I have come across a few airdrop forms asking you to send 0eth to a contract to receive coins.
My question is
If this is a kind of scam.
What are the implications of sending the zero eth to the contract address.
Will be very grateful if someone here can do well to enlighten me

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

Not a scam, as I understand it
This is necessary in order to complete a smart contract.
You send 0 ETH (but still paying gas for this transaction) and receive some tokens to your wallet.
It works in same way as during ICO, but on ICO you need to pay more than 0 ETH usually, and for airdrop amount just set to zero.
P.S. I'm not a smart contract programmer, correct me if I'm wrong

Good to know. I was wondering if such a case will not end up in my own coins or eth disappearing from my account. |

They can't scam you by getting the Ethereums in your sender wallet, if you mean this kind of thing. They do this to see if you're the one deserving that airdrop. But, I'm not saying they're not a scam thing. What I'm saying they can't scam you with this method. |

But it will less your eth, when you send 0 eth it will automatic send the token. But ofcourse in every airdrop we need to be careful in order to not get hacked. |

I just found out the scheme. To my knowledge, there is no problem if we just send 0 eth. Maybe it's just a verification requirement to get you qualified for the person receiving the Airdrop. And also to avoid multiple accounts for Airdrop to run fair. Of course, it's not scam  |

it is possible to he a scam , why would anyone send eth to a contract , which is an airdrop. Airdrop meant to be a free , as you send an etherium to it , it wouldn't be an airdrop anymore , because you just pay what will they honna give you in return. |

I do not think so, They want to check the account to avoid a user multiple accounts, and Coin has grown or not depends on the developer and the interest of the community. |

Hacked should have been the word to use rather than scammed. No one knows how the contract was written. There is the small chance it's all meant to have your account hacked. |

I think the drop should be fair, not to say that setting some bizarre conditions does not seem plausible. |

By sending 0 eth, it does not have access to your account. There is no program that can access to your account unless they have the seed words, which in turn the legit program that you are using to send transaction should not give. There are a few ico doing this and one of the most successful and popular ICO is blockmason. The reason for this act is very simple, you create a transaction that has a link from your eth address to the smart contract address, this will invoke a certain function in the smart contract to register your eth in their database. If we are talking about airdrop program, there will be another function in the smart contract to distribute the tokens to the registered database in the smart contract.

Sending Eth to an aidrop is a risky move,but if you trust the aidrop you are joining then go for it.

A few months back a hacker was able to exploit the etherDelta exchange (it's a decentralized exchange which operates via eth contract calls). They used the etherDelta contracts themselves to run the code in their black hat contract. The etherDelta contracts interacted with the black hat contracts which then transferred private key information from the client's wallets thru their browsers and back to the black hat files.
In other words, be careful interacting with ethereum contracts ---> read the code before you interact with the contract. If the code looks peculiar ---> ask questions before you interact with it. Remember, ethereum is a turing complete platform and we are still in a relatively new and under explored realm. Careful!

Thanks. My thoughts exactly. Ethereum is completely new and unexplored realm. That's why I am afraid someone would have found a way to exploit a loophole. I remember an ico that failed to reach the hardcap and we were asked to send 0 eth to the contract address to retrieve our investment. Hence my fear that I send 0 eth and my assets find their way out |

You are absolutely doing the right thing by asking the question. Whenever you join an airdrop, download a wallet etc... in short whenever you interact with something new, it is always important to determine whether it is safe, and how you could possibly make yourself vulnerable. Eth and crypto in general are still very young and by no means fully explored. Always be vigilant!

Thank you very much. Nice advise to get a new wallet for such transactions. Problem though is that they ask for aboutique 5 or more minimum previous transactions on the wallet to qualify for such airdrops. |
