Blockstream, the global leader in Bitcoin infrastructure technology, has announced a collaboration with Swiss Bitcoin-only startup Relai which, from today, will be integrating Blockstream’s “Lightning-as-a-Service” solution Greenlight into its popular self-custody wallet. The strategic move represents a significant milestone in the evolution of Relai, Greenlight and the Lightning Network set to bring fast, low-cost Bitcoin payments to over 100,000 Relai users throughout Europe. 

Launched last year, Greenlight has redefined the integration of Lightning payments for developers and enterprises worldwide, offering a balance between the convenience of custodial solutions with the security of their non-custodial counterparts. By leveraging Greenlight, Relai’s users across Europe can now enjoy the benefits of the Lightning Network 

directly via their wallets, enabling them to send and receive Bitcoin faster and more conveniently than ever before. 

“We’re delighted that Relai has chosen Blockstream’s state-of-the-art Greenlight service as its go-to for integrating seamless Lightning payments within its popular wallet,” said Christian Decker, Core Tech Engineer and Greenlight lead at Blockstream, emphasizing the importance of the development. “Relai’s integration of Greenlight not only adds another layer of functionality to the Relai app, but also aligns perfectly with Blockstream’s mission to foster Bitcoin adoption on a global scale.” 

“Relai is proud to have collaborated with Blockstream on the integration of its “Lightning-as-a-Service” solution, Greenlight, bringing ‘Lightning-fast’ Bitcoin payments to our more than 100,000 users throughout Europe,” said Julian Liniger, CEO of Relai. “Bitcoin is sound money. Lightning is the future of Bitcoin. It’s how money will be moved around the world in the 21st century. That’s why Lightning is a strategic focus of Relai and will be integral to our mission of bringing BTC to millions of people quickly, easily, and securely!”

Blockstream’s Greenlight: The Hassle-Free Solution for Integrating Bitcoin Lightning Payments 

Since its launch last year, Greenlight is rapidly emerging as the go-to service for developers and enterprises around the world looking for a hassle-free solution to integrating fast, inexpensive Bitcoin payments. Prior to Greenlight, the complexities of incorporating Lightning node functionality within apps had long been a barrier to the growth of the Lightning network itself, often requiring endless hours of work on the part of developers. 

Greenlight makes that process easier than ever before. Greenlight’s unique architecture ensures that private keys are stored always by the user and are, at no point, shared with Blockstream or any other third-party. For app developers, this reduces the risk and liability associated with holding user funds, but also provides users with the additional benefit of exclusive and full control over their funds. 

For businesses building on Lightning, Greenlight alleviates the challenges developers face in building and maintaining Lightning infrastructure. By offloading these complexities to Blockstream, companies can focus on creating innovative applications on the Lightning Network without compromising on security or functionality, all while avoiding costly solutions, freeing up valuable time for innovation.
