can any one suggest me how to build smart contract more cost efficiently ?
i have a question if 100 transactions were called for my contract from 100 different people , is there any way to build cost efficiently, like sending multiple transactions in one transaction.

is there any source to get testnet (ropsten) ether sent to my testnet address? or do i have to ask ppl to give each time?
my mist wallet seems to be stuck on 99%
@Ectsang There is a testnet ether faucet for both Ropsten and Rinkeby. Google for it.

Hello. where can I download the official miner myself?
Help with truffle. Trying to migrate sample truffle project on rospnet and get following message "Error: The contract code couldn't be stored, please check your gas amount." event though the contract is correctly created. https://ropsten.etherscan.io/tx/0x9444ba6bf208bd3c1d482f0fd0a28ae322b5b39f479d0a7475be6fd343285853

hi There. could anyone tell me where to start create coins?
you use your ethereum wallet
with some ether
but that is not as easy as said
you have also to promote that coin
i have now created this coin website
its not perfect but i hope to get some feedback here i will use ethereum at the begining but will be longterm transactioncost aware.
i cant create a token nor doesnt the ether wallet show me my 1.95 ether balance since its not updated and it doesnt update at all what can i do
Im pretty frustrated anyone care to give me some wisdom?
hello. In the "create a coin" tutorial says to open a wallet app. I cant find it. Anyone could gimme a hand?
How do I know when a transaction is completed? All I see is a shiny multi colored ball next to the words saying creating contract
you can always check etherscan.io
well it says success so it must be all good
So who wants some SkipCoin? First Cryptocurrency used to buy time. Not in a literal sense, but used to bypass Ads and reduce buffer time while trying to view internet content.
it's a great shitcoin

hi! everyone, I am a beginner and am struggling to find a tutorial where a contract is using an external api to give an outcome. I am sure its called oracle but i am not able to code it. Can someone give an example by using a Weather API to come to an outcome in something like a bet contract.
what are the current transaction costs in the ethereum system?
Much cheaper than for bitcoin, so you can get off your shtick crying about transaction costs.
@siddharthswarnkar I think this one looks up flight records from an API so may help: https://etherscan.io/address/0xec2374b274a8c04c0ec52dab10bc78078589ab62#code

fundingGoal = fundingGoalInEthers 1 ether;
deadline = now + durationInMinutes
1 minutes;
price = etherCostOfEachToken * 1 ether;

how to change to: 0.001 ether = 100 token? pls help

price = 100000

Hey guys, anyone know of similar tutorials like the Truffle Pet Store DApp. I'm looking for more through examples.

hi there, i was wondering if anyone would be able to tell me how to export the excess tokens back to the token owner after a crowdsale has finished?

i used the https://www.ethereum.org/token#full-coin-code and https://www.ethereum.org/crowdsale#the-code code and the beneficiary was a multisig contract i created, however when transferring the inital amount of tokens to the crowdsale after creating it mist says the tokens was sent to the token contract, i am then able to buy tokens as long as i have transferred enough to the crowdsale, however how do i transfer tokens back after the sale has ended?

hi all
i have to make an project for university and it's like downloading already uploaded files(in contracts) dapp
but i have no idea how to start
any sugestions?

Hi all, any info or links on how to use the new zksnarks feature of byzantium? I can't seem to find any info on that.
@Orionsz I'm new to the solidity coding part, as I check in open zeppelin they have lots of folder to create a token. However, ethereum page give only one page code to deploy the token. So, concern is which one is better to code??
