Using jupiter swap instructions for faster transactions

Question

Just looking at jupiter's documentation. I notice it has /swap and /swap-instructions It appears that /swap-instructions gives you an instruction payload with which to utilise transactions in a solana VersionedTransaction, as opposed to using /swap to pass through your quote.

Is there any benefit to doing this? Would it result in a faster creation of VersionedTransaction or is the difference negligible to the point that the use case is for something else?

Answer 1

Performance-wise, it doesn't change anything (after all /swap is just a Transaction/VersionTransaction populated with the contents of /swap-instructions). The reason this endpoint exists is for composability with other programs, i.e. you want to add other instructions before and/or after your swap in the same transaction.
