Now you log in on the Dropd site(https://dropd.tokenlab.io), deposit your payment to a Dropd contract address to the ico tokens But i accidentally made a ethereum deposit to the Expanse wallet instead of the contract address. Now my eth isnt showing, so i think its gone. But im not at home right now, so i cant check it.
I hope this is clear.
i think its a wallet because op already said that it was a wallet . i agree that contacting thier support is the best way to recover his coins if they will still give it back but i think they will as long as they are legit and not scam .
the transaction should show up after he click on the link on the wallet that he is using ( this can be done right after he send the coins ) or he can manually do it by pasting his own eth address or its reciever address on etherscan or etherplorer .
Sending ethereum to a token address of their own is something not possible to recover IMO but atleast he can try them and see is there a chance.
