Flash Loan Smart Contract

[ghost]

Are there any example contracts for taking out a flash loan and interacting with a DEX such as Jupiter?

What about just initiating a flash loan without calling an API from Jupiter?

Just the taking out of Solana and then buying a specified token?

It's the same way, the Jup API in that example is completility swapable.

Create a withdraw ix
const withdrawIx = await marginfiAccount.makeWithdrawIx(withdrawAmount, usdcBank.address);

Create a deposit ix
const depositIx = await marginfiAccount.makeRepayIx(usdtAmountToRepay, usdtBank.address, true);

Add the IX's that you wish to use the funds for in between of them, and you the transaction

const flashLoanTx = await marginfiAccount.buildFlashLoanTx({
    ixs: [...withdrawIx.instructions, whateverYouWantIX's, ...depositIx.instructions],
    addressLookupTableAccounts,
  });
