The European neobank enables access to Bitcoin self-custody: fast transfers, low fees, and offline payments without managing nodes.
Deblock, a neobank founded in 2024 and led by former executives from Revolut and Ledger, has successfully integrated Bitcoin technology into its platform, reaching a user base of 300,000 clients. This innovation was made possible through the implementation of the Breez SDK with Spark technology.
The solution implemented by Deblock marks a further step forward in making self-custody more accessible. The integration provides near-instant transfers, negligible fees, built-in self-custody, offline payments, and speeds comparable to the Lightning Network, while eliminating the need for users to manage payment channels or routing nodes.
Jean Meyer, CEO of Deblock, stated:
“With this integration, we can finally deliver both: buy or sell bitcoin in seconds, and it’s yours the moment you do.”
The Breez SDK implementation brings four key benefits to users:
- speed: Bitcoin transfers become effectively instantaneous thanks to the Spark implementation;
- economies of scale: fees are so low that even microtransactions are feasible. Users can use bitcoin for everyday payments;
- financial sovereignty: Breez SDK keeps funds under the direct control of their owners. This expands peer-to-peer use while minimizing the app’s regulatory footprint;
- ease of use: users gain the speed and robustness of the Lightning Network without dealing with the technical complexity of payment channels. Features like offline payments are natively integrated, along with instant settlement and nearly zero counterparty risk.
The benefits of the Breez SDK, available to Deblock users, are also accessible to other services, such as remittance apps, payroll platforms, and applications that already integrate on/off ramp functionality for Bitcoin.
