Re: Ian Coleman BIP39 / Derive P2SH addresses from Electrum generated Seed

Quote from: Pffrt on Today at 01:33:00 PM

To generate p2sh-segwit, you can follow the simple trick with Electrum.
1. Install Electrum.
2. Generate Seed.
3. When you verify seed, click on option and mark the box with bip39
4. It will warn you as not valid but will allow you to proceed.
5. Enjoy p2sh-segwit.

I'm aware of the steps to generate p2sh-segwit with Electrum (see second picture).

I'll try to rephrase my question/explain what I am trying:

I've Generated p2sh-segwit wallet with Electrum.
Got a Seed, got addresses.
Now I want Ians tool to show me the same addresses Electrum dervied from that seed.

[Why am I trying to do this? If the tool is able to derive the correct addresses (Like it normaly does with other address types and the correct settings) I am able to automatically bruteforce the 1-2 missing/wrong written words from a slightly incorrect remembered 12 word seed. But to do this I first need to make sure that Ians Tool and Electrum are deriving the same addresses to a correct seed (the one I created with Electrum just for testing purposes) or the brute force won't work. The address derivation from seed works well with other seed / address types, but I haven't figured out the settings/code changes to make it work with p2sh-segwit addresses.]
