Minting ZeroCoin

Minting a ZeroCoin means destroying a fixed number of GravityCoin and turning them into “ZeroCoins” which are tokens to redeem completely new “clean” GravityCoins.

Start the GravityCoin wallet. Click on the ZeroCoin tab on the top section. In the dropdown menu at the bottom, choose a denomination (1, 10, 100, 250, 500) in which to mint the ZeroCoin. A mint fee of 0.001 GXX will be charged regardless of how many coins you mint.

After an amount is chosen, click on the Mint ZeroCoin button. It takes about 6 confirmations before you can spend the ZeroCoin you have just created. The newly minted ZeroCoin will appear as “New” in the list.

Note: It is always recommended to backup your wallet.dat whenever you do a mint. You can do this by going to File > Backup Wallet.

Spending ZeroCoin

The longer the time between the initial mint and the subsequent spend, the more potential privacy you have. We recommend minting some coins beforehand and spending them when you require them rather than immediately spending your mints as soon as they are confirmed.

If the mint has 6 confirmations or more, select the denomination of the coin you minted (1, 10, 100, 250, 500) that you want to spend. (To use Third-party spend: Uncheck the ‘Spend To Me“ checkbox and choose an output address.) After that click on the Spend ZeroCoin button. This will take awhile, and your ZeroCoin will appear as “used” after it is completed.

Your ZeroCoin is now redeemed into GravityCoin and will be sent to a chosen (Third-party) GravityCoin address or a random chosen GravityCoin address with no previous transaction history.
