Wallet of Satoshi x Spark — Self-Custody, Simplified

Wallet of Satoshi has always stood for fast, easy access to Bitcoin — and today, we’re taking the next big step.

We’re excited to announce that Wallet of Satoshi now supports self-custody, powered by Spark.

This marks a major milestone for our team and our users. We’ve worked closely with Spark from the early days, helping shape their SDK and bringing our signature ease-of-use to a fully self-custodial Lightning wallet.

Why self-custody?

Custodial wallets help onboard millions — but for those ready to level up, more control matters. We wanted to give advanced users that option, without losing the simplicity Wallet of Satoshi is known for.

With Spark, we’ve made it possible.

Now in Private Beta

Our self-custody Lightning wallet is now in private beta, designed for users with Lightning experience who are ready to test, explore, and help us refine the experience.

If that’s you, get in touch or reply to our X post to join the waitlist.

We’re especially excited about what this unlocks — including a path to serve U.S. users again, now with a fully self-custodial experience.

What’s next?

This is just the beginning. More features, more access, and more control — coming soon.

If you’re ready to try it out, we’d love to hear from you.
