Just tried to do the same thing: import private key from my blockchain.info wallet into my omniwallet but got this message: Must be a valid Bitcoin private key
I’ve tried using the Hex and Base64 formats which are the only two formats common to both Blochain.info and Omniwallet, both formats produce the same message as above.
I’m copy/pasting into the ‘Import a BTC/MSC Private Key’ field of my omniwallet all the information from my blockchain.info wallet that appears in the field for the Hex format and then for the Base64 format.
There’s a message above the fields for the different formats which reads: Export Unencrypted Below are your private keys in JSON format…
However there’s no download or copy button; instead the only option is to highlight the info and copy it.
Clearly however I must be doing something wrong.
Thanks in advance for any help
