How We Enabled Seamless Crypto Off-Ramps Inside Ledger Live

Selling crypto should be as simple as buying it.
But for millions of users inside Ledger Live, that experience didn’t exist natively. MoonPay, one of the leading fiat on/off-ramp providers, partnered with Boosty Labs to change that — enabling users to sell crypto directly from Ledger Live, without friction, complexity, or security trade-offs.Behind this seemingly simple experience was a complex integration challenge: connecting two large-scale systems with different architectures into one seamless user journey.

Here’s how we did it

The Challenge

Ledger Live and MoonPay operate as independent ecosystems — each with its own infrastructure, APIs, and product logic. To deliver a smooth off-ramp experience, we had to solve several critical challenges:

Our Solution

Boosty Labs designed and built a dedicated middleware platform that acts as the invisible engine behind the integration — ensuring everything works smoothly, securely, and at scale.

Seamless integration layer between Ledger Live and MoonPay
Built a custom API bridge that handles all communication, translating data between systems in real time
Smooth and intuitive sell flow for end users
Enabled users to off-ramp crypto directly within Ledger Live — without leaving the app
High-performance, scalable architecture
Designed a multi-layer system (processing, caching, compute, monitoring) to handle production-level load
Full observability and reliability
Implemented logging, monitoring, and error-handling mechanisms to ensure stable performance
End-to-end testing and validation
Delivered a fully tested integration, covering functional, load, and security scenarios
Comprehensive documentation for long-term scalability
Equipped Ledger teams with everything needed to maintain and extend the integration
