Just and FYI, I opened an issue to see if the solidity team can prevent this sort of scam in the future. ethereum/solidity#4315

-------------------version-------------------
Solidity version
Current version:0.4.24+commit.e67f0147.Emscripten.clang
---------------------warnning-------------------
browser/BNBFormat.sol:31:3: Warning: This declaration shadows a builtin symbol.
function assert( bool assertion)
^ (Relevant source part starts here and spans across multiple lines).

-------------------------code-----------------------
function assert( bool assertion) internal pure returns (uint256){

WHY has this warnning? how can i clear that?

@phiferd

assert is a reserved word. https://solidity.readthedocs.io/en/develop/control-structures.html#error-handling-assert-require-revert-and-exceptions

We are developing a DAPP based on ethereum. Current we are developing based on testrpc and its working perfectly.
We do want to decide on where to deploy DAPP.
Can we deploy on public Ethereum blockchain.

Is there any other variables that need to be considered when deployed a smart contract of the decentralised application other than token in ethereum network ?

What about decentralised private ethereum blockchain.

@phiferd

Deploy to the test net first. @bensonkb

how to find constructor arguments at the end of byte code

bitcoinpure01

@bitcoinpure01

@bitcoinpure01
Error! Unable to verify source code
Missing Constructor Arguments for function EtherToken(address admin, address feeAccount, address accountLevelsAddr, uint feeMake, uint feeTake, uint feeRebate)
00000000000000000000000033daedabab9085bd1a94460a652e7ffff592dfe3000000000000000000000000fec8bb460c2501b8c1d4801f34b4408c1fbbccb1

Which when decoded would be

Arg [0] : 00000000000000000000000033daedabab9085bd1a94460a652e7ffff592dfe3

Another quick and dirty way of figuring out what your constructor arguments are is to compare both the browser solidity / remix compiled byte code and compare this with the input creation byte code. If you look carefully you will notice that the additional hex codes attached at the END of the input created byte code. This is your 'Constructor Arguments'

Do not share your private keys, seed phrases, or passwords with anyone pretending to want to help, unless you want to lose your Ether and tokens.

bitcoinpure01

@bitcoinpure01

@phalexo help?

phiferd

@phiferd

@bensonkb ok. I recommend you do additional testing on the test network. You can find some faucets that will send you free test network eth. On the test net, you'll get a much better idea about how your app will perform (e.g TX time). Depending on what you're trying to do, you might want to run some sort of alpha version with a subset of users before flying to the main net.

Benson

@bensonkb

@phiferd : Sure. That will be Fine.
