The claim is likely true in substance. The directly fetched CryptoSlate article explicitly states the core claim: a $292 million exploit triggered roughly $10 billion in DeFi withdrawals. Independent corroboration appears in search results from CoinDesk, Decrypt, Yahoo Finance, and MEXC, all of which describe the same exploit leading to very large DeFi outflows, especially from Aave. However, the exact figure varies across corroborating sources, with some citing about $9 billion or about $13 billion rather than exactly $10 billion. Because the linked X posts and The Block articles could not be fetched in this run, the exact number cannot be confirmed from a primary source here. So the best-supported assessment is that the claim is directionally and likely factually correct, but the precise $10 billion number remains only moderately validated.
