Flash Loans
Flash loans can be performed essentially by building a Solana transaction, where starting instruction is the
FlashLoanBegin
and last instructions is the FlashLoanEnd
from the mango V4 program. The intermediate instructions can call any solana program of choice. FlashLoanBegin
transfers tokens from the mango V4 vaults to the token accounts of choice, and FlashLoanEnd
moves the excess (in comparison with amount before the transaction) amount per token back to the vaults.Constraints
- Borrowing for a particular token can only be done once
- Cannot be called from cross-program invocation
- The only mango V4 instructions allowed are the
FlashLoanBegin
andFlashLoanEnd
- The initial health of the involved mango account at the end of the transaction must either be above 0 or better than the initial health before the transaction
