Can You recommend some solution for iOS which can use already used keys for Electrum wallet? I mean use same common funds parallel on desktop and on my smartphone.

I'm not aware of any wallets that supports Electrum's seed...

But If you don't mind changing the wallet, you can try GreenAddress. I think it's the only (excluding Bither because it's unstable) open source wallet that supports both iOS and Desktop.

You have other options like Exodus, Coinomi and Blockchain.com but, I wouldn't recommend using them unless you're storing small amounts.

GreenAddress was actually renamed to Green: Bitcoin Wallet (https://apps.apple.com/us/app/green-bitcoin-wallet/id1402243590) for mobile devices. I have tried the mobile version and it worked fine on Android. @zxbit, if you create a new wallet in Green Wallet then you will be able to use your new recovery phrase (the seed) in most wallets, including Electrum. This way you can recreate your Green Wallet addresses in Electrum on the desktop

Edit: Use a different wallet than GreenAddress.

While there is no other wallet which supports importing Electrum's seed phrase format, BlueWallet for iOS is open source and allows you to import individual private keys. I'm not sure if it also supports importing master private keys, but it does support importing master public keys. You could import the keys from Electrum to BlueWallet to have the same addresses accessible from both desktop and phone.

I would suggest that if you are storing the bulk of your funds on Electrum on a desktop computer, then you don't import the private keys to a mobile device for the sake of the security of your funds. If you lose your phone, there is a good chance you lose all your coins too. You could instead safely import the master public key to create a watch only wallet your phone, and transfer a small amount of funds to addresses generated by BlueWallet which you can spend from your phone.

I know one of IOS Bitcoin wallet which is Bread wallet(BRD wallet) that you can use on Electrum and BRD wallet but the only problem is if you created the wallet from Electrum you can't import it to BRD wallet.

However, you can use the seed generated from BRD wallet to Electrum. This is the only thing that I think you can use at the same time on different wallets. What you need is make a wallet first in BRD wallet and import the seed phrase from BRD wallet to Electrum.

The guide can be found from here below
- Recover BRD Wallet (BreadWallet) in Electrum (https://bitcointalk.org/index.php?topic=5204223.0)

If your wallet is already created on Electrum you can't able to use the seed to BRD so, my suggestion is to transfer your funds from Electrum to BRD wallet and then use the seed phrase from BRD wallet to Electrum if you want to use them on both Desktop and IOS device.

if you couldn't find any ios wallets that could support Electrum seeds or import the extended private/public key[1] and if you trust the ios wallet then you can do it in reverse. meaning create the seed with your ios wallet then import that in your desktop Electrum wallet since Electrum desktop has a lot more features and supports everything including the extended keys.

[1] the extended public key is for when you want to create a watch only wallet and extended private key obviously imports every private key. in Electrum xpub can be found under Wallet (menu) > Information and xprv is by typing getmasterprivate() in console tab.
keep in mind that you have to be extremely careful about what you do. importing the same key in multiple places increases the risk of losing your money.

Are you tried this? AFAIK Green Wallet is multisig wallet, so I doubt.

My bad, the desktop version is multi signature and can only be recovered using this tool: https://github.com/greenaddress/garecovery

However, the method mentioned by BitCryptex should work just fine. Both iOS and Android version generate a standard (BIP39) wallet.

I don't think so. These versions are multisig-wallets 2/2 too. You only have one BIP39 seed, and you need two to recover.

Actually, you're right. I was quite sure that I could use Green Wallet while being offline and generate native SegWit addresses, but I have just double checked that and I am wrong. Normally, I would have recommended Samourai Wallet (https://samouraiwallet.com/), but it hasn't been released for iOS, yet.

You can in bluewallet (https://bluewallet.io), it supports electrum seeds

I'm curious, can you tell me how to import Electrum seeds to blue wallet?
Because last time I tried (which was a minute ago :D), it didn't worked for both legacy and segwit Electrum seeds.

BTW, the article (http://help.bluewallet.io/en/articles/2847190-how-to-backup-export-and-import-your-wallet) in their FAQ (which is incomplete) is talking about importing blue wallet seed (BIP39) to Electrum, not vice versa.

AFAIK there is no wallet which supports the electrum mnemonic code (except for electrum obviously).



Since most wallets (basically all except for electrum) use BIP39, this is also supported by electrum when importing a wallet.
When creating a wallet in electrum it however uses its own way to create a mnemonic / derive the keys. So electrum mnemonics are only usable within electrum.

No, BlueWallet supports importing Electrum seeds. But an imported wallet cannot be empty.

Well spotted. Support for importing Electrum SegWit seeds has just been added in the latest version.

https://github.com/BlueWallet/BlueWallet/releases

You can use Electrum seed on blockchain.com and together with their IOS app its probably what you need.

No, you can't.

Blockchain.com is a (shitty) web wallet and does not support the use of electrum mneominc codes.
Besides that, a lot of useful features are missing.

I wouldn't recommend blockchain.com (or any other web wallet) to anyone.
