Hi, if you do this per Swap that wouldn't make much sense because you would have to pay for the bridging. But I think it is still cheaper because currently paying $100 per swap on Uniswap is the norm...

But the best way to use it is to batch bridge a lot of USDT or USDC tokens to Matic network once, and then swap & trade the tokens carefree for as much as you want until you want to lock in the profits and bridge back to Ethereum
