Feature request: add Electrum compatible BIP39 restore option

[igorglv]

Right now if one wants to restore a wallet from an Electrum mnemonic words, Sparrow shows "Invalid checksum" error. If one imports Electrum wallet directly, Sparrow correctly shows seeds as "Electrum Seed Version System".

Request 1: to add a "Electrum 12 words" menu item in "Mnemonic Words (BIP39)" and may be remove "enter ...", so the menu will looks like "Electrum 12 words" "BIP39 12 words" "BIP39 15 words" "BIP39 18 words" ...

Request 2: add a conversion option from Electrum seeds to BIP39 words in "View Seed..."

For the reasons discussed in #59, I don't want to add Request 1 in Sparrow. Having two seed standards introduces more confusion, and it would do the community a disservice to support creating ESVS seeds. The current support is intended as a restore option for Electrum wallets, but ultimately I believe it is wise to migrate such wallets to a more widely compatible standard.

I don't believe Request 2 is possible, unfortunately.

[igorglv]

I understand the reasoning but it creates absolutely terrible user experience. I knew that the words are correct, so I entered it multiple times, restarted Sparrow and tried again, though that this functionality is currently broken, googled and got nothing, nothing is the help files...
How about to add a warning message for the "12 words" option that Sparrow does not support Electrum seeds (and maybe other well known non standard wallets) and one must import the wallet directly?

[craigraw]

Agreed, this is exactly why two seed standards almost identical in appearance make for bad UX.

I've implemented your suggestion in b9d6cb1.

Sparrow is not able to import the electrum file? Any ideas?

The message in the screenshot contains all the information you need already. Create a new wallet with your BIP39 seed words.

What about the labels? Is there a way to import them from an Electrum BIP39 wallet at least? Electrum allows to export labels in the following format:

{
    "txid1": "label1",
    "txid2": "label2",
}

[craigraw]

Labels from Electrum wallets will be imported with the File > Import Wallet > Electrum feature.

[gus4rs]

Can't see this option in 1.7.3, but I can see "wallet labels", so I need to convert the Electrum export in the BIP format?

[craigraw]

It's 6th on the list.

[gus4rs]

The 6h on the list is "Coldcard multisig" the 7th is "Electrum" but this is to import the full wallet and doesn't work with wallets that are not electrum seed native

[craigraw]

True, that's an Electrum limitation. Your best option is to convert the Electrum labels export to the BIP format.

[gus4rs]

Yep, I converted it and it worked, thanks
