XRP Ledger's new proposal blocks the flash loan attacks costing DeFi hundreds of millions

A draft XRPL amendment notes that flash loan attacks are "structurally impossible" on the network because of how its transactions are built, an architectural quirk that has spared the chain from the exploit class that has cost Ethereum DeFi billions. What to know : Recent DeFi exploits on protocols like Thorchain, Drift and KelpDAO have relied on flash loans, a mechanism that does not exist on the XRP Ledger. Because XRPL transactions are atomic and cannot include composable intra-transaction calls, flash loan attacks are structurally impossible on the network. As XRPL pursues AMM upgrades and its tokenized real-world asset volume grows, institutional investors may weigh this built-in exploit resistance against Ethereum’s deeper liquidity and more mature DeFi ecosystem.
