CowSwap: first swap on a rollup to be filled with mainnet liquidity
A user on Rollup X signed one order. CoW Swap's solvers filled it against liquidity on Ethereum mainnet and the tokens landed back on Rollup X in the same transaction.
No bridge, no wait, no second signature.
New chains no longer have to launch with thin pools that users pay for in slippage.
