    Some ETH related question if one can answer:

    1) What is a dev wallet ?
    2) What is ETH mixer ?
    3) How to ask a buyer to confirm ownership of a ETH wallet ?

    1. Are you sure you dont mean a contract address? Not sure what difference a "dev" account would be otherwise.

    2. Same as a btc mixer/tumbler. Uses multiple inputs and outputs to try to hide the origin.

    3. If its a buyer cant you just ask them to send a small transaction to prove it? Other than that like all cryptos its public private shared key based. So they can sign (ie encrypt) a message using their private key. You can then use their public key (ie wallet address) to decrypt the message. If it works it proves they have control of that wallet. Problem with this is that unless they are technically able to do this process on an offline secure pc then they run the risk of compromising their private key. Which is always a bad idea.

    myetherwallet does everything in javascript afaik so is client side and probably an option if your someone already comfortable with using your private key on there. Wouldnt recommend it though.

    Much better. myetherwallet is open source so can be set up on a clean offline pc

    As for proving that person actually has the right to use that private key and is not a robbing bastard then I dont think you can.

    First of all thanks for such a detailed answer, something that compels me to go and check your previous posts. By dev account , I mean a developer account. I checked about that wallet and someone mentioned that it got huge amount of Ether from a dev wallet. Also, the wallet has a number of airdrop coins, why will an exchange with millions worth ETH do airdrops ?

    Oh I see, an address owned by a developer - thought you meant a specific type of address :)

    As for airdrop coins. It could depend on the airdrop - If the airdrop rules stated that they go to any Ethereum address with above 'x' balance (eg trx recently) then yeah exchange addresses would get them. Its then up to the exchange whether or not to distribute them to the real owners of the ETH. If an exchange doesnt support an airdrop then it should only be fair that they keep the tokens publicly visible in the ETH wallet.

    It could of course just be some individual with loads of ETH. Im curious now though...could you PM me the address?
