How Can We Help?
This section describes all Ethereum ICO WordPress Plugin configuration settings.
Token Symbol
The symbol of your ICO token defined in your ERC20 Token contract. E.g. TSX, not “Test Coin”. In the ERC20 standard it is defined as
function symbol() view returns (string symbol)
It also can be defined as a simple property:
string public constant symbol = "TSX";
Gas Limit
It is the maximum amount of Gas to be used by your investors in a token purchase transactions. The default 200000 is a reasonable value for most of ERC20 tokens.
Increase this value if your ERC20 Token contract requires more Gas.
This value would be set in the MetaMask dialog field.
Gas Price, Gwei
It is the amount of Ether to pay for a 1 Gas unit in Gwei.
Gwei is a 1000000000 wei, or 1/1000000000 Ether
The default value of 21 Gwei is reasonable in most cases.
This value would be set in the MetaMask dialog field.
Base currency
The base currency code to show in the token sell widget, progress bar, e.t.c. In most cases the default ETH is OK. Use USD or other fiat currency three letter code if you have implemented oraclize.it interface in your Crowdsale smart contract. Make sure to configure openexchangerates.org App Id if non-USD fiat currency is used here.
Your Crowdsale contract should be able to work with it. You can use the Crowdsale Contract and ERC20 Token Development Service to let us do this job for you.
Base symbol
The base currency symbol to show in the progress bar and purchases table widgets. In most cases the default Ξ is OK, which is the Ethereum symbol.
