As i know, ton s smart contract execution between external contract is asynchronous, then if there is dex using x×y =k , how to make atomic swap using more than 2 paths?

Maybe liquidity need to be stored in one contract? Like balancer?

You can't make atomic swap between 2 pairs

So need new dex mechanism in ton?
