@sadikt you can try creating a contract on a ethereum test network where it won't cost real ether
i tried creating a contract and its hung in "Creating Contract" with 0/12 confirmation

Hi. Sorry if my question is elementary. What is the language in which ethereum code is written?

visit this site for test eth https://faucet.metamask.io/
I requested said no account
i have already create contract
using code provided here "THE CODE" but problem is that when i am verifying it on etherscan then return error
Error! Unable to generate Contract ByteCode and ABI
are you on metamask ?
no i am not
I was trying to get the miner to start in geth and it returns null

yes I am on rinkeby test net

Please on which situation can I use react-auth truffle framework ?

Did you try turning it off/on?
s everything have to be so freaking frustrating? I simply want to put an Ethereum Wallet on my Raspberry Pi desktop so as to deploy an ERC20 Token I wrote. Is there a simple download-Install procedure? Thanks
Alex Lacey
Dumb question: when creating a token that runs on the Ethereum blockchain, is it possible to Airdrop the coin to every single ether wallet on earth? Or is there some restriction on that?
Alex Van de Sande
yes it’s possible. It might be expensive on gas, or take some creativity on the development side
Alex Lacey
So I would need to pay for the gas to distribute it? (I assume this is obvious but I just want to make sure because I'm super new at this)
Alex Van de Sande
You would need to pay the gas to deploy it, and would need to do something on the deployment side to set up all balances
Alex Lacey

Isn't setting up the balances just boilerplate code? Or would it be complex?

Also, would the gas required to airdrop to everyone be prohibitively expensive?

@bensonkb Thanks!
stupid question, once you deployed a contract, can you make changes to the code?
hey guys, i have a simple question: in the erc20 example we have tokenRecipient sender = tokenRecipient(_sender) where tokenRecipient is declared as an 'interface' outside of the contract class
function approveAndCall(address _spender, uint256 _value, bytes _extraData)
returns (bool success) {
tokenRecipient spender = tokenRecipient(_spender);
if (approve(_spender, _value)) {
spender.receiveApproval(msg.sender, _value, this, _extraData);
return true;
interface tokenRecipient { function receiveApproval(address _from, uint256 _value, address _token, bytes _extraData) public; }
the interface is called upon just by calling it? Also, how can you only send _sender variable in the tokenRecipient call if it takes 3 values?
or rather, the only function inside of it takes 3 values, so what are we passing _sender variable to?
Hi I am trying to create a token and I have no Idea where to start. I am on the create my own cyrpto page however the site is not allowing me to input information
@CCASHDAN Doesn't the page tell you to paste the code into Mist? I think you need to install Mist to follow that tutorial
