createBuyPtInstruction

Buys PT tokens from base assets in a single atomic operation. This is an alias for the buyPt instruction which handles the base-to-SY conversion internally via CPI remaining accounts. The caller supplies base tokens and receives PT directly, without needing to manually mint SY first.

​
