CryptoSwift - Crypto-to-Fiat Gateway & POS System

Client & Context

CryptoSwift is a fintech startup aiming to simplify crypto payments for merchants. The goal: develop a fast and compliant crypto-to-fiat off-ramp solution, enabling seamless transactions at physical points of sale and online — with a 12-minute payout guarantee.

Idea

Crypto payments were gaining traction, but most off-ramp solutions were unreliable, slow, or not compliant. The team envisioned a platform that could combine stablecoin payments with automated fiat settlements, while protecting merchants from market volatility.

Design & Development

We started with deep market research and coordinated closely with legal advisors to ensure the product met compliance in various jurisdictions.

Key work included:

• Writing a detailed product requirements spec
• Designing a user-friendly interface for merchants
• Building the backend in Python with real-time core-banking integrations
• Creating a React frontend optimized for speed and responsiveness

Launch & Impact

The product launched successfully with the following milestones:

• Crypto-to-fiat conversion in under 12 minutes
• 100% price guarantee on every transaction
• Live deployments with early adopters

Business Benefits

• Allowed merchants to accept crypto without exposure to volatility
