Lightning Comes to Cake

Cake Wallet, a privacy-focused multicoin wallet, has launched Lightning Network support for its one million users via the Breez SDK and a custom Spark implementation. Lightning invoices do not embed Spark addresses. Transaction data is not published to public explorers by default. One million users who came for Monero or altcoin management now have peer-to-peer Bitcoin payments with better-than-average privacy defaults in the same interface.

What Semi-Custodial Means in Practice

The implementation is best understood as semi-custodial rather than fully self-custodial. Keys are not in your hands at all times in the way a native Lightning node would be. That distinction matters and Cake is honest about it -- which puts them ahead of most wallet teams who obscure custody trade-offs in marketing language.

Privacy advocate Seth for Privacy has noted that both Ark implementations are evolving fast. Hidden amounts for Spark transfers are still on the roadmap. The current state is: Lightning invoices don't leak your Spark address, and your transaction data stays off public explorers. That is a better privacy baseline than most Lightning wallets ship with.

Why It Matters

One million users just got a Bitcoin Lightning option. The direction is right: Lightning with privacy on by default, no channel management required, no custody surrender to a centralised exchange. Progress, not perfection -- but a million users is signal. The Bitcoin stack keeps expanding the perimeter of who can participate in peer-to-peer electronic cash without giving up sovereignty to do it.
