hello everyone
i create a token but i need send 0.50000000 CoinExample
but token send only 1 or 2 or 10
integer only
how to send decimals values only?
There is an example of how to send funds on this page
The interface has ability to take decimals
I have 4 questions on token issuance with Ethereum:
  1. How much ether should I except to pay if I create a token inside Ethereum?
  2. Will a higher transaction volume with this token mean a higher cost?
  3. Do transactions in Ethereum carry a transaction cost in ether/gas? Who covers the cost and how do you avoid spam transactions?
  4. Is there a transaction confirmation time with tokens inside Ethereum?

Hey guys, built a web app that allows you to run any deployed contract by pasting the abi and contract address in the url params or in the text boxes on site. This is great for if you have smart contracts but no ui to interact with it. Here is the link:

to run an dApp with the url simply go:

let me know what you guys think!
example contract in url:,%22inputs%22:%5B%7B%22name%22:%22vendor%22,%22type%22:%22address%22%7D%5D,%22name%22:%22trade%22,%22outputs%22:%5B%5D,%22payable%22:false,%22type%22:%22function%22%7D,%7B%22constant%22:false,%22inputs%22:%5B%7B%22name%22:%22username%22,%22type%22:%22string%22%7D,%7B%22name%22:%22location%22,%22type%22:%22string%22%7D%5D,%22name%22:%22addUser%22,%22outputs%22:%5B%7B%22name%22:%22%22,%22type%22:%22string%22%7D%5D,%22payable%22:false,%22type%22:%22function%22%7D,%7B%22constant%22:false,%22inputs%22:%5B%7B%22name%22:%22vendor%22,%22type%22:%22address%22%7D,%7B%22name%22:%22isPositive%22,%22type%22:%22bool%22%7D,%7B%22name%22:%22message%22,%22type%22:%22string%22%7D%5D,%22name%22:%22giveReputation%22,%22outputs%22:%5B%5D,%22payable%22:false,%22type%22:%22function%22%7D,%7B%22constant%22:false,%22inputs%22:%5B%7B%22name%22:%22user%22,%22type%22:%22address%22%7D%5D,%22name%22:%22viewReputation%22,%22outputs%22:%5B%7B%22name%22:%22%22,%22type%22:%22uint256%22%7D,%7B%22name%22:%22%22,%22type%22:%22uint256%22%7D,%7B%22name%22:%22%22,%22type%22:%22uint256%22%7D,%7B%22name%22:%22%22,%22type%22:%22uint256%22%7D,%7B%22name%22:%22%22,%22type%22:%22uint256%22%7D%5D,%22payable%22:false,%22type%22:%22function%22%7D,%7B%22payable%22:false,%22type%22:%22fallback%22%7D,%7B%22anonymous%22:false,%22inputs%22:%5B%7B%22indexed%22:true,%22name%22:%22user%22,%22type%22:%22address%22%7D,%7B%22indexed%22:true,%22name%22:%22message%22,%22type%22:%22string%22%7D%5D,%22name%22:%22_positiveReputation%22,%22type%22:%22event%22%7D,%7B%22anonymous%22:false,%22inputs%22:%5B%7B%22indexed%22:true,%22name%22:%22user%22,%22type%22:%22address%22%7D,%7B%22indexed%22:true,%22name%22:%22message%22,%22type%22:%22string%22%7D%5D,%22name%22:%22_negativeReputation%22,%22type%22:%22event%22%7D,%7B%22anonymous%22:false,%22inputs%22:%5B%7B%22indexed%22:true,%22name%22:%22username%22,%22type%22:%22string%22%7D,%7B%22indexed%22:true,%22name%22:%22location%22,%22type%22:%22string%22%7D,%7B%22indexed%22:true,%22name%22:%22user%22,%22type%22:%22address%22%7D%5D,%22name%22:%22_addUser%22,%22type%22:%22event%22%7D,%7B%22anonymous%22:false,%22inputs%22:%5B%7B%22indexed%22:true,%22name%22:%22vendor%22,%22type%22:%22address%22%7D,%7B%22indexed%22:true,%22name%22:%22buyer%22,%22type%22:%22address%22%7D%5D,%22name%22:%22_newTrade%22,%22type%22:%22event%22%7D,%7B%22anonymous%22:false,%22inputs%22:%5B%7B%22indexed%22:true,%22name%22:%22user%22,%22type%22:%22address%22%7D,%7B%22indexed%22:true,%22name%22:%22positive%22,%22type%22:%22uint256%22%7D,%7B%22indexed%22:true,%22name%22:%22negative%22,%22type%22:%22uint256%22%7D,%7B%22indexed%22:false,%22name%22:%22total%22,%22type%22:%22uint256%22%7D,%7B%22indexed%22:false,%22name%22:%22burnedEth%22,%22type%22:%22uint256%22%7D,%7B%22indexed%22:false,%22name%22:%22burnedCoins%22,%22type%22:%22uint256%22%7D%5D,%22name%22:%22_viewedReputation%22,%22type%22:%22event%22%7D%5D/0x706af303364dc89a6b8dba265947442b05e84776

Like I said, try to check your account on and see if the ether is in it.
It is very simple, copy and paste your account number into the search box on the top of the page on and click go. You should see the results.

Hi, I'm working on the Crowdsale tutorial. I can't figure out how to get the association to call the safeWithdrawl() function. It seems that it needs to be executed by the address where the Association contract was deployed. It appears that Mist does not allow me to select that address as an origin. Am I missing something?
Matthew Orris
It seems to me the way this tutorial is setup that the Association is correctly the beneficiary of the tokens, but that the Association contract has no function that is able to withdraw the ETHER funds that were sent to the CrowdSale contract. Is it possible to use geth to call the safeWithdraw() function?
hi, looking for an open source exchange that i can setup in my country since none exists for ethereum. i am looking for someone who can offer their development skills to customise an open source platform. i am wiling to pay but please understand this is a new startup venture and i will be putting in my own funds and sweat equity. so go easy on me with the rate :)
has anybody successfully created their own cryptocurrency

On the testnet, sure ..
hi all i am net to this and trying to deploy a token but i believe my codes are wrong, can some one help me with it.

pragma solidity 0.4.8;

contract MyToken { event Transfer(address indexed from, address indexed to, uint256 value);
/ This creates an array with all balances /
mapping (address => uint256) public balanceOf;
/ Initializes contract with initial supply tokens to the creator of the contract /
function MyToken(uint256 initialSupply, string tokenName, uint8 decimalUnits, string tokenSymbol) {
balanceOf[msg.sender] = initialSupply; // Give the creator all initial tokens
name = tokenName; // Set the name for display purposes
symbol = tokenSymbol; // Set the symbol for display purposes
decimals = decimalUnits; // Amount of decimals for display purposes
/ Send coins /
function transfer(address _to, uint256 _value) {
/ Check if sender has balance and for overflows /
if (balanceOf[msg.sender] < _value || balanceOf[_to] + _value < balanceOf[_to])

/* Add and subtract new balances */
balanceOf[msg.sender] -= _value;
balanceOf[_to] += _value;

I'm trying to figure out the cost of deploying and maintaining a coin, anyone know where I can find such resources ?
