This is the Gaze Bounty Coin (GBC) that will eventually be converted into the Gaze Coin at the end of the Gaze Coin crowdsale.
The GBC token contract is deployed to 0x45bE456a56f6D82175Ce7f921954d2451Db73161.
GBC token transfers can be viewed at https://etherscan.io/token/0x45bE456a56f6D82175Ce7f921954d2451Db73161.
The first ever 888.888888888888888888 GBC minted - 0x3c6e0939:
Jonny has just executed the first GBC transaction:
And the transaction on EtherScan:
And Fei received the first 888.888888888888888888 GBCs:
The source code for the GBC token contract can be found at contracts/GazeBountyCoin.sol.
Your account will need to be set up as an admnistrator account in the GBC token contract.
Navigate to https://www.myetherwallet.com/ and select the Contracts tab.
See Setting Up The GBC Contract In MyEtherWallet.
Select the mint function and:
-
Enter the destination address in the _to* field. This is the 40 character public address for the account receiving the GBC tokens. This address will resemble
0xC2D7CF95645D33006175B78989035C7c9061d3F9 -
Enter the amount of GBC tokens in the _amount field. Note that this is the "natural number" for the tokens and must include the 18 decimal places, so 1.234567890123456789 GBCs is represented as 1234567890123456789 (or 1,234,567,890,123,456,789).

Click on the Access button to view the list of functions you can read or write to:
The cost of executing the mint(...) function to mint GBC tokens for a single address is about 68,000 units of gas. When
executing the mint(...) function, supply a bit more gas than the required number. 80,000 units is sufficient.
Each unit of gas is priced at the gasPrice. The transaction will cost gas x gasPrice.
In MyEtherWallet, the gasPrice is adjusted from the drop down on the top right of the web page where you can drag the slider to
alter the gasPrice used:
The lower the specified gasPrice, the longer the transaction will take to get mined. Following is the current transaction cost:
- Low
gasPrice1 Gwei (1,000,000,000 wei) - actual transaction cost will be around 0.000080000 ETH (~ USD 0.03) - Medium
gasPrice4 Gwei (4,000,000,000 wei) - actual transaction cost will be around 0.000320000 ETH (~ USD 0.12) - High
gasPrice20 Gwei (20,000,000,000 wei) - actual transaction cost will be around 0.001600000 ETH (~ USD 0.60)
