Blockstream Acquires Elysium Lab, Opens Swiss HQ
Blockstream has acquired Elysium Lab, a Lugano-based startup focused on keyless Bitcoin wallets and Lightning infrastructure. The deal was announced on July 21, 2025. While the valuation wasn’t disclosed, the acquisition serves as the launchpad for Blockstream’s new European HQ, Blockstream CH SAGL, in Switzerland.
Elysium built a wallet that supports Bitcoin, Lightning, Blockstream’s Liquid sidechain, and stablecoins. Their standout feature is a patent-pending keyless authentication SDK called KARE, designed to eliminate seed phrases without compromising user control. This product has seen adoption in over 30 countries and fits well with Blockstream’s goal of expanding usability for Bitcoin infrastructure.
This move echoes past acquisitions by Blockstream, like GreenAddress (which became Blockstream Green) and Spondoolies (for mining hardware). Now with Elysium, they’re bolstering the user-facing layer which complements their Lightning, Liquid, and hardware wallet stack.
Strategically, this places Blockstream deeper into Switzerland’s fintech landscape. Lugano has become a hub for Bitcoin activity through the Plan ₿ initiative, and this deal anchors Blockstream in that ecosystem. The new Swiss HQ will also serve as an incubator for Bitcoin-native startups, offering CHF 100,000 grants for those building on their tech.
We’re seeing more of these quiet but high-impact M&A moves in crypto. After a slower 2022 and 2023, 2024 saw over 240 crypto M&A deals, and 2025 is shaping up to keep pace. Large, well-funded companies are acquiring niche innovators to accelerate their product roadmap, absorb talent, and gain jurisdictional presence. With Elysium, Blockstream checks all three boxes.
From an M&A perspective, this is a solid example of accretive expansion: acquiring a strategic team, integrating patented tech into an existing stack, and reinforcing regional footprint in a regulatory-friendly environment.
As crypto matures, we’ll likely see more of these “infrastructure stack” consolidations, where the backend, protocol, and UX layers converge under one roof.
