INVESTOR AND BOUNTY HUNTER: How to avoid scams?

[Dabll_kilDaRk0]

It is useful to know from the very start which team has a sufficient level of knowledge in coding ...

[Banny_hopyy94]

There are many signs of scams during the ICO, but I would like to draw your attention to one, in my opinion the most important.
This sign: AUDIT smart contract. The quality of his code.
Before deciding to participate in a particular project, you need to know: Was an audit conducted?
If NO, then it would be good to audit yourself.
Previously, it was expensive, but now you can order an audit for free.
It takes you several minutes to complete the form and as a result you will receive important information that will help you save your money and time!

Who will invest in the project or advertise it if its tokens can be stolen by any hacker?

I added a smart contract for the audit, but I can not believe that there will be a result.

https://github.com/EIPlatform/EMI-Token/blob/master/EMI.sol

Suspicious project.

[BinPooool]

We need to check all the smart contracts)))

[Linaut7ez2]

I need to know if there are errors in the code.

Cool! If earlier it was possible to check all the smart contracts, how much money investors would be saved!)

[DnovorezoV_aA]

It seems that Callisto will indeed audit all suspicious smart contracts.

[mileniumv23]

Well done! Great idea! For a long time it was necessary to bring scammers to the surface.

[Linaut7ez2]

Suspicion of a scam and unprofessionalism.
To make a decision, I need to know if there are any critical errors in the code.
How long will the audit be conducted?

When will the results of the audit be? Where are the links to the reports?

[GraBitCoin]

When will the results of the audit be? Where are the links to the reports?

I do not know the exact answer. The results will be reported to us by those who send information for the audit. The answer will come to the email they specified when completing the form.

[CoinDrop99]

Yes, knowing the information helps to make the right decision. Already ordered a lot of audits ... let's see what happens.

[KarambaCoin]

Now most projects do not have any smart contracts at the start. They first collect money)))

[nikusPiks]

Now most projects do not have any smart contracts at the start. They first collect money)))

And you checked the project that advertised in the signature?

[revenanTts]

Now most projects do not have any smart contracts at the start. They first collect money)))

Now I will check every project I participate in, because it's a great tool for analysis!

[Banny_hopyy94]

I will check all smart contracts in which I invest and which I advertise.
I'll post the results here.
While I ordered an audit of the project, which I have in the signature.
How will the result - I will inform you.
You can check the projects in which you are participating.

It looks like soon will be ready to audit the smart contract that you have in your signature https://github.com/EthereumCommonwealth/Auditing/issues/16

P.S. Attention to those who sent requests! Check your email. I received a letter and you probably too.

Do I need to register with github? Without this, they will not agree to audit a smart contract?

This is not difficult to do (register with github). Follow the instructions received in the letter.
