I've come acrossed an article, Signing and Verifying Messages in Ethereum, where it says that you can pay for other user's gas transactions but so far I haven't seen any implementation or tutorial on how to use it on a Dapp.
My primary use of this smart contract is to pay transaction fees with my address for the user in my Dapp. Is there an example of how to use the smart contract for a dapp?
Example: A simple ethereum dapp that writes a text on the blockchain but the creator of the contract pays for the transaction fees for a user that owns 0 ETH.
I really hope this is possible.
