Re: Is there a way to send all ETH tokens at once?

I have an ETH wallet and there are many tokens in there. At least 20 erc20 tokens.
Simple question.
Is there a way to send all ERC20 tokens in one transaction to another ETH adress?

Here's the answer I've been waiting for.

There is a way. But you probably won't like him. You need to write a contract that will make the operation you are interested in.
If you are interested in how to do this, you can see, for example, here: https://medium.com/coinmonks/build-a-smart-contract-that-transfers-erc20-token-from-your-wallet-to-other-addresses-or-erc20-ee8dc35f40f6
But in your case, it is better to do several transactions manually. Not so many tokens you have.

Everyone says it can't be done. I know we can't. The purpose of opening this thread was to see such new ideas. Thank you for your attention.

Hmm, it is a good idea to find a way for sending multiple tokens in one transaction.
Because you can reduce the gas fee if you only send it in a single transaction.
If you have 20 tokens, you supposed to send them with 20x gas fee. But with single transaction, it means you only use 20x less gas fee, smart.
