Crypto-Fiat On/Off-Ramp API & Infrastructure

Quppy's B2B API delivers white-label crypto-fiat conversion infrastructure for fintech platforms, e-wallet providers, and businesses requiring integrated on/off-ramp capabilities.

Product Overview

The API supports three core transaction flows: buying crypto (fiat EUR transferred via virtual IBAN is converted and credited to custodial wallets), selling crypto (crypto deposits are exchanged and settled to fiat IBANs), and direct currency conversion (crypto-to-crypto and fiat-to-crypto swaps) — all with immediate settlement and zero volatility risk for the operator. Backed by 5+ years of processing history and a regulated partner network, Quppy enables businesses to launch compliant crypto-fiat products without building from scratch.
