400% Growth in Swaps, 30% Revenue Gain: Changelly API’s Effect on NGRAVE’s Business

In August 2024, NGRAVE—a Belgian company leading in blockchain security, designing and manufacturing advanced hardware and software solutions—integrated Changelly’s exchange API into its mobile app. Today, less than a year after launch, the swap feature drives consistent revenue growth and supports NGRAVE’s long-term product vision. 

Key Results at a Glance

• Finished Transactions: +400% in 3 months after launch
  
• Revenue Impact: 30% of NGRAVE’s total company revenue
  
• User Activity: +30% increase
  
• Bounce Rate: –15%

From Product Feature to Revenue Driver: 30% of Total Company Revenue

What began as a value-added feature quickly became a business revenue source. Today, 30% of NGRAVE’s total company revenue comes directly from swap transactions powered by the integration with Changelly.

This shows that even in a hardware-centric business, embedded services can drive sustainable growth. With no custodial risk and no off-platform exposure, Changelly’s API-powered swap flow fits seamlessly into NGRAVE’s mission.

Completed Transactions: +400% Growth in 3 Months

In the first quarter after launch, the number of completed swaps per month grew by 400%. This sharp rise signals that users quickly embraced the in-app swap experience, particularly when it was paired with the high-level security they expect from NGRAVE.

For a user base built on caution and long-term holding, such rapid behavioral change underscores a demand for trusted, in-wallet utility.

Driving Engagement: +30% User Activity, –15% Bounce Rate

Since integrating Changelly, NGRAVE has seen a 30% boost in overall user activity. More users are not only opening the app, but staying, engaging with features, and completing meaningful actions.

The bounce rate dropped by 15%, suggesting that users who once opened the app without completing transactions are now finding what they need faster, and staying to act on it. It’s a clear sign that embedded swap functionality has improved the overall user experience, particularly in a security-focused environment where trust is critical.

“Changelly has consistently delivered reliable, timely support for our users. At NGRAVE, our mission is to offer a secure, seamless experience, and Changelly’s swap services have been helping us fulfill that promise.”—Xavier Hendrickx, Co-Founder and CTO NGRAVE

Top assets swapped include BTC, ETH, XRP, and SOL, a mix that reflects the preferences of NGRAVE’s investor-grade user base. These are long-term, high-security users who expect reliability and value.

“A reliable API lets businesses scale without rebuilding the wheel. It’s the fastest way to expand features and grow additional revenue while staying true to core products.” —Zifa Mae, Head of Product at Changelly

Building Together: Co-Marketing in Action

The partnership didn’t stop at integration. Both teams actively promoted the launch through coordinated campaigns.

• NGRAVE reached out to its users with direct emails, social media updates, and a Cointelegraph media campaign. A limited-time 0% fee promo gave early adopters a strong reason to try the new swap feature.
• Meanwhile, Changelly spotlighted the partnership on its blog with over 1.5 million monthly readers, in its newsletter, and across wallet listings. An X (Twitter) giveaway and exclusive hardware discount added extra incentive, and brought both communities together.

This co-marketing synergy helped increase user awareness and drive swap adoption right from launch.

Final Thoughts: A Secure Integration That Delivers

The NGRAVE and Changelly collaboration shows that security and growth can go hand in hand.

By embedding a trusted API that aligns with its mission, NGRAVE delivered more than new functionality—it reshaped how users interact with their wallet. It also created a stable revenue stream, improved engagement, and positioned itself for continued expansion.

This case highlights the long-term value of choosing the right infrastructure partner. When the tech is reliable, the support responsive, and the experience seamless, users respond—not just with trust, but with action.
