In 2020, Ballet—a U.S.-based provider of secure, user-friendly cold storage solutions—partnered with Changelly to integrate in-app cryptocurrency exchange functionality directly within its mobile companion application. By embedding Changelly’s cryptocurrency exchange API, Ballet users gained seamless access to thousands of trading pairs—all within a secure, non-custodial environment.
This strategic integration has yielded impressive results over the past five years: transaction volume in the Ballet app has doubled, monthly active users (MAU) have grown by 21%, and the average order value (AOV) has surged by 166%. Today, 40% of all swap transactions initiated in the Ballet app are powered by Changelly, underscoring both the reliability of the service and the trust users place in it.
By simplifying in-wallet exchange processes through Changelly’s API, Ballet has significantly boosted key performance metrics and revenue. This integration allows one of the market’s leading cold storage solutions to deliver a practical trading experience—without compromising on self-custody, security, or ease of use.
X2 Transaction Volume Post-Integration
Since integrating Changelly’s exchange API, Ballet has observed a 100% increase in transaction volume within its application. This surge reflects heightened user engagement, stronger transaction intent, and an overall more functional product experience.
Rather than requiring users to move funds to centralized exchanges—a process that introduces complexity and security risks—Ballet now enables value exchange directly within the wallet interface. This bridges the gap between asset storage and asset utility, creating a smoother, more intuitive journey for users.
"Changelly supports thousands of trading pairs, meeting the needs of most Ballet users. Their trading service is fast, stable, and backed by a professional compliance team, ensuring secure transactions."
— Bobby Lee, CEO of Ballet
The ability to swap assets instantly without leaving the app removes friction and encourages more frequent use. As a result, users are not just storing crypto—they’re actively managing and utilizing it.

Average Order Value Up 166%
One of the most striking outcomes of the integration has been the 166% increase in weekly average order value (AOV). This growth was driven by increasing user confidence in the in-app exchange experience, particularly during the early stages following the API rollout.
While AOV growth has stabilized in recent months, it remains at historically high levels. In the context of a security-first cold storage product, this sustained elevation indicates lasting trust and continued active participation from users.
Higher AOV suggests that users aren’t just making small test swaps—they’re conducting meaningful transactions, often involving larger amounts of cryptocurrency. This shift reflects a deeper level of engagement and trust in both Ballet’s platform and Changelly’s underlying exchange infrastructure.
40% of Swaps Now Powered by Changelly
Currently, 4 out of every 10 swap transactions initiated in the Ballet app are executed via the Changelly API. This widespread adoption highlights the service’s reliability and its strong appeal among end users.
Ballet users consistently choose Changelly due to its:
- Low-latency execution
- Competitive pricing
- Regulatory transparency
These factors combine to create a trustworthy, efficient swapping experience that aligns with Ballet’s core values of security and simplicity.
"Ballet has built a unique and accessible cold storage solution, and we’re proud to enhance that experience with seamless, reliable in-app exchanges. The success of this partnership lies in our long-term alignment on product values, user expectations, and execution. The growth we’ve seen together proves that secure self-custody and active user engagement can go hand in hand."

This hybrid approach empowers users to:
- Store assets securely offline
- Swap coins instantly when needed
