How to send bulk ERC20 tokens? Help needed. (Merit for help)

[Parodium]

Hey everybody,

I've been tasked with distributing a large number of ERC-20 tokens to bounty participants.

Does anybody know how to send a bulk number of transactions of varying amounts to around 1,000 Ethereum wallets?

Ideally looking for a way to send them as easily, and cheaply as possible.

Useful information will be rewarded with merit.

I think this might be helpful for you - https://hackernoon.com/how-to-script-an-automatic-token-airdrop-for-40k-subscribers-e40c8b1a02c6

And also you need an expert to write code for the distribution of tokens. This is what I understood and as far as I know, sorry if I am wrong.

Write a smart contract to which you assign required amount of tokens. The contract has a function to loop through given addresses and transfers tokens to those addresses from its balance. But you'll have to send more data into the blockchain.

There is multisender.app dApp. I have never used it and I can not assure it is safe. But I've seen some people recommend it and the code is opensource.

You'll need some smart contract for that. And since you don't seem to know how to create one, so it might not be a safe option to use someone else's. Anyways, the amount of tokens to distribute would be different, so not sure how much the smart contract can help you. You basically need some tool to input data directly from your spreadsheet and then broadcast the transactions.

Also one other point is that you want cheap option and contract based transactions are always more costly than the normal transactions. So I feel that you don't really have any other option than sending it manually. If you want, you can distribute the work to people you trust. That way you'll manage to send the payouts in time while avoiding overwork. I'm sure you can find people who can help you with this distribution task.
 
Between, if you do find an elegant solution to your problem, then please post it here.

Great information!

Do you have any idea what the gas costs are to send around 1,000 ERC20 transactions?

You will pay a fee of 0.05 ETH+ gas tx fees for each 145 address that you add or buy the VIP for 2ETH. The gas tx fees are the normal that the network needs to send a transaction.
