I have an issue following the instructions for remix for deploying your first contract. https://medium.com/@jamesray_56543/unfortunately-i-dont-see-any-of-this-d87ca724a22a.

@blacksausage it seems that Mist isn't really ready for use yet, best to wait until it is usable with later releases that aren't pre-releases.

@phalexo

@blacksausage It does not look by your post that you have actually put any ether into that Wallet. If you used Ethereumwallet to create that wallet contract and you've synchronized with the blockchain, perhaps it is a collision, i.e. you have stumbled into someone else's wallet. I don't know what the odds are for two different sets of keys to generate the same address, but it sounds interesting if it did happen.

can somebody guide me

hello

can someone explain me the stepps to create a coin/wallets system and the possibilities i can alter the shape of the coin?

Hey. Is it possible to send to multiple addresses with an existing Ethereum Token?

I used about 10$ worth of Ether

while setting up the wallet

now I cannot find it

any idea where to look

hey guys

what is a pragma solidity and can i change it?

and i got this error actually Undeclared identifier.
require (_to != 0x0); // Prevent transfer to 0x0 address. Use burn() instead

I'm having issues with https://www.ethereum.org/crowdsale on the new version of mist is there a way to update mist solidity compiler?

Hi guys, quick question:

function foo() payable {
someAddress.call.gas(250000).value(msg.value)();
}
In that case, who is paying for the 250000 gas? Is it the msg.sender or the contract?

Hi guys! I've been having an issue with the Shareholders Association on the latest Ethereum Wallet version (0.9). Here's the error:

Variable is declared as a storage pointer. Use an explicit "storage" keyword to silence this warning.

Was putting storage after the datatype and made it to:

string storage description;

But it still isn't working. Any thoughts on this??

@jjpsuarez1113 same issue the compiler doesn't work

univers3

@univers3

Hi guys,
I was creating my first token on the ethereum network.
I saw that a lot of people used SafeMath in their contracts.
Using the updated example on the Ethereum's token creation page is still necessary to use it? Are there things to take care with that code?

jjpsuarez1113

@jjpsuarez1113

@kingassune glad that I wasn't the only one experiencing this. It seems like the compiler of the Ethereum Wallet isn't updated. It's still running on 4.13. Can we somehow update the compiler version of the Ethereum Wallet?

hi guys

i just want to ask for the state of dapps

so in order to make it running do i need to make it from meteor js ?

@MidnightLightning Hello! How do I use Remix to compile Solidity code and use it in Ethereum Wallet? It seems that the compiler needs to be updated in order to compile the Shareholders Association code in the tutorials. And, I read a few threads back that I can use Remix to compile the contract instead. How will I do it? Thank you.

weijin

@weijinxy

@jjpsuarez1113 you should create private ethereum net, and choose web 3 Provider environment

jjpsuarez1113

@jjpsuarez1113

I'm on Rinkeby and Remix isn't detecting my account even if I connect it to the localhost. I'm using Ethereum Wallet 0.9.0.

@MidnightLightning

In the right sidebar of the Remix interface, switch to "Settings" and set the compiler to whatever you want. Click the "Compile" button to make sure your contract is re-compiled with the new version. Switch to the "Contract" tab, and under the blue header for your contract, click the "Contract details (bytecode, interface, etc.)" link. That will expand out a bunch of raw data about the contract, including a "Web3 deploy" script, and the full Bytecode, which you could copy and paste into the Ethereum Wallet software as "transaction data" to send.

what is a pragma solidity and can i change it?

@Saoming The first line of a Solidity script often includes a "pragma" line that indicates which version of Solidity is needed to compile that code. If you have "undeclared identifier" errors, that likely means the compiler you're using is too old and doesn't know those new commands.

Brooks Boyd

@MidnightLightning

so in order to make [DApps] do i need to make it from meteor js ?

Meteor is not needed to make a DApp, thought it does make it a lot easier. You can just use the web3js infrastructure to add basic communication to the Ethereum network to your web application.

someAddress.call.gas(250000).value(msg.value)();In that case, who is paying for the 250000 gas? Is it the msg.sender or the contract?

@squlio-jmul The msg.sender is. That command limits the sub-transaction to 250,000 gas, which the sub-transaction might not use all up, so it might not need to all be paid for.

can someone link to the best way to purchase ethereum in USD... or the process of downloading a wallet etc...

@ReneRomoJr For someone just getting started, Coinbase is an easy way to get some ether for USD.

great idea for ether. http://etherhouston.org
