with MetaMask, Trust Wallet, Ledger, and other self-custodial wallets, as well as custodial exchange accounts, with no exchange account required. Full fee breakdowns and estimated payout times are displayed before transaction confirmation.

REST API

For teams requiring programmatic or server-side integration, Ramp provides a versioned REST API (v1, v2, v3). The API offers access to asset configuration, geolocation and regional availability services, transaction lifecycle events, and webhook notifications for server-to-server status updates. A sandbox testing environment is available for development prior to production deployment.

Compliance & Licensing

All integrations benefit from Ramp's regulatory licenses: FCA (UK), FinCEN (US), CBI (Ireland), and EU MiCAR authorisation — removing the compliance and licensing burden from integration partners.
