Please Note

With Spacecoin-QT the commands will need to be entered in the console. This is accessible at Help -> Debug Window -> Console.

Pubkeys are necessary when using CryptoConditons modules such as Tokens.

A wallet with a set pubkey will send change from transactions to the address of that pubkey.

Find A Pubkey

1. Navigate to spacecoin-cli or Console depending on your wallet.

2. Enter the command validateaddress yourSpacecoinAddress.

   Example: validateaddress RC7X8pGZ5GJH5hCHFb6skbsrfg5oEHjc2y

   It will return:

   {
     "isvalid": true,
     "address": "RC7X8pGZ5GJH5hCHFb6skbsrfg5oEHjc2y",
     "scriptPubKey": "76a9141f142028ff5ef909dd52cba1d920a212c3132ce588ac",
     "segid": 63,
     "ismine": true,
     "iswatchonly": false,
     "isscript": false,
     "pubkey": "039e1f9a06d9d41981d0cc1c380d0965e82250d436523e18b42832b1e41f037e00",
     "iscompressed": true,
     "account": "Example Address"
   }
   

   In the returned output, 039e1f9a06d9d41981d0cc1c380d0965e82250d436523e18b42832b1e41f037e00 is your pubkey!

   The pubkey field will only be returned if "ismine": true. Your wallet must own the address.

Make A New Pubkey

1. Navigate to spacecoin-cli or Console depending on your wallet.

2. Enter the command getnewaddress.

   It will return a new address. Example: RC7X8pGZ5GJH5hCHFb6skbsrfg5oEHjc2y

3. Enter the command validateaddress yourNewSpacecoinAddress.

   Example: validateaddress RC7X8pGZ5GJH5hCHFb6skbsrfg5oEHjc2y

   It will return:

   {
     "isvalid": true,
     "address": "RC7X8pGZ5GJH5hCHFb6skbsrfg5oEHjc2y",
     "scriptPubKey": "76a9141f142028ff5ef909dd52cba1d920a212c3132ce588ac",
     "segid": 63,
     "ismine": true,
     "iswatchonly": false,
     "isscript": false,
     "pubkey": "039e1f9a06d9d41981d0cc1c380d0965e82250d436523e18b42832b1e41f037e00",
     "iscompressed": true,
     "account": "Example Address"
   }
   

   In the returned output, 039e1f9a06d9d41981d0cc1c380d0965e82250d436523e18b42832b1e41f037e00 is your pubkey!

Using A Pubkey

There are 2 ways to tell a wallet to use a pubkey.

Setpubkey Command or Start Wallet with Pubkey

Setpubkey Command

Start Wallet With Pubkey

1. Start the wallet with the -pubkey=YourPubkey command line option.

   Example for Spacecoind: ./spacecoind -pubkey=039e1f9a06d9d41981d0cc1c380d0965e82250d436523e18b42832b1e41f037e00

   Example for Spacecoin-QT (windows): Create a shortcut of spacecoin-qt.exe. Right click on the shortcut and select Properties. Then add your pubkey to the end of the target field. spacecoin-qt.exe -pubkey=039e1f9a06d9d41981d0cc1c380d0965e82250d436523e18b42832b1e41f037e00
