I'd like to exchange Ethereum Classic. Send the exact amount to the address. And currently seller ask me to confirm that I'm the owner of the wallet the transaction has been made from.
How can I do that? Does it exist sign a message option in ETC wallet like Bitcoin electrum wallet has?
I'll be grateful for your help.
yes its posible but it depends on the wallet, some wallets suports signing a message for different coins just like in coinomi wallet. you can try to use coinomi wallet for android ( available in google playstore ) just install it and then you can now sign a mesage on your desired coin.
