Can I broadcast someone else signed transaction and use fee from my address? if yes then how?

Let me elaborate my Question Suppose person A want to transfer some ERC tokens to person B. But person A got zero ether in his account. so person A will sign the transaction and give it to person C and person C will broadcast the transaction. So in this case which account fee will deduct from person A's or from person C's. if it will try to take from person A i want something like it will take fee from person C's account.

Thank you!!

How Ethereum take fees in broadcast?

It doesn't. Broadcasting is free. Your assumption cannot be done.

  • Gotcha. OpenGSN is a bit different as it is not part of core Ethereum, but a separate project where GSN members can broadcast your transaction for a fee. I do not know how it works though - because it is very new and little uesd.

  • But it does not work with standard wallets and Dapps, you need to build specific support for it.

The ERC20 token standard requires an approve function to allow another address to spend tokens on behalf of the actual owner. It means that account C can authorizes account A to use a certain amount of C's token .
