Our recent announcement of self-custodial Nostr zaps on our web-wallet brought a lot of attention to Blitz.
But with that came some important questions from the community:
What happens to my Spark wallet if Blitz disappears?
Can I still recover my funds?
We heard you.
That’s why we built
— a fully open-source, reproducible Spark recovery tool.
It works with any Spark wallet. If you have your seed, you can recover your sats — without Blitz, now or in the future.
Trust yourself. Verify the code.

Recover Your Spark Wallet
Use this open-source tool to recover funds from any Spark-compatible Bitcoin and Lightning wallet. Fully stateless. No third-party trust required.
