So, I participated in an ICO a while back, and to send the ETH over to the ICO Contract address, I used Jaxx (stupid me).
When I told Jaxx to send the funds over, Jaxx actually and inexplicably created a secondary address in the wallet, and then promptly deleted the private key. I've never seen this behavior from a wallet before, and it's stumped the idiots over at the Jaxx support team, because all I did was hit "send."
So, my ICO Tokens are now stuck in a secondary address that I don't have the private key for, but I'm wondering if there's any way I can unlock it using the mnemonic Jaxx used in the first place, for the original wallet. I have to assume they were derived from the same mnemonic, after all.
Before it's suggested, I've tried importing the mnemonic into MEW, but it doesn't have any way for me to sort through the millions of addresses the mnemonic creates. The address is not in the first hundred-odd pages, and the website crashes after a while, if you keep digging down through the addresses. I really need a way to sort to a specific address.
So really, my question is, is there a way I can open a specific address with a Jaxx mnemonic?
Thanks for any and all suggestions in advance.
