var code = "formatted";
Hello, guys. Can some one help me please :) . I am playing around with crowdsale from ethereum official page. In remix I am creating contract, I put information like this: "0x14723a09acff6d2a60dcdf7aa4aff308fddc160c", 100,5,50,""0x0fdf4894a3b7c5a101686829063be52ad45bcfb7"
So, my ICO deadline is 5minutes, but it's not counting
when I click on deadline every time it shows:
0: uint256: 1521446508
When I check token award address or where to send token after successful ico, shows perfectly
Thanks ;)
Hi, is it possible to get from RCP API the same information as I get there https://www.etherchain.org/account/974b468793fa63cf46b04fbd8d9bc0cfb6d5f6fe
In other words I need to get transactions for some address.
I see that transaction 0x8a16153a.. is included in block 5014010. But when I get data from web3.getBlock(5014010) and analyse it, there are no transactions, that has "to" address that equals 0x974b4687...
How can I find this transaction related to address 0x974b4687 ?

Hi! I'm new to blockchain development so I apologize if this is a stupid question. I've been doing some development on a private blockchain and was able to successfully deploy some contracts and call the contract functions on my end with no issue. However, I'm running into an issue where my peers can't seem to access those contracts on their end. I gave them the ABI and the contract address, but when they try to call the function, they get an error. I get the feeling that we aren't connected to the same private blockchain? In order to connect to the blockchain, I sent them the genesis file and they did the geth init setup then connected via geth attach. Are we doing something wrong here?
hi friend how i can set price in fraction with 18 decimal places
require(balanceOf[_to] + _value > balanceOf[_to]) equals require(_value > 0)?
i first come here
I am new to blockchain. I want to know how to run the various codes given in the examples. How do run the code or get to the interface?
Please help on how to send token to multiple addresses..

Hello, I bipul Khan, I am very new on Block chain technology. but I am ready to start the ethereum smart contract . I am very interested to do. please guide me how to start..

Good afternoon everyone (Brazil), a help for the beginner here .... How do you put balance in a Wallet in the ETH test network ?!

I'm calling the API to create wallet (on the test network) ok, now I need to program to send balance but with zero balance it will not work is not. So how can I put a balance in a wallet on the test network ?!

All adjustments are welcome!

@Magnoes your local blockchain is not accessible by anyone else from other system.In order to access your contracts your peers need to download you full blockchain.

I'm messing around with making my own smart contract with the Ethereum Wallet but when I paste the code from ethereum.org/token I get an error on the second line that causes it not to compile. Any ideas?

Hey I am working on a POC for keeping land record on Blockchain. Can anyone help me with the reference code Please .
@Jvckson the same problem with your , is the example contract available ?
Error tips: Functions in interfaces should be declared external.
One big problem: Tomorrow issued new official Ethereum wallet 0 10 has totally incompatible "Deploy New Contract" section with official samples of token on Ethereum.org website. Is here one, who know solution ?
so the official samples is work in wallet 0 .9 ?
@Evanlai8 yes, and every day 6GB of your SSD is eaten and it is not possible to back-up admin account for Token account - very dangerous detail
The new update 0.10.00 not working on my mac... any suggestions?
It says connection error
I want to create a signed transaction using C#, which will later be used by Nethereum via JSON-RPC to call eth_sendRawTransaction. Without using var web3 = new Web3 ();
Ima make a shitcoin
Shitcoins are kool
Seems easy

Hi! I am new to crypto-world and I have some questions. Idk is it a right room to ask. The question is about ICO. I have read a couple of articles to build a model in my head of how it works. So, if i understood correctly, I need 2 contracts for the ICO:

1) My new coin contract (with transfer method).

2) Crowdsale contract which accepts ETH and give users my tokens in reward.

I can not understand few things:

1) What would prevent users from starting exchanging my coins just after they get it? They have access to transfer method. They say "exchanging coins is allowed after ICO is ended" in articles, but i can't find any code in examples that disallows it.

2) Is there a connection between my coin contract and user's wallet? Can user see that he has some number of MyCoin on his wallet balance? Or the only place where his balance is stored is storage of my contract?

The code for advance coin will not compile

What's the mechanics?
