Have you tried @universaldotxyz's trading dashboard yet?

Feels like a CEX, but trading from your onchain wallet on @base, @solana, @world_chain_, and @arbitrum.

Trade the top 80 uAsset versions of the top crypto tokens onchain using offchain liquidity via on demand mint/redeem swaps.

Lots of improvements to make, but this is a pretty awesome showcase of what is possible using the API.
