Cake Wallet Brings Self-Custodial Lightning to Over 1 Million Users with Spark
Cake Wallet adds Lightning Network support via the Breez SDK, built on Spark infrastructure, delivering instant self-custodial Lightning payments to over 1 million users.
Lightning has always forced wallets into a tradeoff: give users self-custody and deal with channels, liquidity, and always-online requirements. Or go custodial and pretend the problem doesn't exist.
Cake Wallet refused to pick either. They waited. Specifically, they waited until a solution existed that didn't compromise on sovereignty, privacy, or self-custody. That solution is Spark.
Today, Cake Wallet is adding Lightning Network support via the Breez SDK, built on Spark infrastructure. Their users get instant Lightning payments with full self-custody, no channel management, and no need to be online to receive funds.
Why This Matters
Cake Wallet is one of the most respected privacy-focused wallets in Bitcoin. They support Monero, Bitcoin, Litecoin, and more across iOS, Android, macOS, and Linux. Bootstrapped. Open-source. Over 1 million users and 1 million downloads.
They didn't add Lightning for years because nothing met their standard. Traditional Lightning requires users to manage channels, pre-fund liquidity, and keep their device online.
Spark changes the equation. With a trust-minimized distributed operator model, users stay in control of their funds at all times. On-chain exit is always available. And critically for Cake's users: Spark addresses are never broadcast in Lightning invoices, and transactions are never published to any public ledger.
How It Works
Cake Wallet integrates through the Breez SDK, which is built on Spark's infrastructure. For developers, the Breez SDK handles the complexity: Lightning compatibility, mobile notifications, and support across major frameworks and languages.
For users, none of that matters. They open Cake Wallet, send or receive over Lightning, and everything just works. Self-custodial by default. Private by design.
