We need a decentralized exchange with the functions of Binance/Coinbase

By the functions of Binance/Coinbase, I mean an exchange that is cross chain and has lots of coins and tokens listed. But ideally something that looks like Binance or Coinbase to a user.

The US government is intent on killing centralized exchanges that serve US customers (which btw beautifully illustrates the problems with centralization)

Is anyone working on this? I know it would be very technologically challenging given it would need to have decentralized liquidity providers (potentially split across multiple chains). Maybe something on an L2 where everything is wrapped? That's not ideal though because it isn't as simple as Binance or Coinbase and if we want mass adoption it needs to be simple af
