why does every new chain launch its own DEX from scratch instead of plugging into shared infrastructure

something that bugs me. every time a new L1 or L2 launches, one of the first things that happens is someone deploys a uniswap fork or builds a basic order book DEX native to that chain. it happens on every single chain. berachain, monad, sei, megaeth, whatever comes next.

and every single time:

• the liquidity is trash for the first 6 months
• the UX is a downgrade from what exists on established chains
• the smart contracts are rushed forks with minimal auditing
• the team burns months rebuilding something that already exists elsewhere

this is like every new city building its own power grid from scratch instead of connecting to the existing one.

what if new chains could just plug into a shared exchange infrastructure layer? one matching engine, one order book, one liquidity pool that works across chains. the DEX on each chain becomes the frontend, the brand, the community. but the execution, matching, and settlement layer underneath is shared and battle tested.

this model already exists in tradfi. nobody builds their own stock exchange from scratch. they connect to existing infrastructure. nasdaq doesn't rebuild itself for every new broker.

the crypto version of this would be a shared CLOB layer that any chain or protocol can deploy on top of. white-label the frontend, share the backend. you get instant liquidity from day one, proven execution, and you skip the 6 month bootstrapping problem entirely.

is anyone building this way or are we just gonna keep forking uniswap forever
