Overview

Nexaflex a crypto SaaS product for crypto payments/ticketing and a rechargeable vape system with customizable settings.

The Problem

Nexaflex identified a critical gap in the crypto ecosystem:
• Users could buy, hold, and trade crypto, but spending it globally was complex and restricted.
• Conversion to fiat required multiple steps and was not seamless at point-of-sale.
• Existing solutions lacked compliance, global reach, and everyday usability.

Nexaflex’s Vision:
A Crypto-Visa SaaS platform that empowers users to spend crypto anywhere, anytime — just like traditional money.

Our Solution

We delivered a Software-as-a-Service (SaaS) platform that powers Nexaflex’s global crypto payments ecosystem.

Core Features Delivered:
• Crypto-Visa Card System — instant virtual card issuance.
• Global Spending — crypto-to-fiat conversion in real time at any Visa merchant.
• Compliance by Design — KYC/AML checks embedded into onboarding and transactions.
• Unified Experience — SaaS web + mobile apps for wallets, cards, bill payments, and ticketing.
• Fraud Detection — transaction monitoring, anomaly detection, and dispute management.
