Set it too loose and you eat poor fills or get sandwiched. JIT Routing was built to close that gap.How does JIT Routing work? The router still produces a quote off-chain. The difference is that it prepares more than one candidate path, and the transaction itself carries conditional logic. When it executes onchain: The smart contract checks each candidate pool's current state. It picks the one with the highest output. Everything settles in a single atomic transaction.
