XRPL design blocks flash loan attacks, sets DeFi standard

A draft XRPL amendment claims its atomic transaction design blocks flash loan attacks, distinguishing it from Ethereum and potentially shaping DeFi security.

A new draft amendment to the XRP Ledger (XRPL) emphasizes that flash loan attacks—responsible for billions in DeFi losses—are structurally impossible on its network. This is due to XRPL’s atomic transaction design, which ensures each transaction is self-contained and does not allow intra-transaction calls. In contrast, Ethereum’s composable smart contracts enable multiple operations within a single transaction, making flash loan exploits possible. Attackers on Ethereum can borrow, manipulate, and repay funds within one block, a vulnerability not present on XRPL. The proposed amendment, AMM Swappable Curves, highlights this security advantage as XRPL expands its automated market maker features. With recent exploits on platforms like Thorchain and KelpDAO, XRPL’s resistance to such attacks is drawing attention and may influence future DeFi security standards.
