I think you can import your wallet from block.io since your wallet is multisig wallet this is one of the hardest thing to recover because if you use the mnemonic seed BIP39 to electrum in standard wallet you can recover only the p2pkh address first symbol(1) but the p2sh address start symbol(3) not included..
But if you really wanted to recover it to your electrum wallet the only thing that i know is to recover and import it into electrum using mnemonic seed that you got from block.io..
But this part is hard because you need to use some tools online but i don't know if its safe there are many members here recommend this tool but i really don't know if its safe or not you can try it in your own risk..
Or you have to manually or otherwise extract the private keys from your MultiBit HD wallet/seed...
Automated (but technical) method requiring use of python scripts:
https://github.com/HardCorePawn/multibit_recoveryManual method:
- Create offline version of
https://iancoleman.github.io/bip39/- Put in your MultiBit HD seed
- Set Derivation Path -> BIP32
- Set Client = "MultiBit HD"
- Copy all the address/private keys (click show more until you are sure you have more than all the addresses you ever used)
- Set Client = "Custom" -> Set Derivation Path = m/0'/1
- Copy all the change addresses/private keys (click show more until you are sure you have more than all the addresses you ever used)
Once you have all your private keys:
- In Electrum -> New/Restore -> Standard Wallet -> Create a new seed
- Once wallet is created, "Wallet -> Private Keys -> Sweep"
- Paste in all the private keys you got from automated or manual method
You should now have all your coins in an Electrum HD Wallet.
You can only get the private key which is p2pkh addresses that include you bitcoins just skip the multibit hd from the method ..
Why you honestly wanted to import your wallet from block.io? i saw your thread that you wanted to redeem or get your bitcoin gold ..
Note: to do this better to transfer your bitcoin instead to segwit address in electrum it should be a good choice and more advantage than the legacy wallet..
