I am working on a solidity contract and on each ethereum received in contract, I want to distribute ERC20 token propotional to ether spent in that transaction to 7500 addresses at once.

To do there could be these 2 ways as given below:

  1. To transfer them token at the same time.
  2. To save that amount so they can claim later. (push/withdraw method)

But in both the ways I will run out of gas.

Any help will be appreciated. Thanks.

  • Could you add more context to the question? When do you wanna transfer the ERC20 tokens? When, you receive ether from them in your smart contract? Dec 17, 2021 at 9:16
  • suppose their is a function which accepts ether and distribute ERC20 token Dec 17, 2021 at 9:25

you might be able to play with the balanceOf for specific addresses. Essentially the set of addresses you specify would have a starting balance of 0 + x. I think setting the addresses in a single mapping would be considerably cheaper. You might get tot higher amount of "distributions" through this method.
