Electrum Seed Tester.

I made a tool to check my Electrum cold wallet is creating the correct addresses. I thought I would make it available to everyone. It's based on Ian Colemans awesome BIP39 tool. It works with Bech32 and legacy seeds, it does a proper electrum checksum, and shows the correct addresses based on the type encoded in the seed. Its a git fork of the BIP39 tool so it should be very easy for people to check what I have changed.

Obviously don't type your real seed into a computer connected to the Internet.

Fantastic work! This will be of great use to the Electrum community... especially for the folks who for whatever reason, don't or can't run Electrum, but need to "rescue" coins contained within Electrum seeds... and also for the people who always ask "What happens if Electrum disappears?"


I had started something similar... but never got around to actually implementing the checksum stuff. I took the lazy option and simply ignored the checksum calculations!

Thanks! It would be great if the tool also worked with a custom wordlist.
