DeepBook V3: Flash Loans SDK

The @mysten/deepbook-v3 SDK allows developers to borrow base or quote tokens from a pool's vault without collateral, perform arbitrate operations, and repay the loan in a single atomic Programmable Transaction Block (PTB).

All flash loan methods return a transaction-building function that appends calls to a Transaction object:
