Hi, is there any function or some smart contract to take example from to do the following:
The idea is to take a small fee percentage (0.2%) before calling a transfer function and not spending on gas fee ?
The fee percentage function should be a separate function.

I searched on Google and the only one I came across was the Uniswap smart contract but it isn’t what I need

Gas fee is required no matter what to change any state on the blockchain
What is your end goal? Have the tax pay for the gas?

nope, the goal is to get a fee when a users use our dApp of reports, but the idea is to avoid that the users spend on gas fee for transfering a small amount of fee (0,25%) for the service

let's say a user has 100 $, he connect the wallet and create a report and before that the user do the creation we want to cut a 0,25% for the report generation so basically 0.25 $ of fees

checking the transfer in ETH it will cost 1.35 $ for the transfer + 0.25 $ for the fees, so 1.60 $ total on spending for the fees part which we ipotetically want the user don't spend

You could look into a relayer where you would pay the gas for them

Openzeppelin has one

so there is no way to spend less on transferring ?

if there would be a way to spend less- every wallet would use it. The current state is nash equilibrium

there is a minimum gas cost of 21k wei to make a tx
