relexdistributor's Issues

What if the source account has too little ethereum?

This is current version line 92
var gas = await function.EstimateGasAsync(from, null, null, to, amountInEthereumFormat);

In a robust implementation, we probably want to be able to do a test run that doesn't actually do transactions but just adds up the Ethereum amounts needed so that we can make sure that the account has enough to fund the gas needed. We also probably want to be able to adjust gas amounts off of the machine recommendation as a program parameter.

Output parsing

This is line 83:
Console.Write("Sending {0} Relex tokens to {1}... ", amount, to);

But the CSV has the first column being addresses and the second column being amounts so shouldn't it be
Console.Write("Sending {1} Relex tokens to {0}... ", amount, to);

Insufficient comment

Here are lines 84 and 85 of the current version
//the real transactional amount needs to be multiplied by the decimals of Relex Token
amount *= (long)Math.Pow(10, RelexDecimals);

For someone who is not that familiar (it's been a long time since I had anything to do with C of any variant), you probably want a little more detail explaining what you are doing here. Why must the stated transactional amount need to be modified?

Allow for different address and port for Geth

Instead of hard coding an address, give a prompt for the address and port and if you just hit enter, you use the default of 127.0.0.1:8545
