https://github.com/FarCanary/ElectrumSeedTesterI 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.
