Flash loanFlash loan
Spark · Acts onchain
Borrows an asset from a Spark market with no collateral, repaid inside this transaction. The action opens a block: the steps inside it spend the borrowed funds, and before the block ends the socket must hold the principal plus the pool's flash premium, surfaced as the owed output, or the whole transaction reverts. Approval for the repayment is handled here. Reach for it to refinance debt between markets without capital, to unwind a leveraged position by repaying before withdrawing collateral, or to fund an arbitrage across venues. Coil owed into a comparison so a predicate requires the balance covers it before the block closes.
