Ethereum is one of the expensive chain out there. It has more burn for the transactions than anything else out there. It's on the shoulders of the layer 2 and layer 3 chains for minimizing this leaky bucket. And this means layer 2 chains are in demand at the point of the swap. Polygon, Optimism, arbitrum and immutable are being used for reducing the fees of the chain. Robinhood one of the popular exchange has decided to use the Polygon for the swap. 

This new change is being offered by the 0xproject and LIFI protocol. So those tokens supported by these two protocols would be added into the swap. So it would be possible to have the support to those chains and also easier and cheaper swaps due to the Robinhood's choice of going with the Polygon into the swap DEX. 

Knowing how the polygon and arbitrum are low in fees. We are going to see how the wallet and the transactions going on lower fees would be making a difference. In that context you can see that it would be reasonable to say that such benefit of the Robinhood would make their customers benefit out of such setup.
