  1. Use Case

On/Off Ramp

The On/Off Ramp API suite enables seamless conversion between cryptocurrencies and fiat currencies, supporting end-to-end deposit, withdrawal and trading flows. It allows corporate clients to manage withdrawal destinations via adding bank accounts, cards or crypto wallet addresses, perform buy/sell transactions, retrieve live quotations, and monitor transaction statuses in real time. The APIs are designed for PSPs, fintechs, e-commerce platforms, and other KYB-approved corporate clients to embed compliant crypto-fiat services into their own applications.

Scope of Services#

Our On/Off Ramp APIs support:
Quotation Services
Retrieve real-time price quotations for buy/sell transactions
Cryptocurrency Withdrawal
Withdraw cryptocurrencies to added crypto wallet addresses.
Buy Crypto
Convert fiat to supported cryptocurrencies at competitive rates.
Sell Crypto
Liquidate crypto holdings into fiat currency & transfer to different beneficiaries, such as bank accounts and cards.
Bank Account Management
Add, list, and remove whitelisted bank accounts.
Card Management
Add a card for future withdrawals, list available cards, and remove linked cards.
Transaction Status Tracking
Check real-time status of on/off ramp transactions.
