@parzinskij You are not the first and will not be the last to come up with that "solution" to the "problem" of payment for gas usage. Although it may be appealing to let your user pay with your own token, this will always be a workaround. Since all the transactions of the contract will be computed on the EVM you'll have to pay in ether for every transaction. So you can make your users pay you in funnymoney but the real transaction costs will still have to be payed, by you, in ether. There are a lot of people out there, trying to use selfmade tokens to pay for transaction cost, but they all have the same problem: Their user might be able to pay with tokens, but the real transactions on the Ethereum Blockchain will always be payed in Ether. Simply no way around it. So you'll have to set up an token und distribute it to all your user (read, sell it to them) and then they can pay you to pay the real costs. It's simply not possible to use DApps "for free", someone has to pay the bill.

@pirokars despite all the warnings in the ethereum wallet app or on the various website, you still don't know, that you shouldn't use real ether on the testnet chain?
in fact, testnet ether can not be used on the real chain an viceversa
so to get your money: just make yourself a wallet with or the like

can someone help me with send token

const defaultEstimateGas = 50000000
const myContractSend = web3.eth.contract(abi).at('0x446c3Ae44f43BCc9a51F2582Af76FD050b8916A8')
myContractSend.transfer.sendTransaction('0x0C22B633bc8372a1956716330E34Eb548f3Df2ac', 2, {
    gas: web3.toHex(defaultEstimateGas)
}, function(a, b) { console.log(a, b) })

it gives me an error Error: invalid address
but those addresses listed are valid

I think sendTransaction is missing from: something after gas: .... @mjbquieta
I think the error message can be better.

Need help starting a smart contract for company shares as well as a token
