I understand how to obtain the Master Public Key for my Electrum Wallet.


I also know how to get the Private Keys for my individual Bitcoin Addresses in my Electrum Wallet.


What I am having trouble doing is exporting and finding out what the Public Keys are for my Individual Bitcoin Addresses within my Electrum Wallet.


Can somebody please explain the process to me of finding out how to export the Public Keys for my Addresses in Electrum.


I am talking about the Bitcoin Public Keys that are related to my Bitcoin Addresses in my Electrum Wallet.


Is it safe to give out the Master Public Key for the Electrum Wallet Addresses?

If you go to the "adresses" tab you will be able to right click and press "public key" to get your public key.

Wether or not it's 'safe' to give out your MPK depends on your definition of 'safe'. The holder of your MPK won't be able to spend your coins, it can however see all transactions that you have made and will make in the future.

No, it will not let me add the Master Public Key.......I need to find a way to export the Public Key for my Electrum Wallet Bitcoin Address.


I do not have an option to get my Public Key when I right click the Addresses Tab, it only allows me to access the Private Key with my Password.....I don't need my Private Key though.

If you want to know a publick key of a bitcoin address , then search your address on www.blockchain.info and keep the "hash 160" of your bitcoin address ( for example , 010966776006953d5567439e5e39f86a0d273bee is the hash 160 of this address 16UwLL9Risc3QfPqBUvKofHmBQ7wMtjvM);
go to http://gobittest.appspot.com/Address and put the hash 160 code in "3 - RIPEMD-160 Hash of 2" and finally click on  "1 - Public ECDSA Key".

Every single Address I try.......I input the Hash 160 into Line 3 and click Send, then it just leaves the Public ECDSA Key blank.

Maybe I just don't know how to use the program.........I just need help extracting some Public Keys from my Bitcoin Addresses in my Electrum Wallet......It should not be this difficult.

When I do that, it refreshes the entire page and has all the lines filled out with random numbers......It changes what I originally put in line 3 when I click Public ECDSA Key send button.


Not sure what I am doing wrong.

I am only trying to export my Public Key from my Bitcoin Address in my Electrum Wallet.

Anybody know how to do this......I did not think it would be this difficult to get the Public Key associated with my Bitcoin Address.

I do not see an option to find my PUBLIC KEY under the Receive Tab.

I only see the option to get my PRIVATE KEY.

I am running Electrum V 1.9.8

If you are using windows, download the new electrum version (beta 2.0b2.exe ) at : https://electrum.org/beta . After import your addresses with your seed, in the new version you can know easily the public key of a bitcoin address:

I am running Electrum V 1.9.8

You can do this with the command line:

Code:
electrum getpubkeys <your address> #default wallet
electrum -w /path/to/wallet getpubkeys <youraddress> #non-default wallet

Docs:

Code:
electrum help
electrum help getpubkeys

Don't download the beta version. That is for testing and should not be used to store significant sums.
