I've noticed that a number of altcoin projects distribute tokens via airdrops.

Members sign up with the ETH address using Google Docs or on the token's website. Often, several thousand people may sign up to receive a defined number of tokens.

How are these tokens being distributed in an efficient manner? Is there some kind of script that sends 100 ABC tokens to each of 5,000 addresses?

How do these airdrops work?

Yes there is a way to do that. It is done by scripts and a smart contract, script feeds the address list to smart contract in bulk packages, and smart contract sends them with the standard send command (looped).
The avarage cost of airdropping tokens is 0.1ETH per 1000 addresses ( I'm talking about gas cost only ). So for your examplary 5000 addresses, you'dpay 0.5ETH gas fee.

Thanks for the info about the gas cost. I can see, from the Twitter, that you are very knowledgeable about all the airdrops happening!

Do you know of any example smart contracts / scripts used? All of the tokens mentioned on your Twitter must be using such code.

Thanks.

yes for airdrops mostly smart contracts are used on the eth platform, just like they distribute tokens to the investors, similarly they set the parameters and addresses for airdrop tokens and then the process is automated.

Yes, I understand the idea.

However, I am wondering if there is any Solidiity code available that I can play with. Any ideas?

I now understand why some projects say they are giving airdrops yet end up asking for some ether in return. This is just for them to cover the cost (gas).

That along with the fact that some of those people never plan to airdrop a token and just want to get a little bit of money from everybody before running away. The utmost low scam of scams, but hey you know somebody out there is going to attempt it.

I've always been curious about the process because I signed up for an airdrop the other day where they're airdropping 15,000 tokens to every person that signs up. Pretty crazy to think about the logistics.

I don't know but probably it is done with smart contracts, but there must be some ways to avoid multiple registrations otherwise they dump lots of airdrop token after the ico.

I agree with you! To do this with scripts and a smart contract, the script provides the address list for intelligent contracts with bulk packages, and the smart deal sends them with the standard send command (looped ). The problem is how to calculate costs. It's not too high but many investors are still wondering.

Most Altcoin taken from airdrops are shit coin. They do not really do well. Most become valueless once they get released.
The best airdrops so far is polymath.

Mostly they do. I have a low amount of uservice tokens and they promised every month approximately 15% for holding the tokens. The first month I have got the tokens now I am waiting for the next distributions.

Yes there is a way to do that. It is done by scripts and a smart contract, script feeds the address list to smart contract in bulk packages, and smart contract sends them with the standard send command. Searched this and this infos came out. I hopes this helps
