Klever: Lightning-Fast Bitcoin Made Simple
Klever is a popular non-custodial crypto app following a single product principle: simplifying crypto for everyone. The principle has attracted over 100,000 monthly active users holding their own keys across multiple chains and multiple assets, all in one app.
Klever has always seen bitcoin as part of everyday life, not just an asset to HODL, but something their users can send and spend naturally in their everyday lives. Klever already supported on-chain bitcoin, but on-chain doesn't keep up with everyday use because of long delays, high fees, and an experience out of step with the rest of what they were building. Klever users needed something faster, and the team knew it had to deliver without compromising on custody or simplicity.
Klever had been looking for faster bitcoin for years. Lightning was the obvious answer. But every non-custodial Lightning path on the market exposed users to the underlying infrastructure: channels to open, liquidity to manage, and infrastructure headaches. None of that is designed for an all-purpose, everyday app.
The alternatives were even worse. Custodial Lightning providers solved the UX problem by removing custody, which was a non-starter. Wrapped bitcoin on other networks solved the speed problem by removing the bitcoin, which introduced a different trust model and a different value proposition entirely. None of the available options satisfied the brief: real bitcoin, fast settlement, users control their keys, and an intuitive experience with no homework.
Sitting on the sidelines was not an option either. Klever's long-term vision is to create an app where users move frictionlessly between bitcoin and other assets without thinking about the underlying chains. Without bitcoin playing its part, that vision stops at the starting line.
Klever integrated the Breez SDK to bring Lightning-fast, non-custodial bitcoin into the wallet. Users can now send and receive bitcoin directly, and the SDK even powers Klever's internal swap engine between bitcoin and the other assets they support.
For users:
- Speed: sending and receiving bitcoin Lightning-fast, with minimal fees.
- Economy: small payments and routine transfers are finally viable inside a wallet that keeps users in full control of their keys.
- Control: Klever users move bitcoin without relinquishing custody, and they can swap bitcoin with assets on other networks without leaving the app.
"If you want to bring bitcoin into real world usage with speed, simplicity, and self-custody, Breez gives you the foundation to do it right while you focus on building a great product."

For developers:
With the Breez SDK, Klever shipped Lightning-fast bitcoin across Android, iOS, and their swap engine. There are no nodes to run, no channels to open, and no liquidity to manage. Klever's team was free to focus on user experience and product design, not the technicalities of Lightning infrastructure.
For growth:
Bitcoin is now part of how users use Klever every day. Sending, receiving, and swapping bitcoin and other assets are all built seamlessly into the app, with usage growing consistently since launch. Klever can even run as a bitcoin-only wallet, with a dedicated journey inside the app for users who just want BTC.
The Klever app itself is now close to achieving its vision: a single, non-custodial interface where bitcoin moves instantly, swaps clear across chains, and the underlying mechanics stay out of view. Bitcoin was the holdout, and now it's the foundation. With the Breez SDK, Klever works the way it was always meant to.
