How to sign a BTC wallet

 

Sign and Verify Messages

Sometimes it's helpful to prove to another party that you control an address, but without transferring funds. If you are wary of submitting photographic verification information, you can instead opt to sign a transaction from an address you have funded in some cases withdrawal addresses also can be used in your CEX.IO account history.

Multibit:

Message signing is done through the Tools > Sign Message main menu option. Enter the address to sign from in the “Address” field:

Then enter your CEX.IO BTC deposit address, unless otherwise requested, in the “Message” field:

Pressing the "Sign Message" button will create a signature which, together with the message, can be given to our representative as proof that you have control of a bitcoin address associated to your CEX.IO account.

Electrum:

Message signing is done through the Tools > Sign/verify message main menu option.

Enter the address to sign from in the “Address” field:


Then enter your CEX.IO BTC deposit address, unless otherwise requested, in the “Message” field:

Pressing the "Sign Message" button will create a signature which, together with the message, can be given to our representative as proof that you have control of a bitcoin address associated to your CEX.IO account.

 

Armory:

Message signing is done through the Tools > Message Signing/Verification main menu option.

Enter the address in the “Sign With Address” field:


Then enter your CEX.IO BTC deposit address, unless otherwise requested, in the “Message” field:

Pressing the "Bare Signature (Bitcoin QT Compatible)" button will create a signature which, together with the message, can be given as proof of control of an address.

    Is it possible to sign a coinbase wallet? I don't really feel like getting armory and downloading the whole damn blockchain with the exclusive purpose of account recovery.

    averagejoey2000 You may sign your coinbase wallet if you have the access to its private key. Please check with coinbase if the wallet used to deposit funds to CEX.IO is the same as the one which is used to get funds deposited on your coinbase account.
