Crypto On & Off Ramp API

Rampable's flagship B2B product is its On & Off Ramp API, which enables developers and platforms to embed crypto-to-fiat and fiat-to-crypto conversion directly into their applications. Integration is available via webview or direct REST API, making it flexible for both mobile and web platforms.

Product Overview

Rampable abstracts the complexity of multi-country banking integrations, compliance, and crypto network bridging into a single API. With free API integration, transparent percentage-based fees (starting at 0.3%), and coverage across Southeast Asia, South Asia, Europe, and the United States, it is particularly well-suited for Web3 startups and platforms targeting emerging markets alongside global stablecoin users.

Key Features

• On-ramp: Allow users to purchase cryptocurrencies (USDT, USDC, DAI) using fiat currencies (USD, EUR, GBP, INR, JPY)
• Off-ramp: Convert user crypto holdings to fiat and deliver to bank accounts within 5–20 minutes
• Webview integration: Embed the Rampable UI in your app without building conversion flows from scratch
• Webhook integration: Receive real-time event notifications for transaction status changes
• Sandbox environment: Full test environment for development and QA workflows
• API key management: Separate public/private credentials managed via the Rampable business dashboard
• Custom Token Listing: Private buy/sell mechanisms for specific tokens, including custom smart contract development

Supported Assets & Networks

Supported stablecoins include USDT on Polygon and Tron, USDC on Stellar, DAI, and FANC. Off-ramp is available for Indonesia, Singapore, India, Malaysia, Europe, and the United States.

Use Cases

Rampable serves fintech platforms, DeFi projects, and Web3 applications seeking to add fiat on/off ramp capabilities without building the infrastructure from scratch. Its B2B-first architecture with separate authentication flows makes it ideal for platforms serving both business clients and end users.
