That’s actually much better, as it’s massively easier to implement a flat rate I’d a thought.
The only risk of setting it too high is that some might try and game the system if the rebate exceeds the fee from a transaction that is not being included in a block by a miner. This would essentially set a floor on the gas fees.
At a level of 5 or 10 GWEI it will help those doing Uniswap trades (particularly non-whales), as it’ll also get people using Uniswap to stay on Uniswap as we’ll be cheaper than any other onchain platform. This should create more volume and organically increase TVL
